Liver Transplantation Program
Hacettepe University Liver Transplantation Program; has been one of the leading centers in its field since 1998. First adult liver transplantation was performed on 28/02/1998 while first pediatric liver transplantation was performed on 13/04/1998 in our center. Survival rates for liver transplantation patients of our center for 1, 3, 5 and 10 years were respectively 95 %, 80%, 78 % and 78 %.
Hacettepe University Faculty of Medicine Liver Transplantation Program provides service in Hacettepe University Adult Hospital which offers the opportunities to give any type of treatment to chronic liver patients.
Liver Transplantation Process
Transplantation consists of 4 stages. First stage is evaluation. If you are deemed as the suitable candidate for liver transplantation, you will have 2 options: transplantation from cadaver or living donor. 2nd stage starts once you register in Ministry of Health Turkey Organ and Tissue Information System (TODS) for transplantation from cadaver and continues until compatible organ is found. 3rd stage is the liver transplantation surgery in the event that a compatible organ is found. 4rd stage is post-transplantation immunosuppressive (medication to suppress immunity) treatment and control process.
The process of your evaluation for liver transplantation starts as of you are accepted as a potential receiver for liver transplantation within Hacettepe University Liver Transplantation Program and continues until you are registered into the organ waiting list or you are deemed to be unsuitable for transplantation.
Evaluation process
Evaluation process for liver transplantation involves several tests, interventions and meetings with the members of transplantation team. Furthermore, you may need to meet with other specialists outside the team. All of these consultations, tests and other procedures help us to decide if liver transplantation is the correct treatment for you and if you are sufficiently healthy for liver transplantation, which is a highly major and risky surgery. These tests also help us to decide if there are any other treatment options than liver transplantation suitable for you.
After your evaluation process ends, your file will be reviewed at Hacettepe University Council of Liver Transplantation Liver and it will be concluded if liver transplantation is the most appropriate treatment option for you. Council's decision will be communicated to you by your physician.
Liver Transplantation Team Members
Liver transplantation team consists of; General Surgery Specialist and / or Pediatric Surgery Specialist (trained in liver transplantation), Adult Gastroenterology Specialist, Pediatric Gastroenterology Specialist, Psychiatrist, Anesthesiology and Reanimation Specialist and Organ Transplantation Coordinator.

After the Evaluation Process
If you have been deemed suitable for liver transplantation, you are included into the national information system consisting of active members waiting for transplantation from cadaver. Transplantation team should be able to contact you 24/7. You should arrive in hospital within a short period of time once compatible liver is found. Please make sure to give all of your contact numbers to organ transplantation coordinator. You should contact organ transplantation center in the event of address or teletelephone number changes.
Patients in the information system should periodically come to controls for evaluation.
MELD Score
In Turkey, the recipient of a liver harvested from a cadaver donor is decided based on MELD ( Model for End-stage Liver Disease) score of patients registered ad National Information System for liver transplantation. The score is calculated by using 3 variables (bilirubin, creatinine, INR). A patient with a higher score is more likely to be lost due to liver disease in this system that calculates the survival possibility of patient in need of liver transplantation.
Adaptations are applied in certain situations (for instance hepatocellular carcinoma patients)
Score is used for patients younger than 18.
MELD score should be recalculated and updated periodically based on MELD score.
Which Patients are Candidate Recipients?
Patients suffering from incurable liver disease with associated complications such as abdominal fluid accumulation, loss of consciousness, peritonitis, decreased life quality, etc.) are candidates for liver transplantation.
Diseases that could lead to incurable liver diseases
1: Acute liver failure (due to mushroom, drug, etc. poisoning)
2: Congenital absence of bile duct
3: Metabolical diseases:
-
o Alpha-I antitrypsin deficiency
-
o Crigler-Najjar disease, Type I
-
o Byler disease
-
o Glycogen storage diseases
-
o Wilson disease
-
o Hemochromatosis
-
o Tyrosinemia
-
o Familial amyloidotic polyneuropathy
-
o Primary hyperoxaluria type 1
4: Liver cirrhosis (Reasons can be Hepatittis B,C, Alcohol, NASH, etc)
5: Hepatic vascular diseases
6: Liver tumors
Liver transplantation Types
Transplantation from cadaver
The procedure involves transplanting the entire or a part of the liver harvested from a cadaver instead of your diseased liver to be removed.
