What is in this leaflet
This leaflet answers some common questions about ENDONE. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed up the risks of you taking ENDONE against the benefits they expect it will have for you.

What ENDONE is used for
This medicine contains oxycodone hydrochloride as the active ingredient.
ENDONE belongs to a group of medicines called narcotic analgesics. Narcotic analgesics act to relieve pain.
Ask your doctor if you have any questions about why ENDONE has been prescribed for you. Your doctor may have prescribed it for another reason.
ENDONE is only available with a doctor’s prescription.
ENDONE can be addictive. If used for a long time ENDONE may become habit forming causing mental and physical dependence. If abused it may become less able to reduce pain.
