Consumer Medicine Information

What is in this leaflet

Please read this leaflet carefully before being treated with DEPO-MEDROL suspension for injection. This leaflet answers some common questions about DEPO-MEDROL. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you being treated with DEPO-MEDROL against the benefits this medicine is expected to have for you.

If you have any concerns about this medicine, ask your doctor or pharmacist.

Consider keeping this leaflet even after treatment with DEPO-MEDROL is finished. You may need to read it again.

What DEPO-MEDROL is used for

DEPO-MEDROL is used to treat disorders of many organ systems such as skin, lung, eye, gastrointestinal tract, nervous system, joints and blood. DEPO-MEDROL works by reducing inflammation and changing the body’s natural ability to respond when the immune response is not working properly. It is also used in certain conditions where the adrenal gland doesn’t function correctly.

Your doctor may have prescribed DEPO-MEDROL for another reason.

Ask your doctor if you have any questions about why DEPO-MEDROL has been prescribed for you.

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

Treatment with DEPO-MEDROL

This medicine will be administered under medical supervision.

It may be given into a muscle (intramuscularly) or into a joint (intra-articularly) or into a lesion (intralesional). Due to the risk of serious side effects, it must not be injected into the spinal cord (intrathecally or epidural) or into a vein (intravenously).

How and where DEPO-MEDROL is injected and the dose given will depend on the nature and the severity of your condition. You will be given a different dosage depending on your condition and how you react to the medicine.

If you are given too much (overdose)

Overdose is unlikely with DEPO-MEDROL. However, repeated frequent doses over a long period of time may cause an increase in side effects.

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency (Casualty) at your nearest hospital if you think that you or anyone else may have been given too much DEPO-MEDROL. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. Keep the telephone numbers for these services handy. Have the DEPO-MEDROL box or this leaflet available to give details if needed.

Your doctor may reduce the dose of DEPO-MEDROL gradually if you have been on long-term treatment.
