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:
- Stay out of direct sunlight, especially between the hours of 10:00 a.m. and 3:00 p.m., if possible.
- Wear protective clothing, including a hat. Also, wear sunglasses.
- Apply a sunblock product that has a skin protection factor (SPF) of at least 15. Some patients may require a product with a higher SPF number, especially if they have a fair complexion. If you have any questions about this, check with your doctor.
- Apply a sun block lipstick that has an SPF of at least 15 to protect your lips.
- Do not use a sunlamp or tanning bed or booth.

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.
