About topical diclofenac

Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) and works by preventing the production of irritant chemicals which cause pain and inflammation. It is used topically (which means it is applied to the skin) to ease muscular pains, sprains and strains. A topical diclofenac preparation called Solaraze® gel is used to treat a condition called actinic keratosis (skin damage caused by sun exposure). This preparation is a different strength to that used for pain relief, and the two types of topical diclofenac are not interchangeable.

Before using topical diclofenac

Before using diclofenac topical make sure your doctor or pharmacist knows:

• If you are pregnant or breast-feeding.
• If you have asthma or breathing problems.
• If you have ever had an unusual reaction after taking aspirin or a non-steroidal anti-inflammatory drug (NSAID) such as indometacin, ibuprofen or naproxen, or any other medicine.
• If your skin is inflamed or broken.
• If you have severe kidney problems.
• If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.

How to use topical diclofenac

• Before beginning treatment, read the manufacturer's printed information leaflet.
• Apply a thin layer and gently massage it into the affected area. Wash your hands well afterwards.
• Your doctor or pharmacist will recommend how often and for how long to use topical diclofenac, but for strains and sprains this is usually three or four times a day for no more than 2 weeks unless on your doctor's advice.
• If you are using diclofenac gel to treat actinic keratosis, it should be applied thinly to the affected area twice daily for 60-90 days.
• Do not use topical diclofenac near your eyes, inside your nose, or let it come into contact with any inflamed or broken skin.
