intestinal bleeding and perforation which may be fatal. Caution should be advised in patients
receiving concomitant medications which could increase the risk of ulceration or bleeding, such

Your doctor will decide when and how to treat you with Diclofenac Injection. You will either be
given an intravenous infusion (a drip into a vein) or an intramuscular injection (an injection into
a muscle). The intramuscular injection is usually injected into the buttocks.
The usual dose is:
One or two ampoules (75 to 150 mg) each day for one or two days.
Your doctor may give you a dose that is lower than the usual adult dose if you are elderly.
Not suitable for children.
A doctor, nurse or pharmacist will prepare the injection for you. If you have had an operation
and are in hospital, the ampoule contents may be diluted and put into a drip bag before being
given to you. A nurse or doctor will usually then give you the injection or infusion. You would
not usually have to give the injection to yourself.
The doctor may also prescribe another drug to protect the stomach to be taken at the same time,
particularly if you have had stomach problems before, or if you are elderly, or taking certain
other drugs as well.