Transplantation from living donor
The procedure involves transplantation of a part of the liver of a healthy individual.
Post Transplant Life
After the organ transplantation, you should take medication to suppress your immune system everyday so that your body does not reject the transplanted organ.
Several patients are nervous while departing from this environment, but the suggestions given below will help to create and maintain a safe environment at home.
Your medication
Your physicians and nurses will inform you on how to use your medication. You should take your medication regularly. If you have trouble in maintaining regular medication intake, you should receive support from family members in this regard.
Controls
You should pay control visits 3 times a week nice you are discharged from hospital. You should come to control examination without taking your medication before as your medication levels will be observed.
The frequency of your control examinations in the long term will be stated to you by your physician.
Home Environment
Living flowers and plants should not be put into patient room as these can be source of infection.
Pets should be avoided after transplantation. You can talk to your cat or dog with a distance in between. But you should by no means allow your pet to contact and lick you or sleep together with you.
Personal Contact
Close contact (hugging, kissing, hand shaking) should be avoided in order to reduce the probability to exposure to bacteria and other agents that could cause infections.
Persons who are not suffering from any infectious disease or upper respiratory tract infection can visit you after they wash their hands. The best protection is to avoid crowded places in the initial days.
You should avoid contact with persons suffering from upper respiratory tract infection (such as flu). Live vaccine should be avoided.
Daily Cleaning
Taking showers or bathing frequently are good for you. You can use a mild soap particularly in the event of a rash. You should avoid using soap with strong scent.
You should check your skin. Immediately inform your physician or nurse in case of a redness, puffiness or itchiness on your skin.
Always use your own towel and clothes. Do not use such belongings used by others and do not allow anyone else use what has been used by you.
Sea and Swimming Pool
Do not swim in lakes or public swimming pools as your immune system will have been suppressed. Do not engage in activities such as swimming without consulting to your physician.
Daily Exercise
Regular exercising is an important part of recovery process. Restoring your muscular strength and motion with exercise will make you feel good not only in physical but also in emotional terms.
You will feel that your resistance to activity or exercise has dropped down after you are discharged. Daily routine exercises can be very difficult at the outset as your energy level can be low or you might not feel good. Planning both resting and exercising periods together can help.
Sexual Life
Sexual activity subsequent to transplantation depends on how you feel yourself. Both male and female patients should inform a physician or nurse in the event of a discharge, skin lesion, chap or rash in the genital area. Sexual intercourse should be avoided until full recovery in the event of an active infection in your partner.
Nonetheless, birth control is of major importance. Transplantation team will inform you on the birth control options available.
Fever
If your fever reaches up to 38 degrees celsius and does not go down to normal level in 2 hours, you should call your nurse or physician.
Circumstances in which you should inform your transplantation team:
• Fever above 38 degrees celsius
• any bleeding from the palate, nose, rectum or bladder
• Cough, nasal congestion or shortness of breath,
• Nausea, vomiting or diarrhea,
• Skin rash or redness (check on a daily basis while in the bathroom),
• Any problem, pain, swelling, redness or discharge in the surgery site
• Mouth sores or rectal pain
• Genital scars, vaginal bleeding, discharge or odor.
• Frequent urination, pain or burning during urination,
• Yellow color on your skin or the white parts of your eyes
• Itchy skin
Smoking/Alcohol/Medication
We suggest you not to smoke after transplantation. Additionally, you should not allow anyone smoke near you and avoid from environments where tobacco is smoked.
Alcohol intake after transplantation should be avoided as well. It is not recommended as alcohol intake while taking medication on a regular basis should be avoided.
