What Rapamune is used for

Rapamune belongs to a group of medicines called immunosuppressants. It helps to control your body's immune system after you have received an organ transplant. It is used to prevent your body from rejecting the transplanted kidney. Rapamune is not recommended for patients who have received liver or lung transplants.

Your doctor may have prescribed Rapamune for another reason. Ask your doctor if you have any questions about why Rapamune has been prescribed for you.

Rapamune is not recommended for use in children, as there is limited information available on its effects in children.

This medicine is available only with a doctor's prescription.

Rapamune is not habit-forming.

How to take Rapamune

Rapamune is for oral use only.

Always take the medicine exactly as your doctor tells you.

How much to take

Your doctor will decide exactly what dose of Rapamune you must take and how often to take it.

Follow your doctor's instructions exactly and never change the dose yourself. Do not stop taking your medicine unless your doctor tells you to.

The usual starting dose is 6 mg after transplantation and then 2 mg once daily. You will also need to take medicines such as ciclosporin and corticosteroids.

After 2 to 4 months, your doctor will start reducing the dose of ciclosporin you take and increasing your dose of Rapamune. Eventually your ciclosporin will be completely stopped. Your doctor will determine how much Rapamune you need to take.

Follow all directions given to you by your doctor and pharmacist carefully.

These directions may differ from the information contained in this leaflet.

If you do not understand the instructions on the bottle, ask your doctor or pharmacist for help.

How to take Rapamune

Take Rapamune consistently, either with or without food. Do not take Rapamune with grapefruit juice.

Follow these instructions to prepare Rapamune for use:

1.Remove the safety cap from the bottle by squeezing the tabs on the cap and twisting counter clockwise. The first time you use a bottle of Rapamune Oral Solution, insert the syringe adaptor into the bottle until it is flush with the top of the bottle. Do not attempt to remove the syringe adaptor from the bottle once inserted.

2.Use a new dosing syringe for each does of Rapamune Oral Solution. With the plunger fully depressed, insert one of the dosing syringes into the opening in the adaptor.

3.Withdraw the exact amount of Rapamune as prescribed by your doctor by gently pulling out the plunger of the dosing syringe until the level of the oral solution is even with the mark on the dosing syringe for the prescribed dose. The bottle should remain in an upright position when withdrawing the solution. If bubbles form in the dosing syringe during withdrawal, empty the Rapamune solution back into the bottle and repeat the withdrawal procedure.

4.You may have been instructed to take your Rapamune oral solution at a particular time of day. If it is necessary to carry your medication with you, place a cap securely on the dosing syringe - the cap should snap into place. Then place the capped dosing syringe in the carrying case provided. Once in the syringe the medication may be kept at room temperature or refrigerated and used within 24 hours.

5.Empty the contents of the dosing syringe into a glass or plastic cup containing at least 60 mL of water or orange juice. Stir quickly for one minute and drink at once.

6.When mixed with water or orange juice Rapamune produces a white to off-white mixture.

7.Refill the glass or plastic cup with at least 120 mL of water or orange juice, stir quickly, and drink at once.

Do NOT use any liquids other than water or orange juice for dilution. Only use a glass or plastic cup to dilute Rapamune, and drink the preparation immediately after dilution. Use the dosing syringe and syringe cap once only and then discard.


When refrigerated the solution in the bottle may separate or appear hazy. If this occurs, bring your Rapamune oral solution to room temperature and shake gently. The presence of a haze does not affect the quality of Rapamune.

When to take Rapamune

Take Rapamune once a day at about the same time each day.

Taking Rapamune at the same time each day will have the best effect. It will also help you remember when to take it.

If you are also taking ciclosporin, then you must take Rapamune 4 hours after your ciclosporin dose.

How long to take Rapamune

You will need to take Rapamune for the rest of your life, or until your doctor decides to change your immunosuppressive medication.

If you forget to take Rapamune

If it is almost time for your next dose (within 4 hours), skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for the dose that you missed and always take Rapamune and ciclosporin approximately 4 hours apart.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (tel. 13 11 26 in Australia or 0800 764 766 in New Zealand), or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Rapamune. Do this even if there are no signs of discomfort or poisoning. Take the labelled medicine bottle with you, even if it is empty.

You may need urgent medical attention. If you take too much Rapamune, your heart may start beating abnormally.

While you are using Rapamune

Things you must do

Tell any other doctors, dentists and pharmacists who are treating you that you are taking Rapamune.

Attend all doctor's appointments to monitor your condition.

Your doctor needs to closely monitor the level of Rapamune found in your blood to make sure the dose you are taking is best for your condition.

Take any antibiotic medication for as long as your doctor prescribes them.

Taking antibiotics helps prevent getting an infection.

Things you must not do

Do not give Rapamune to anyone else even if they have the same condition as you.

Do not use Rapamune to treat any other complaints unless your doctor tells you to.

Do not stop taking Rapamune, or change the dosage, without checking with your doctor.

Kidney transplant patients need to remain on immunosuppressive medication.

Things to be careful of

Limit your exposure to sunlight and UV light by wearing protective clothing and using a sunscreen with a high protection factor.

Immunosuppressive drugs such as Rapamune may increase the risk of developing cancer of the lymph glands and skin.

If you develop new lumps, spots or moles anywhere on your body, or you notice changes in existing lumps, spots or moles, tell your doctor.

This may be a sign of cancer. Immunosuppressant medicines, including Rapamune, may increase the risk of developing certain cancers, including skin cancer and lymphoma (cancer of the lymphatic system).

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Rapamune. Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

Side Effects

Check with your doctor as soon as possible if you have any problems while taking Rapamune, even if you do not think the problems are connected with the medicine or are not listed in this leaflet.

If you get any side effects, do not stop taking Rapamune without first talking to your doctor.

Rapamune helps most people with kidney transplants but it may have unwanted side effects. However, since Rapamune is often taken in combination with other medicines, Rapamune may not have necessarily caused the side effects.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Unwanted side effects that you may not be aware of whilst taking Rapamune include an increase in blood pressure and changes in the levels of red or white blood cells or substances carried in your blood (e.g. fat, cholesterol, protein, potassium or liver enzymes). During treatment your doctor may do blood tests to measure these changes.

Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything that is making you unwell.

Do not be alarmed by this list of possible side effects. You may not experience any of them.
