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.
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.
