Summary
Sirolimus is used to prevent organ rejection after a transplant, which is when the body attacks a new organ. It is also sometimes used to treat certain types of cancer.
Sirolimus works by suppressing the immune system, which helps the body accept a new organ. It does this by inhibiting a protein called mTOR, which is involved in cell growth and immune response.
The usual starting dose for adults is 2 mg once daily, with a maximum of 5 mg daily. It is taken orally, either in the morning or evening, and should be taken consistently with or without food.
Common side effects include high blood pressure, high cholesterol, and an increased risk of infections. These effects vary among individuals and should be monitored by a doctor.
Sirolimus can increase infection risk and affect kidney function. It should not be used by those allergic to it or with severe liver problems. Regular blood tests are crucial to monitor health while on this medication.
