What is Pennsaid?
Pennsaid contains diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing hormones that cause inflammation and pain in the body.
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.
You should not use Pennsaid if you have ever had asthma or a severe allergic reaction caused by aspirin, diclofenac (Cataflam, Voltaren), or another nonsteroidal anti-inflammatory drug (NSAID).
NSAIDs may increase your risk of heart attack or stroke, especially if you use it long term or have heart disease. Do not use Pennsaid just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
NSAIDs may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Pennsaid.
Before taking this medicine
You should not use Pennsaid if you have ever had asthma or a severe allergic reaction caused by aspirin, diclofenac (Cataflam, Voltaren), or another NSAID.
While the risk of absorbing diclofenac into your bloodstream is low, an NSAID may increase your risk of heart attack or stroke, especially if you use it long term or have heart disease. Do not use Pennsaid just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
An NSAID may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Pennsaid, especially if:
you are in poor health;
you smoke or drink alcohol;
you are an older adult;
you use Pennsaid long-term; or
you take a blood thinner (warfarin, Coumadin) or steroid medicine (prednisone, dexamethasone, and others).
To make sure Pennsaid is safe for you, tell your doctor if you have:
a history of drug allergies;
a history of heart attack, stroke, or blood clot;
heart disease, congestive heart failure, high blood pressure;
a history of stomach ulcer or bleeding;
liver or kidney disease;
a bleeding or blood clotting disorder; or
asthma, or polyps in your nose.

How should I use Pennsaid?
Use Pennsaid exactly as prescribed by your doctor. Follow all directions on your prescription label. Keep using any oral medications your doctor has prescribed.
Wash your hands after applying this medication, unless you are treating the skin on your hands.
Do not use Pennsaid on an open skin wound, or on areas of eczema, infection, skin rash, or burn injury. Do not cover the treated skin with a bandage or expose it to heat from a hot tub, heating pad, sauna, or heated water bed. Heat or bandaging can increase the amount of drug you absorb through your skin and may cause harmful effects.
Before you use Pennsaid for the first time, you will need to prime the pump. To prime the pump, remove the cap and fully press the top of the pump all the way down 4 times while holding the bottle in an upright position. Dispense this portion of the medicine into a tissue or paper towel and throw it away in a trash can. The pump is now ready to use. You should not need to prime the pump again.
To treat osteoarthritis knee pain with Pennsaid: Apply the solution only to clean, dry skin. Place 10 drops at a time into your hand and spread the solution over the front, back, and sides of the knee. Apply a total of 40 drops to each affected knee, 4 times per day. You may also drop the medicine directly onto the knee, spreading after every 10 drops.
Avoid showering/bathing for at least 30 minutes after the application.
Wait until the treated area is dry before covering treated skin with clothing or applying sunscreen, insect repellant, lotion, moisturizer, cosmetics, or other topical medication to the same knee you have just treated with Pennsaid.
Store Pennsaid at room temperature away from moisture and heat. Do not freeze.
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?
Avoid drinking alcohol. It may increase your risk of stomach bleeding.
Do not use cosmetics, sunscreen, lotions, insect repellant, or other medicated skin products on the same area you treat with Pennsaid.

Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds) while you are using Pennsaid.

Ask a doctor or pharmacist before using any cold, allergy, or pain medicine. Aspirin and other medicines similar to diclofenac are contained in many combination medicines.