If you need to use any medication for a reason, consult with your physician or nurse. The medication given to you might not be compliant to the medication that suppresses your immune system, so you can change the expected effect.
Nutrition
As your immune system is suppressed, a great risk is posed in respect to the infections spreading with food.
The majority of food includes certain types of bacteria which are usually harmless for anyone who has a full-functioning immune system. This being said, food which includes high level of bacteria can be harmful to certain people and these food types can be a source of infection.
This section sets out information on considerations about selecting, buying, preparing and storing food in the post-transplant period.
Considerations about preparing and storing food are as follows:
-
• Start with cleaning your fridge and make sure the temperature is set below 5 °C.
-
• You should buy new food for your first arrival at home from the hospital. Discard or move away open cans or packages for a while.
-
• Remember to wash your hands frequently.
-
• Keep all the areas you prepare food in a clean and dry condition.
-
• Wash plates with hot water and soap, and set them aside as soon as they dry up.
-
• Be careful while handling kitchenware and hold them from their grips or edges.
-
• Keep your fingers off food.
-
• Put on gloves while preparing food with any injury or open wound in your hands.
-
• Make sure not to cough or sneeze near food or plates.
-
• Check the expiration date of all products.
-
• Cook all types of meat and eggs well.
-
• Keep meat and prepared food in the fridge only once. Keep all the food in the fridge in containers with closed lids.
-
• Leftover food should be served after it is re-cooked.
-
• Leftover food should be eaten within 24 hours or packaged and frozen.
Medication to be used by liver transplantation patients
IMMUNOSUPPRESSIVE DRUGS
Immune system is the body’s defense system. It serves to the purpose of defending the body against factors causing diseases and ensures body’s resistance against these factors. If the immune system is strong, body overcomes these factors so that there won’t be a disease. After the heart transplantation immunosuppressive drugs are used to prevent the rejection of the transplanted organ by the recipient’s immune system. Therefore, while you are on immunosuppressive drugs, you have to protect yourself from diseases and related factors, better than you did before. Period of use and dosage of these drugs are determined/arranged by your physician and these are modified depending on your condition.
Immunosuppressive drugs repress your immune system and weaken it. In other words, they suppress your body’s defense mechanisms (which it normally has) that attack and reject foreign tissues. It helps your body to accept the new organ. While these drugs prevent organ rejection, on the other hand, these decrease your body’s defense against infections. While you are on immunosuppressive drugs, your body is open to infections; besides, while you are on this treatment, you should not be vaccinated with live viruses. You should consult to your doctor and transplantation team in every case of medication use and vaccination.
General Side Effects of Drugs
Opportunistic infections; cytomegalovirus, fungus, herpes simplex (blain, cold sore) are observed commonly
An increase in malignant diseases may occur. Therefore, you have your medical controls regularly.
Do not change or skip doses without consulting your doctor. Use medication according to recommended dose and directions. Even before using a simple drug -even if it is recommended by another physician- you should consult to your own doctor. Please remember to take your medication with you while travelling. Do not switch drugs with others. Even if they have the same content, before switching your drugs, please do consult with your physician.
Prednisolone (Deltacortril)
It has an immunosuppressive effect.
The dose of Prednisolone decreases to the maintenance dose. You will keep using prednisolone unless otherwise stated by your physician. If you receive the medication in a single dose, you should take it after breakfast with a full stomach.
Side Effects
It can cause water and salt retention, increase in gastric and perspiration acidity.
The risk of fungal infection in mouth increases. Increased hairiness and acnes on skin might be observed. It may cause muscle and bone weaknesses in the long term.
It may cause cataract and increased blood glucose. Psychological problems are observed more commonly.
Prograf (Tacrolimus)
By blocking T cells, it prevents T cells to damage the transplanted organ. Mechanism of action is similar to cyclosporine and cannot be used together with it.
The given circumstances for cyclosporine also applies to tacrolimus.
