What is Pennsaid?
Pennsaid is a topical prescription medicine used to treat pain from osteoarthritis, applied directly to the affected area. The best-known version contains the nonsteroidal anti-inflammatory drug (NSAID) diclofenac in a liquid/solution form.
What does “Pennsaid” treat?
Pennsaid is used for osteoarthritis pain, typically in joints such as the knees and hands, depending on the specific product and how it’s prescribed.
How is Pennsaid used (and how often)?
Usage depends on the exact Pennsaid formulation your clinician prescribes (the dosing schedule can differ by product strength). In general, it’s applied to clean, intact skin over the affected joint and allowed to dry before covering or using the area—following the specific directions on your prescription label.
What are common side effects?
Because Pennsaid is a topical NSAID, side effects are often related to the skin where it’s applied, such as redness, irritation, or burning. Systemic NSAID effects are possible but generally lower than with oral NSAIDs because less drug reaches the bloodstream when used topically.
Who should avoid Pennsaid?
Patients are usually advised to avoid topical NSAIDs like diclofenac if they have had NSAID-related allergic reactions, have certain asthma/aspirin sensitivity histories, or if they have significant skin issues (for example, open wounds) at the application site. Your prescriber can assess your risk based on your medical history and other medications.
Pennsaid vs. other diclofenac topical products
Pennsaid is one brand of diclofenac topical therapy; other diclofenac products may differ by formulation (solution vs. gel/cream), dosing frequency, and prescription labeling. If you tell me the exact product strength on your box (for example, “Pennsaid 1.5%”), I can help you compare it with the closest alternatives.
