Sirolimus (Oral route)
Increased susceptibility to infection and the possible development of lymphoma and other malignancies may result from immunosuppression. Only physicians experienced in immunosuppressive therapy and management of renal transplant patients should prescribe sirolimus, and they should have complete information requisite for the follow-up of the patient. The use of sirolimus in combination with cyclosporine or tacrolimus was associated with excess mortality, graft loss, and hepatic artery thrombosis in studies in de novo liver transplant patients. Cases of bronchial anastomotic dehiscence, most fatal, have been reported in de novo lung transplant patients when sirolimus has been used as part of an immunosuppressive regimen. The safety and efficacy of sirolimus as immunosuppressive therapy have not been established in liver or lung transplant patients, and therefore, such use is not recommended .
Uses of This Medicine:
Sirolimus belongs to a group of medicines known as immunosuppressive agents. It is used to lower the body's natural immunity in patients who receive kidney transplants.
When a patient receives an organ transplant, the body's white blood cells will try to get rid of (reject) the transplanted organ. Sirolimus works by preventing the white blood cells from getting rid of the transplanted organ.
Sirolimus is a very strong medicine. It can cause side effects that can be very serious, such as kidney problems. It may also reduce the body's ability to fight infections. You and your doctor should talk about the benefits of this medicine as well as the risks.
This medicine is available only with your doctor's prescription.
Before Using This Medicine:
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of sirolimus in children younger than 13 years of age or in children considered to be at high immunologic risk. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of sirolimus in the elderly. However, elderly patients are more likely to have liver and heart problems, which may require caution in patients receiving sirolimus.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Proper Use of This Medicine:
Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. The exact amount of medicine you need has been carefully worked out. Using too much will increase the risk of side effects, while using too little may lead to rejection of your transplanted kidney.
This medicine usually comes with patient information or directions. Read them carefully and make sure you understand them before taking this medicine. If you have any questions, ask your doctor.
To help you remember to take your medicine, try to get into the habit of taking it at the same time each day. This will help sirolimus work better by keeping a constant amount in the blood.
You may take this medicine with or without food. However, you should take it the same way (with or without food) each time.
Grapefruits and grapefruit juice may increase the effects of sirolimus by increasing the amount of this medicine in your body. You should not eat grapefruit or drink grapefruit juice while you are taking this medicine.
Do not stop taking this medicine without checking first with your doctor. You may have to take this medicine for the rest of your life to prevent your body from rejecting the transplant.
Sirolimus is usually used along with a corticosteroid (cortisone-like medicine) and cyclosporine (immunosuppressive agent). Sirolimus should be taken 4 hours after cyclosporine modified oral solution (Neoral®) or cyclosporine modified capsules (Neoral®). If you have any questions about this, ask your doctor.
If you have been taking sirolimus together with cyclosporine for 2 to 4 months after your transplant, your doctor may want you to stop using cyclosporine and increase the dose of sirolimus. However, some patients (e.g., black patients or those with transplant rejection in the past) may need to continue using cyclosporine for up to one year after the transplant. Your doctor will tell you if you need to keep taking cyclosporine.
Sirolimus tablets should not be crushed, chewed, or split. If you are unable to take the tablet form, your doctor will give you an oral liquid and be given instructions on how to take it.
To use the oral liquid:
If this medicine gets into your skin, wash it with soap and water right away. If it gets in your eyes, rinse them with water.
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
Store the oral tablets at room temperature in a closed container, away from heat, moisture, and direct light.
Store the oral liquid in the refrigerator. Protect it from direct light and moisture. Do not freeze. You may store the oral liquid at room temperature for a short period of time (not more than 15 days). If you see a slight haze or cloudiness in the bottle, leave it out at room temperature and shake it until the haze disappears. Throw away any unused medicine after 30 days.
Precautions While Using This Medicine:
It is very important that your doctor check the progress of you or your child at regular visits to make sure that this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.
Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant, and keep using it for at least 12 weeks after you stop taking sirolimus. If you think you have become pregnant while using the medicine, tell your doctor right away.
While you are taking sirolimus, it is important to maintain good dental hygiene and see a dentist regularly for teeth cleaning.
Raw oysters or other shellfish may contain bacteria that can cause serious illness and possibly death. This is more likely to be a problem if these foods are eaten by patients with certain medical conditions. Even eating oysters from “clean” water or good restaurants does not guarantee that the oysters do not contain the bacteria. Eating raw shellfish is not a problem for most healthy people; however, patients with the following conditions may be at greater risk: cancer, immune disorders, organ transplantation, long-term corticosteroid use (as for asthma, arthritis, or organ transplantation), liver disease (including viral hepatitis), excess alcohol intake (2 to 3 drinks or more per day), diabetes, stomach problems (including stomach surgery and low stomach acid), and hemochromatosis (an iron disorder). Do not eat raw oysters or other shellfish while you are taking sirolimus. Be sure oysters and shellfish are fully cooked.
While you are being treated with sirolimus, and after you stop treatment with it, it is important to see your doctor about the immunizations (vaccinations) you should receive. Do not get any immunizations without your doctor's approval. Sirolimus may lower your body's resistance and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your household should not take oral polio vaccine since there is a chance they could pass the polio virus on to you. Also, avoid other persons who have taken the oral polio vaccine. Do not get close to them, and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.
Treatment with sirolimus may increase the chance of getting other infections. If you can, avoid people with colds or other infections. If you think you or your child are getting a cold or other infection, check with your doctor.
This medicine may also increase your risk of bleeding and cause delay in wound healing. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Brush and floss your teeth gently. Be careful when using sharp objects, including razors and fingernail clippers. Check with your doctor immediately if you or your child notice any unusual bleeding or bruising; black, tarry stools; blood in the urine or stools; or pinpoint red spots on your skin.
Sirolimus may cause serious types of allergic reactions, especially when used with certain medicines. Tell your doctor right away if you or your child have a rash; itching; large, hive-like swelling on the face, eyelids, lips, tongue, throat, hands, legs, feet, or sex organs; red, swollen skin; trouble with breathing; or chest tightness while you are using this medicine.
Sirolimus may cause you to have a greater risk for getting cancer, especially skin cancer or cancer of the lymph glands (lymphoma). When you or your child begin taking this medicine:
This medicine may increase your cholesterol and fats in the blood. If this condition occurs, your doctor may give you or your child some medicines that can lower the amount of cholesterol and fats in the blood.
This medicine may increase your risk of developing a rare and serious virus infection called BK virus-associated nephropathy (BKVAN). The BK virus may affect how your kidneys work and cause a transplanted kidney to fail. Check with your doctor right away if you or your child are having more than one of these symptoms: bloody urine; a decreased frequency or amount of urine; increased thirst; loss of appetite; lower back or side pain; nausea; swelling of the face, fingers, or lower legs; trouble with breathing; unusual tiredness or weakness; vomiting; or weight gain.
This medicine may increase your risk of developing a serious and rare brain infection called progressive multifocal leukoencephalopathy (PML). Check with your doctor right away if you or your child are having more than one of these symptoms: vision changes, loss of coordination, clumsiness, confusion, memory loss, difficulty speaking or understanding what others say, and weakness in the legs.
Check with your doctor right away if you notice a new mole; a change in size, shape or color of an existing mole; or a mole that leaks fluid or bleeds.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
