What is Pennsaid?
Pennsaid topical solution contains diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing hormones that cause inflammation and pain in the body.
Pennsaid 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 other purposes not listed in this medication guide.
Important information about Pennsaid
Do not use Pennsaid if you have ever had asthma or a severe allergic reaction caused by aspirin, diclofenac (Cataflam, Voltaren), or another non-steroidal anti-inflammatory drug (NSAID). Do not use Pennsaid just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).
Before using Pennsaid, tell your doctor if you have heart disease, congestive heart failure, high blood pressure, a history of heart attack or stroke, a history of stomach ulcer or bleeding, liver or kidney disease, a blood clotting disorder, asthma, or nasal polyps.
While the risk of absorbing diclofenac into your bloodstream is low, an NSAID may cause life-threatening heart or circulation problems such as heart attack or stroke, especially if you use it long term.
Get emergency medical help if you have chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.
Pennsaid may also cause serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and can occur without warning while you are using Pennsaid, especially in older adults.
Call your doctor at once if you have symptoms of stomach bleeding such as black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.

Pennsaid may be harmful to an unborn baby. If you are pregnant, ask your doctor if it is safe for you to use Pennsaid. Tell your doctor if you become pregnant during treatment. Diclofenac can pass into breast milk and may harm a nursing baby. You should not breast-feed while using Pennsaid.
How should I use Pennsaid?
Use Pennsaid exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. When treating osteoarthritis, keep using any oral medications your doctor has prescribed.
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. Wash your hands after applying Pennsaid.
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.
Wait until the Pennsaid 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.
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 getting Pennsaid in your mouth, nose, or eyes. If this does happen, rinse with water. Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds) while you are using Pennsaid.
Avoid taking aspirin, oral (pill form) diclofenac (Cataflam, Voltaren), or other NSAIDs without your doctor's advice. This includes ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), indomethacin, piroxicam (Feldene), nabumetone (Relafen), etodolac (Lodine), and others.
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. Taking certain products together can cause you to get too much of a certain drug. Check the label to see if a medicine contains aspirin, ibuprofen, ketoprofen, or naproxen.

Although the risk of serious side effects is low when diclofenac is applied to the skin, you should be aware of side effects that can occur if the medication is absorbed into your bloodstream.
