Table of contents:

Rapamune, generically known as Sirolimus, is a prescription medication used as an immunosuppressive agent to prevent organ transplant rejection. Sirolimus works by blocking the activity of a protein called mammalian target of rapamycin (mTOR), which plays a key role in cell growth and proliferation. By inhibiting mTOR, sirolimus helps to reduce the number of immune cells that attack the transplanted organ, minimizing the risk of rejection. It is also indicated to treat a certain lung disease called lymphangioleiomyomatosis or LAM.

Uses and Dosage

Rapamune (Sirolimus) is available in tablet form and is typically taken orally once a day. You should decide whether to take Rapamune with or without a meal, and always follow this regimen for every dose. It is important to swallow the medication whole, and then drink a glass of water. Do not divide, crush, or chew the medication, as this is not recommended.

To achieve optimum results, take Rapamune regularly according to the prescribed dosing schedule. If you are also taking cyclosporine, make sure to take it 4 hours after Rapamune, as taking these medications at the same time could increase the levels of active ingredients in the system and potentially cause kidney problems.

Be sure not to change or adjust your Rapamune dosage, as it is determined based on several factors such as your weight, medical condition, laboratory test results, and response to treatment. It is also important not to stop taking Rapamune abruptly without first consulting your doctor to avoid any adverse effects or complications.
