Drug information provided by: Micromedex
Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. The exact amount of medicine you need has been carefully worked out. Using too much will increase the risk of side effects, while using too little may lead to rejection of your transplanted kidney.
This medicine usually comes with patient information or directions. Read them carefully and make sure you understand them before taking this medicine. If you have any questions, ask your doctor.
To help you remember to take your medicine, try to get into the habit of taking it at the same time each day. This will help sirolimus work better by keeping a constant amount in the blood.
You may take this medicine with or without food. However, you should take it the same way (with or without food) each time.
Grapefruits and grapefruit juice may increase the effects of sirolimus by increasing the amount of this medicine in your body. You should not eat grapefruit or drink grapefruit juice while you are taking this medicine.
Do not stop taking this medicine without checking first with your doctor. You may have to take this medicine for the rest of your life to prevent your body from rejecting the transplant.
Sirolimus is usually used along with a corticosteroid (cortisone-like medicine) and cyclosporine (immunosuppressive agent). Sirolimus should be taken 4 hours after cyclosporine modified oral solution (Neoral®) or cyclosporine modified capsules (Neoral®). If you have any questions about this, ask your doctor.
If you have been taking sirolimus together with cyclosporine for 2 to 4 months after your transplant, your doctor may want you to stop using cyclosporine and increase the dose of sirolimus. However, some patients (e.g., black patients or those with transplant rejection in the past) may need to continue using cyclosporine for up to one year after the transplant. Your doctor will tell you if you need to keep taking cyclosporine.
Sirolimus tablets should not be crushed, chewed, or split. If you are unable to take the tablet form, your doctor will give you an oral liquid and be given instructions on how to take it.
To use the oral liquid:
Open the solution bottle and insert the adapter tightly into the bottle.
Insert the amber syringe (plastic needle) that comes with the bottle to draw the right amount of medicine out of the bottle.
Empty the medicine from the syringe into a glass or plastic cup.
Mix the medicine with at least 2 ounces (¼ cup or 60 milliliters [mL]) of water or orange juice. Stir the mixture well and drink it immediately.
Add at least 4 ounces (½ cup or 120 mL) of additional water or orange juice, stir it well, and drink it to make sure that all of the medicine is taken.
If you have been instructed by your doctor to carry your medicine, you may keep your daily dose of sirolimus in a tightly-capped syringe for a maximum of 24 hours at room temperature or in the refrigerator. Throw away the used syringe after each use.
If this medicine gets into your skin, wash it with soap and water right away. If it gets in your eyes, rinse them with water.
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
