INDICATIONS AND USAGE
PENNSAID® diclofenac sodium topical solution) 2% w/w is a nonsteroidal anti-inflammatory drug (NSAID) used for treating the pain of osteoarthritis of the knee(s).
IMPORTANT RISK INFORMATION
WARNING: HEART, STOMACH AND INTESTINE RISK
- Nonsteroidal anti-inflammatory drugs (NSAIDs) may cause an increased risk of serious heart clotting events, heart attack, and stroke, which can kill you. This risk may increase with longer use. Patients with heart disease or risk factors for heart disease may be at greater risk.
- PENNSAID should not be used if you are in the hospital for certain heart surgeries.
Stomach and Intestine Risk
- NSAIDs cause an increased risk of serious stomach and intestine events including bleeding, ulcers, and holes in the stomach or intestines, which can kill you. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious stomach and intestine events.
- DO NOT USE PENNSAID if you:
- are in the hospital for certain heart surgeries.
- know you are allergic to diclofenac sodium or any other ingredient of PENNSAID.
- have experienced asthma, hives, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, allergic reactions, that will rarely kill you, to NSAIDs have been reported in such patients.
WARNINGS AND PRECAUTIONS
- Elevation of one or more liver tests may occur during therapy with NSAIDs. PENNSAID should be discontinued immediately if abnormal liver tests persist or worsen.
- Use with caution in patients with fluid retention or heart failure. Hypertension can occur with NSAID treatment. Monitor blood pressure closely with PENNSAID treatment.
- Long-term use of NSAIDs can result in severe kidney injury. Use PENNSAID with caution in patients at greatest risk of this reaction, including the elderly, those with impaired kidney function, heart failure, liver dysfunction, and those taking diuretics and ACE-inhibitors (certain blood pressure medicines).
- Severe allergic reactions may occur without prior use of PENNSAID. NSAIDs can cause serious skin reactions such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can kill you.
- Wash and dry hands before and after use. Avoid contact of PENNSAID with the eyes, nose and mouth.
- PENNSAID was not studied under the conditions of heat application, complete covering bandages, or exercise; therefore, concurrent use of PENNSAID under these conditions is not recommended.
- Do not:
- apply PENNSAID to open wounds.
- shower for at least 30 minutes after applying PENNSAID.
- wear clothing over the PENNSAID treated knee until the treated knee is dry.
- Protect treated knee(s) from sunlight (real and tanning booths). Topicals, such as sunscreen and bug repellent, may be applied after PENNSAID treated knee(s) are completely dry.
- Do not use with oral NSAIDs unless your doctor says it is OK and you have lab tests to check your progress.
