How to Take Rapamune Oral Solution
Rapamune is for oral use only and must be taken exactly as prescribed by your doctor. The medication requires specific preparation steps and timing.
Dosage Instructions
The usual starting dose is 6 mg after transplantation, then 2 mg once daily. You will also take other medicines like ciclosporin and corticosteroids. After 2-4 months, your doctor will reduce ciclosporin and increase Rapamune until ciclosporin is completely stopped. Take consistently with or without food at the same time each day. If taking ciclosporin, take Rapamune 4 hours after your ciclosporin dose. Follow detailed preparation steps: use new dosing syringe each time, withdraw exact prescribed amount, mix with at least 60 mL of water or orange juice, stir and drink immediately, then rinse cup with 120 mL more liquid and drink again. Do not use grapefruit juice.
What If You Miss a Dose?
If it’s almost time for your next dose (within 4 hours), skip the missed dose and take your next dose as scheduled. Otherwise, take it as soon as you remember, then return to your normal schedule. Always keep Rapamune and ciclosporin approximately 4 hours apart.
Important: Never take a double dose to make up for a missed dose. You will need to take Rapamune for the rest of your life or until your doctor changes your medication.
