There are simple treatment options available for symptoms of knee OA. Among the most commonly used medications are NonSteroidal Anti-Inflammatory Drugs, or NSAIDs.
- NSAIDs are a class of medicines that treat the pain and inflammation of some medical conditions
YOU HAVE A CHOICE IN TREATMENT.
Some NSAIDs are taken orally and others are applied topically.
- Oral medications are generally released in the stomach and then go into your bloodstream
- As a result, a larger amount of the medicine goes through your whole body than it would with a topical medicine.
- A topical medication is applied to the skin
- Topical treatments allow you to apply the medication directly to your knee
All NSAIDs, including oral, topical, and even nonprescription versions, such as ibuprofen, or naproxen,
pose serious risk of cardiovascular and gastrointestinal side effects.
- Studies suggest that topical NSAIDs may offer safety benefits for the stomach and intestines compared to oral NSAIDs in some patients

ASK YOUR DOCTOR IF PENNSAID® TOPICAL NSAID SOLUTION IS RIGHT FOR YOU.
Tell your doctor about all of your symptoms and if your knee OA pain interferes with everyday activities. Only you and your doctor can decide if PENNSAID is right for you.