High blood levels disrupts the kidney functions. For this reason, blood values should be followed up closely. Please have your blood values tested whenever your physician instructs you. To obtain accurate and correct results, please use your medication on time and regularly. The dosage arranged according to tacrolimus level in blood. It has similar side effects with cyclosporine. Cosmetic side effects (pubescence, swollen gingiva etc.) are observed less, while drug related diabetes and neurological symptoms are observed more commonly.
Do not take the medication with grapefruit juice. Grapefruit juice affects blood levels. Do not drink grapefruit juice 2 hours before or after receiving medication. Certain drugs (such as ketoconazole, erythromycin) may have greater effect the level of tacrolimus. Therefore, as it was mentioned before, please do not take any medication without consulting your physician, even if it is recommended by another physician.
Take the drug only with water.
Cellcept(Mikofenolate Mofetile – MMF) and Myfortic (Mikofenolate Sodium)
Cellept, an inosine monophosphate dehydrogenase inhibitor, prevents the rejection of transplanted organ by body. Usually, it is taken with cyclosporine, tacrolimus and/or sirolimus. It should not be taken together with the anti-acids containing magnesium and aluminum hydroxide since it will decrease the absorption.
Most common symptoms are diarrhea, decrease in leukocyte count, nausea, vomiting. It causes an increased tendency to certain infections.
Cyclosporine (Neoral-sandmimmun)
It is an immunosuppressive drug. It shows its effect by blocking T cells. It has two forms: oily liquid and pills, both of which are taken orally. Capsule form is swallowed with a liquid like other medications. If you are using the fluid form, your physician or nurse will show you how to adjust the dosage. You should take the proper dosage of medication immediately after mixing it with milk (room temperature heat), chocolate milk or orange juice. Do not forget that you should never take cyclosporine with grapefruit juice! If you have taken the medication, please do not eat grapefruit for at least two hours.
Please take your medication regularly and at the same hour everyday, as it will help you to keep the medication in your blood at the same level at all times. If you forget to take the medication and you remember in 1-2 hours, take the missing dosage immediately, keep your regular schedule. If you don’t remember to take it until the time of the next dosage, do not take two dosages at once, and consult with your doctor. If you have diarrhea and/or vomit, inform your doctor immediately. Diarrhea causes disposal of drug before it affects your system. So that, it may cause rejection of transplanted organ. In this case, the drug will be given to you through an intravascular line. At this period you should avoid using laxatives.
Keep your medication in dry place, and in room temperature. Direct exposure to sun, storage in the fridge, extreme hot or cold weather will cause the drug lose it efficiency. Also, if you are using the fluid form of the drug, do not use it once it has been 60 days after opening it. You will be required to check cyclosporine level in your blood regularly. On the test days you have to take and bring your medicine as you were told to do. Please have your blood values tested whenever your physician instructs you. To obtain accurate and correct results, please use your medication on time and regularly.
Do not take the medication with grapefruit juice. It affects blood level. Do not drink grapefruit juice two hours before and after the time of medication. Certain drugs (such as ketoconazole, erythromycin) can have greater effect on the level of cyclosporine. Therefore, as it was mentioned before, please do not take any medication without consulting to your physician, even if it is recommended by another physician. You may take the medication with orange juice or milk.
Side Effects
Cyclosporine may have severe side effects. Commonly, it may cause hypertension. After you start taking the medication, your blood pressure should be monitored regularly. If it is necessary, your physician may recommend you to take your pills for blood pressure. Blood cholesterol and triglyceride levels might increase. Kidney and liver functions might increase. For this reason, you should do your laboratory checks regularly. Your hands may start shaking as well as headache, cramps in legs, swollen gingiva, nausea and vomiting. Also, your hair may get thick and wayward and shape and its form and dispersion may change to some extent.
You should be careful about the oral hygiene since long-term use of the drug may cause swelling in gingiva. You should brush your teeth after each meal and have your teeth checked once in every 4 to 6 months. Your dentist should also know about this medication.
You have to tell every side effect you are experiencing to your doctor. There might by grow of hair, kidney function disorder, nausea and vomiting and headache may occur. Please do not forget that the problems related to this drug will decrease in time with the decrease in dosage.
