Consumer Medicine Information

What is in this leaflet

This leaflet answers some of the common questions about Diclofenac AN. 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 taking Diclofenac AN against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist. Keep this leaflet with the medicine. You may want to read it again.

What Diclofenac AN tablets are used for

The name of your medicine is Diclofenac AN. It contains the active ingredient diclofenac sodium.

Diclofenac AN is used for treating the symptoms of inflammatory and degenerative forms of rheumatism, rheumatoid arthritis and osteoarthritis. It is also used in conditions where back pain, muscle strains, sprains and tendonitis (e.g. tennis elbow) are observed. It is also used to relieve states of acute or chronic in which there is an inflammatory component, as well as for the symptomatic treatment of dysmenorrhoea (heavy, painful periods).

Your doctor may have prescribed Diclofenac AN for another reason. Ask your doctor if you have any questions about why Diclofenac AN was prescribed for you.

Diclofenac AN belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). It also has analgesic and antipyretic properties.

Diclofenac acts by reducing pain (at rest and on movement), morning stiffness and swelling of the joints associated with rheumatic diseases, as well as improving function.

In addition, it has been shown to relieve pain in dysmenorrhoea.

There is no evidence that Diclofenac AN is addictive.

Tell your doctor or pharmacist if you are currently taking a diuretic and other medicine(s) to help lower blood pressure at the same time. Sometimes diuretics and certain blood pressure lowering drugs are combined in the one product. If you are taking these drug combinations, your doctor may advise a blood test to check your kidney function before you start to take Diclofenac AN.

Take your dose as soon as you remember, and continue to take it as you would normally.

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

Do not take a double dose to make up for the dose you missed.

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