Acts through cyclo-oxygenase-2 (COX-2) inhibition, striking inflammation at its source
Learn how diclofenac reduces inflammation by inhibiting prostaglandin biosynthesis through action on the COX enzymes with selectivity for COX-2, and inhibiting phospholipase A2 activity to reduce the production of inflammatory leukotrienes.1
Diclofenac is a potent anti-inflammatory agent1
Its effect on the COX-2 enzyme means that, unlike non-NSAID medications such as paracetamol, diclofenac not only provides pain relief but also reduces inflammation – a root cause of pain.
Diclofenac, an NSAID (and therefore in the same drug class as ketoprofen and ibuprofen), shows marked potency in its inhibition of the COX-2 enzyme.3

Pregnancy and lactation: The systemic concentration of diclofenac is lower after topical administration, compared to oral formulations. During the first and second trimester of pregnancy, diclofenac should not be given unless clearly necessary. Only use during lactation on the advice of a health professional. Contraindicated during the third trimester of pregnancy. Should not be applied on the breasts of nursing mothers, nor elsewhere on large areas of skin or for a prolonged period of time.