Rapamune (Sirolimus)
Rapamune (Sirolimus) prevents rejection of transplanted kidney by suppressing your immune system. In certain circumstances, it is used to treat acute rejection. It is used with cyclosporine and prednisone.
Rapamune (Sirolimus) in 1-5 mg dosage. It has liquid and tablet forms. Liquid form can only be mixed with orange juice or only water. It should be mixed in a glass and consumed before it precipitates. If Rapamune (Sirolimus) is used with cyclosporine (neural), it should be taken once in a day after four hours of the morning dosage of Neodal. Liquid form should be maintained inside fridge and the tablet form should be maintained somewhere dry and cool.
Side Effects
Rapamune may decrease white blood cell count, therefore it increases the risk of infection. Also, it may cause risk of bleeding by lowering the thrombocyte count. By adjusting dosage these two side effects may be decreased.
Rapamune may cause indigestion, diarrhea, nose bleeding, headache, joint pain, and increased level of cholesterol and lipid.
Certican (Everolimus)
It is an immunosuppressive drug which suppresses T cell activation and reproduction. It is only for oral use and should be taken two times a day. Tablets are taken with water without crushing and should be swallowed in one piece. It should be taken at the same time everyday. It should only be taken with water. When it is taken with fatty foods or grapefruit or grapefruit juice, its absorption decreases.

Heart Transplantation Program
The Hacettepe University Heart Transplantation Program has continued to be one of the most important centers in its field in our country since 1989. Adult and pediatric heart transplants are performed successfully at our center.
What Is a Heart Transplant?
A heart transplant is the replacement of a heart that has stopped functioning due to disease with a healthy donor heart. A heart transplant is generally performed for patients whose condition does not improve despite medication and surgical treatment. Although the transplant operation is a major surgical procedure, good results can be achieved with appropriate care and follow-up.
Why Is a Heart Transplant Performed?
A heart transplant is performed in cases of heart failure in which improvement cannot be achieved with other treatment methods. The causes of heart failure in adults are as follows:
• Coronary artery disease
• Weakness of the heart muscle (cardiomyopathy)
• Heart valve diseases
• Congenital heart defects
• Failure of a previous heart transplant
Patients under 65 years of age who have reached the final stage of heart failure and have a life expectancy of less than 1 year are candidates for a heart transplant. Older patients may become transplant candidates after their physical condition is evaluated.
The most common causes of heart failure in children are congenital heart defects and weakness of the heart muscle.
How Does One Enter the Heart Transplantation Program?
When the doctor following the patient believes that a heart transplant is necessary, they refer the patient to the heart transplantation council. The patient's condition is evaluated at the heart transplantation council, which meets regularly. If the council finds the patient suitable and decides on a transplant, the patient is admitted to the program and registered on the organ waiting list. Of the patients placed on the waiting list, those whose condition allows them to live at home wait for a suitable heart at home and come in for check-ups, while patients in serious condition wait for a suitable heart in the hospital.

What Is Done When a Suitable Heart Is Found for a Heart Transplant?
What Is Done When a Suitable Heart Is Found for a Heart Transplant?
The preparation process begins for patients matched with a suitable donor. After all preparations are completed, part of the heart transplant team goes to the relevant center to prepare the donor heart. The other part of the team prepares the recipient for surgery. When the recipient and donor are ready, the heart transplant operation is performed.
What Are the Risks of a Heart Transplant?
The most important risk after a heart transplant is rejection of the donor heart by the recipient. The recipient's immune system perceives the donor heart as foreign tissue and tries to remove it from the body. To prevent this, all patients who have had a heart transplant are given medications that suppress the immune system after the transplant. Even so, signs of tissue rejection appear in about 25% of patients in the first year after the transplant. When such signs appear, treatment is usually possible by adjusting the medication. If the medication is not adjusted, or if the patient does not follow the adjustment, tissue rejection can be very severe. For this reason, it is very important for patients who have had a heart transplant to follow their doctors' recommendations.
