WHAT DICLOFENAC INJECTION IS AND WHAT IT IS USED FOR
• Diclofenac Injection is provided as an injection solution, containing 75 mg Diclofenac
sodium in 3 ml, to be given by intramuscularly ( into a muscle) or intravenously (into a vein) as an infusion
• Each ampoule contains 75mg diclofenac sodium. The ampoules are packaged in a carton, and
10 ampoules are in each carton.
• Diclofenac is a non-steroidal anti-inflammatory drug (NSAID). NSAIDs are prescribed for
adults and the elderly for treatment of painful conditions, such as kidney stone pain,
osteoarthritis (degeneration of joints) and rheumatoid arthritis (inflammation of joints), back
pain, gout (formation of crystals in joints), injuries and fractures.
BEFORE YOU HAVE DICLOFENAC INJECTION.
You must NOT have Diclofenac Injection:
• if you are allergic to Diclofenac or any of the contents of this medicine (listed above)
• you have now, or have ever had, a stomach (gastric) or duodenal (peptic) ulcer, or bleeding in
the digestive tract (this can include blood in vomit, bleeding when emptying bowels, fresh blood
in stools or black, tarry stools)
• If you have had any allergic reaction to ibuprofen, aspirin, or other NSAIDs (including difficulty in breathing, runny nose, swelling of the face or throat, or rash)
• if you have asthma
• if you have kidney or liver problems.
• if you are dehydrated or have recently lost a lot of blood
• if you have severe heart failure
• if you have a condition where you don’t stop bleeding normally (such as haemophilia)
• if you have had a stroke
Take special care with Diclofenac Injection
• Do you suffer from stomach or bowel disorders, including ulcerative colitis or Crohn’s disease?
• Do you have kidney, liver or heart problems, or are you elderly?
• Do you have lupus (SLE) or any similar condition?
• Do you suffer from a condition called porphyria?
If the answer to any of these questions is YES, discuss your treatment with your doctor or
pharmacist because Diclofenac injection might not be the right medicine for you.
Make sure your doctor knows, before you are given diclofenac
• If you smoke
• If you have diabetes
• If you have angina, blood clots, high blood pressure, raised cholesterol or raised triglycerides
Side effects may be minimised by using the lowest effective dose for the shortest duration
If you have a history of stomach problems when you are taking NSAIDs, particularly if you are
elderly, you must tell your doctor straight away if you notice any unusual symptoms.
Because it is an anti-inflammatory medicine, diclofenac may reduce the symptoms of
infection, for example, headache and high temperature. If you feel unwell and need to see a
doctor, remember to tell him or her that you are taking diclofenac.
If you have heart, kidney or liver problems, or having medicines to increase urine volume such
as diuretics or you are elderly, your doctor may monitor your kidney function.
Diclofenac injection should not be used in children.
Taking/using other medicines
Some medicines can interfere with your treatment. Tell your doctor or pharmacist if you are taking any of the following:
• Digoxin (used to treat heart problems)
• Medicines to treat diabetes
• Oral steroids (an anti-inflammatory drug)
• Lithium (used to treat mental illness)
• Antibiotics called quinolones (such as ciprofloxacin)
• Cyclosporin and tacrolimus (used to treat some inflammatory diseases and after transplants)
• Methotrexate (used for some inflammatory diseases and cancers)
• Drugs that can increase your risk of bleeding, sometimes given if you have heart problems,
such as dipyridamole or clopidogrel
• Some medicines for depression, such as paroxetine or fluoxetine
• Diuretics (water tablets)
• Medicines to treat high blood pressure
• Diclofenac may make it more difficult to become pregnant. You should inform your doctor if
you are planning to become pregnant or if you have problems becoming pregnant.
• If you are pregnant, or think you may be pregnant, you must not receive Diclofenac
Injection unless your doctor advises it. However, diclofenac must never be given in the last three
months of pregnancy
• If you are breast-feeding you must not receive Diclofenac Injection.
Driving and using machinery
• Diclofenac may make you feel drowsy or dizzy, or cause problems with vision. If you are
affected, do not drive or operate machinery.
• The elderly have increased frequency of adverse reactions to NSAIDs especially gastro
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
as oral, corticosteroids, anticoagulants such as warfarin, selective serotonin-reuptake inhibitors
(SSRIs) or anti-platelet agents such as aspirin.
HOW TO TAKE DICLOFENAC INJECTION
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.
If you have more Diclofenac Injection than you should:
If you think you have been given too much, tell your doctor or nurse straight away.
