Sirolimus

Sirolimus may increase the risk that you will develop an infection or cancer, especially lymphoma (cancer of a part of the immune system) or skin cancer. To reduce your risk of skin cancer, plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen during your treatment. If you experience any of the following symptoms, call your doctor immediately: fever, sore throat, chills, frequent or painful urination, or other signs of infection; new sores or changes on the skin; night sweats; swollen glands in the neck, armpits, or groin; unexplained weight loss; trouble breathing; chest pain; weakness or tiredness that does not go away; or pain, swelling, or fullness in the stomach.

Sirolimus may cause serious side effects or death in patients who have had liver or lung transplants. This medication should not be given to prevent rejection of liver or lung transplants.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests to check your body’s response to sirolimus.

Talk to your doctor about the risks of taking sirolimus.

🔔 Why is this medication prescribed?

Sirolimus is used in combination with other medications to prevent rejection of kidney transplants. Sirolimus is in a class of medications called immunosuppressants. It works by suppressing the body’s immune system.

🔔 How should this medicine be used?

Sirolimus comes as a tablet and a solution (liquid) to take by mouth. It is usually taken once a day, either always with food or always without food. To help you remember to take sirolimus, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sirolimus exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

The problem isn’t a shortage of people wanting to be doctors, but rather, too few opportunities for training. Medical schools have increased class sizes by 30% since 2002, but federal funding for residency training – an essential step in the process of becoming a practicing physician – has not increased since 1997, according to Inside Higher Ed.

Swallow the tablets whole; do not split, chew, or crush them.

Your doctor will probably adjust your dose of sirolimus during your treatment, usually not more than once every 7 to 14 days.

Continue to take sirolimus even if you feel well. Do not stop taking sirolimus without talking to your doctor.

Sirolimus solution may develop a haze when refrigerated. If this happens, let the bottle stand at room temperature and gently shake it until the haze goes away. The haze does not mean that the medication is damaged or unsafe to use.

To use the bottles of solution, follow these steps:

1. Open the solution bottle. On first use, insert the plastic tube with stopper tightly into the bottle until it is even with the top of the bottle. Do not remove from the bottle once inserted.
2. For each use, tightly insert one of the amber syringes, with the plunger fully pushed in, into the opening in the plastic tube.
3. Draw up the amount of solution your doctor has prescribed by gently pulling out the plunger of the syringe until the bottom of the black line of the plunger is even with the correct mark on the syringe. Keep the bottle upright. If bubbles form in the syringe, empty the syringe into the bottle and repeat this step.
4. Empty the syringe into a glass or plastic cup containing at least 2 ounces (60 milliliters [1/4 cup]) of water or orange juice. Do not use apple juice, grapefruit juice, or other liquids. Stir vigorously for 1 minute and drink immediately.
5. Refill the cup with at least 4 ounces (120 milliliters [1/2 cup]) of water or orange juice. Stir vigorously and drink the rinse solution.
6. Dispose of the used syringe.

If you need to carry a filled syringe with you, snap a cap onto the syringe and put the syringe in the carrying case. Use the medication in the syringe within 24 hours.

🔔 What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store tablets at room temperature and away from light, excess heat, and moisture (not in the bathroom). Keep liquid medication in the refrigerator, away from light, closed tightly, and dispose of any unused medication one month after the bottle is opened. Do not freeze. If needed, you may store the bottles for up to 15 days at room temperature.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

🔔 In case of emergency/overdose

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can’t be awakened, immediately call emergency services at 911.

🔔 What other information should I know?

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