Other risks:
• Arterial problems. After the transplant, thickening and hardening may occur in the coronary vessels of the heart. This can impair the blood supply to the heart and lead to events such as heart attack, heart failure, rhythm disorders and sudden death.
• Side effects of medications. The immunosuppressive medications that must be used for life after the transplant can cause organ damage, especially in the kidneys.
• Cancer. Medications that suppress the immune system can increase the risk of cancer. The risk of developing skin, lip and blood cancers in particular may increase.
• Infections. Medications that suppress the immune system reduce the body's ability to fight infections.
Heart Transplant Surgery
The transplant operation takes about 4 hours. This time may be longer in patients who have previously had heart surgery or if a complication develops during the operation. The patient's chest cavity is opened, the patient is connected to a heart-lung machine, and the heart is taken out of circulation. The patient's heart is removed and the prepared donor heart is attached to the patient. The patient is disconnected from the heart-lung machine and the procedure ends. After the operation, the patient is monitored in intensive care. The length of hospital stay is about 1-2 weeks. At the discharge stage, the patient's medication treatment and cardiac rehabilitation program are arranged.
Results of Heart Transplantation
IMMUNOSUPPRESSIVE MEDICATIONS
The immune system is the body's defense system. It provides the body's resistance to disease-causing agents and is responsible for its defense. If the immune system is strong, the body overcomes the disease-causing agent and illness does not occur. After a heart transplant, medications that suppress the defense system are used so that the person's defense system does not reject the transplanted heart. Therefore, as long as you use these medications, you need to protect yourself better against disease-causing agents. The amount and duration of use of these medications are arranged by the doctor following you and are changed according to your condition.
Immunosuppressive medications suppress and weaken the body's immune system. In other words, they reduce the power that your body normally has to attack and reject foreign tissue. They help your body accept the new organ. While these medications prevent rejection, they also reduce your body's resistance to infections (catching germs). While you are using immunosuppressive medications, your body becomes open to infections; in addition, you must not receive live virus vaccines during this treatment. You need to consult your transplant team about the use of any medication and vaccine.
General Side Effects of the Medications
Opportunistic infections; diseases such as cytomegalovirus, fungal infections and herpes simplex (cold sores) are observed more frequently.
An increase in malignant diseases may be observed. For this reason, you should have the doctor check-ups mentioned above done regularly.
Do not change medication doses or skip doses unless recommended by your physician. Use them at the recommended dose and in accordance with the instructions for use. Whenever you are going to take any medication, even a very simple one, and even if it has been recommended by another physician, be sure to consult your doctor before taking it. Do not forget to take your medications with you when you travel. Do not swap medications with others. Even if the ingredients of the medications are the same, do not change medications without asking your doctor.
Prednisolone (Deltacortil)
It has an immunosuppressive effect.
The prednisolone dose is reduced gradually until the maintenance dose is reached. Unless your doctor tells you otherwise, you will continue to take prednisolone. If you take it as a single dose, you should take it after breakfast in the morning, on a full stomach.
Side effects
It may cause salt and water retention in the body, and increased stomach acid and sweating.
The risk of fungal infection in the mouth increases. Acne (pimples) and increased hair growth may be observed on the skin. In the long term it may cause bone and muscle weakness.
It may cause cataracts and a rise in blood sugar. Psychological problems are observed more frequently.
Prograf (Tacrolimus)
It blocks the function of T cells, preventing them from damaging the transplanted organ. Its mechanism of action is similar to that of cyclosporine, and the two are never used together.
The points mentioned above for cyclosporine apply equally to tacrolimus.
High blood levels impair kidney function. For this reason, blood levels must be monitored closely. Be sure to have your blood level checked at the times your doctor tells you. For blood levels to give accurate results, be sure to take your medications regularly at the specified times. The medication dose is adjusted according to the tacrolimus level in the blood. Its side effects are similar to those of cyclosporine. Although cosmetic side effects (hair growth, gum swelling, etc.) are seen less often, drug-induced diabetes and neurological findings may be observed more frequently.
