What is Pennsaid?
Pennsaid (diclofenac) is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing substances in the body that cause pain and inflammation.
Pennsaid (diclofenac topical 1.5% solution) is used to treat pain in the knees caused by osteoarthritis. This medication may not be effective in treating arthritis pain elsewhere in the body.
Pennsaid may also be used for purposes not listed in this medication guide.
Diclofenac can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Do not use Pennsaid just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
Diclofenac may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Pennsaid, especially in older adults.
Before taking this medicine
Diclofenac can increase your risk of fatal heart attack or stroke, especially if you use it long term or take high doses, or if you have heart disease. Even people without heart disease or risk factors could have a stroke or heart attack while using Pennsaid.
Do not use Pennsaid just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
You should not use Pennsaid if you are allergic to diclofenac (Voltaren, Cataflam, Flector, and others), or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.
To make sure Pennsaid is safe for you, tell your doctor if you have:
heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;
a history of heart attack, stroke, or blood clot;
a history of stomach ulcers or bleeding;
liver or kidney disease;
Using Pennsaid during the last 3 months of pregnancy may harm the unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether diclofenac topical passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using Pennsaid.
Pennsaid is not approved for use by anyone younger than 18 years old.
How should I use Pennsaid?
Use Pennsaid exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use Pennsaid in larger amounts or for longer than recommended. Use the lowest dose that is effective in treating your condition.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Wash your hands after applying Pennsaid, unless you are treating the skin on your hands. Wait at least 10 minutes before dressing or wearing gloves. Wait at least 1 hour before you bathe or shower.
Do not apply Pennsaid to an open skin wound, or on areas of infection, rash, or burn. Do not cover treated skin with a bandage or expose it to heat from a hot tub, heating pad, or sauna. Heat or bandaging can increase the amount of diclofenac you absorb through your skin.
To treat osteoarthritis knee pain with Pennsaid: Apply the solution only to clean, dry skin. Spread the solution over the front, back, and sides of the knee. Wait until the solution is completely dry before covering treated skin with clothing or applying any other skin products, including sunscreen.
Store Pennsaid at room temperature away from moisture and heat. Do not freeze. Store Pennsaid in an upright position.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while using Pennsaid?
Do not use cosmetics, sunscreen, lotions, insect repellant, or other medicated skin products on the same area you treat with Pennsaid.
Avoid exposing treated skin to heat, sunlight, or tanning beds.
Avoid getting Pennsaid near your eyes, nose, or mouth. If this does happen, rinse with water. Call your doctor if you have eye irritation that lasts longer than 1 hour.
Avoid drinking alcohol. It may increase your risk of stomach bleeding.
Avoid taking aspirin or other NSAIDs while you are using Pennsaid.
Ask a doctor or pharmacist before using any cold, allergy, or pain medication. Many medicines available over the counter contain aspirin or other medicines similar to Pennsaid. Taking certain products together can cause you to get too much of this type of medication. Check the label to see if a medicine contains aspirin, ibuprofen, ketoprofen, or naproxen.
