Pennsaid solution is a nonsteroidal anti-inflammatory drug (NSAID). It may cause an increased risk of serious and sometimes fatal heart and blood vessel problems (eg, a heart attack, stroke). The risk may be greater if you already have heart problems or if you use Pennsaid solution for a long time. Do not use Pennsaid solution right before or after bypass heart surgery.
Pennsaid solution may cause an increased risk of serious and sometimes fatal stomach ulcers and bleeding. Elderly patients may be at greater risk. This may occur without warning signs.
Pennsaid solution is used for:
Treating pain in the knee joints caused by osteoarthritis. It may also be used for other conditions as determined by your doctor.
Pennsaid solution is an NSAID. Exactly how it works is not known. It may work by blocking certain substances in the body that are linked to inflammation. NSAIDs treat the symptoms of pain and inflammation. They do not treat the disease that causes those symptoms.
Do NOT use Pennsaid solution if:
- you are allergic to any ingredient in Pennsaid solution
- you have had a severe allergic reaction (eg, severe rash, hives, trouble breathing, growths in the nose, dizziness) to aspirin or another NSAID (eg, celecoxib, ibuprofen)

- you have severe kidney problems