Do not take your medication with grapefruit juice. Grapefruit juice affects the blood level. Do not drink grapefruit juice for at least 2 hours before and 2 hours after the medication time. Some medications (such as ketoconazole and erythromycin) can greatly affect the tacrolimus level. Therefore, as mentioned before, even if another physician recommends it, be sure to ask your doctor before starting any medication.
Take your medication only with water.
Cellcept (Mycophenolate Mofetil - MMF) and Myfortic (Mycophenolate sodium)
Cellcept, an inosine monophosphate dehydrogenase inhibitor, prevents the body from rejecting the transplanted organ. It is generally used together with cyclosporine, tacrolimus and/or sirolimus.
Antacids containing magnesium and aluminum hydroxide reduce absorption and therefore should not be taken together with it.
The most common side effects are diarrhea, a decrease in white blood cell count, nausea and vomiting.
It causes an increased tendency to various infections.
Cyclosporine (Neoral - Sandimmun)
It is a medication that suppresses the immune system. It works by preventing the activation of T cells. It has two forms: oily liquid and capsule. Both are taken by mouth. The capsule form is swallowed with a little liquid like other medications. If you will be using the liquid form, your nurse or doctor will teach you how to measure the dose. You need to mix the dose appropriate for you with room-temperature milk, chocolate milk or orange juice and drink it immediately. However, you must make sure that no medication is left in the container in which you prepared it. One thing to remember: never take cyclosporine together with grapefruit juice! If you have taken the medication, do not eat grapefruit for at least two hours.
You must take care to take your medication at the same time every day! This will help keep the medication at the same level in your blood. If you forget to take the medication and remember within two hours, take the missed dose immediately and continue to keep to your medication times. If you do not remember until the time of the next dose, never take two doses; consult your doctor.
If you have vomiting and/or diarrhea, inform your doctor immediately. Diarrhea causes the medication to be eliminated from the body without benefiting you. This may cause rejection of the transplanted organ. If necessary, the medication will be given to you intravenously in this case. It is also recommended that you avoid using laxatives during this period.
Store your medication in a dry place, at room temperature. Leaving it in direct sunlight, in the refrigerator, or in extreme heat or cold will cause it to lose its effectiveness. In addition, if you are using the liquid form, do not use medication that has been open for more than 60 days. You will need to have your cyclosporine levels in your blood checked regularly with blood tests. On the days of tests, it is recommended that you take your medication exactly as you are told and bring it with you. Be sure to have your blood level checked at the times your doctor tells you. For blood levels to give accurate results, be sure to take your medications regularly at the specified times. The medication dose is adjusted according to the cyclosporine level in the blood.
Do not take your medication with grapefruit juice. Grapefruit juice affects the blood level. Do not drink grapefruit juice for at least 2 hours before and 2 hours after the medication time. Some medications (such as ketoconazole and erythromycin) can greatly affect the cyclosporine level. Therefore, as mentioned before, even if another physician recommends it, be sure to ask your doctor before starting any medication. You can take your medication with milk or orange juice
Side effects
Cyclosporine can cause many side effects. Most commonly, it can cause hypertension. After you start taking the medication, your blood pressure should be measured regularly. If necessary, your doctor may recommend that you take blood pressure medications. Your blood cholesterol and triglyceride levels may also rise. Your kidney and liver function values may increase. For this reason, you need to have your laboratory tests done regularly. It may cause trembling of the hands, headache, leg cramps, gum swelling, and nausea and vomiting. In addition, your hair may become thicker and more irregular, and its shape and distribution may change somewhat.
Because long-term use can cause swelling of the gums, attention must be paid to oral hygiene. It is recommended that you brush your teeth after every meal and visit the dentist for a check-up every 4-6 months. Your dentist should also know that you are using this medication.
Be sure to report any side effects you experience to your doctor. Impairment of kidney function
Increased hair growth, nausea, vomiting, diarrhea and headache may be observed.
Remember that your problems will decrease over time as the medication doses are reduced
