Senior Health Home > Diclofenac Sodium Topical Solution Information

A prescription arthritis medication, diclofenac sodium topical solution (Pennsaid®) helps relieve pain and other symptoms of osteoarthritis of the knee. It belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs), which means it works by blocking the production of various inflammatory substances in the body. At this time, the medicine is available in brand-name form only.
The medication is typically applied to the skin four times a day, and should be applied 10 drops at a time, either directly onto the knee or into a hand first, in order to help prevent spillage. This process is repeated until the total recommended number of drops has been reached. Although most people tolerate it well, side effects can occur with diclofenac sodium topical solution. Based on information gathered in clinical trials, the most common problems reported with the product are skin reactions at the application site.
