Rapamune (sirolimus) is a prescription immunosuppressant used to help prevent the body from rejecting the organ that is transplanted, such as the kidneys. It is not a daily supplement but a powerful medicine that must be managed carefully. Under medical supervision, Rapamune helps your immune system tolerate a transplanted organ while minimizing overreaction. Due to its potency and risk profile, you’ll need regular lab tests and close follow-up to get the benefits safely.

Recommended Dosage of Rapamune for Transplant Patients
To use Rapamune safely and effectively:
Rapamune’s active ingredient, sirolimus, works by targeting a protein complex called mTOR (mechanistic Target Of Rapamycin). By doing so, it inhibits a chain of signals needed for immune cells (especially T-cells) to multiply and mount an aggressive response. In transplantation, this dampening effect helps prevent immune rejection of the graft (transplanted organ).
In LAM, sirolimus can slow the proliferation of abnormal smooth muscle–like cells in the lungs, helping stabilize lung function. Because it suppresses the immune response broadly, it must be balanced carefully to reduce the risk of infections and other side effects.
Note: Talk to your health care provider immediately if you notice signs of serious side effects.
Before and while using Rapamune, keep these critical cautions in mind:
To stay as safe as possible while using Rapamune:
If you miss or forget taking a Rapamune tablet, take it as soon as you remember that same day. If it’s really close to the time for your next dose, simply skip the missed dose and continue as scheduled. Do not take two tablets at once to make up for the missed one.
An overdose of Rapamune is rare under standard use. However, if someone ingests significantly more than prescribed and begins experiencing severe side effects, for example:
Seek urgent medical care or directly call 911. In more severe cases, contact poison control immediately at 1-800-222-1222 (toll-free).
To keep Rapamune stable and potent:
Rapamune may interact with several medications. It increases the risk of side effects or reduces effectiveness. Some important ones include:
Note: Always share a full list of medications (prescription and nonprescription) and supplements with your transplant team and pharmacist before starting Rapamune.
If Rapamune is not working for you, your transplant or treatment doctor may consider alternatives. Your next immunosuppressant may depend on your transplant type or condition:
