Diclofenac Gel

If you've dealt with osteoarthritis pain in the past, you may be familiar with diclofenac. Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) and it falls in the same class as drugs such as ibuprofen, naproxen and aspirin. Diclofenac eases pain and reduces inflammation like other NSAID medications. It works by blocking the production of certain enzymes in our body called COX1 and COX2. These enzymes are responsible for the production of chemicals called prostaglandins which cause pain and inflammation. So, when you block the production of COX 1 and 2, you reduce the production of prostaglandins, resulting in less pain and inflammation.¹
