PENNSAID® (diclofenac sodium topical solution) 2% w/w
The Easy-to-Apply Topical NSAID for Patients With OA Knee Pain
PENNSAID (diclofenac sodium topical solution) 2% w/w is a nonsteroidal anti-inflammatory drug (NSAID) indicated for the treatment of pain of osteoarthritis (OA) of the knee(s). PENNSAID contains diclofenac sodium, an NSAID, and also includes dimethyl sulfoxide (DMSO), a powerful penetrating agent that helps ensure that diclofenac sodium is absorbed through the skin to the site of inflammation and pain. PENNSAID is an alternative to oral NSAID treatment, reducing systemic exposure to a fraction of that provided by the oral NSAID diclofenac. The only topical NSAID offered with the convenience of a metered-dose pump, PENNSAID is applied in 2 pumps, twice daily, delivering relief right to the site of OA knee pain.
Indications and Usage
PENNSAID (diclofenac sodium topical solution) 2% w/w (PENNSAID 2%) is a nonsteroidal anti-inflammatory drug indicated for the treatment of the pain of osteoarthritis of the knee(s).
Important Safety Information
WARNING: CARDIOVASCULAR AND GASTROINTESTINAL RISK
Cardiovascular Thrombotic Events
- Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use.
- PENNSAID is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.
Gastrointestinal Bleeding, Ulceration, and Perforation
- NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events.
- PENNSAID is contraindicated in patients:
- With a known hypersensitivity to diclofenac or any components of the drug product
- Who have a history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Fatal anaphylactic reactions to NSAIDs have been reported in such patients
- In the setting of coronary artery bypass graft (CABG) surgery
WARNINGS AND PRECAUTIONS
- Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
- There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID, such as PENNSAID, increases the risk of serious GI events.
- Elevation of one or more liver tests may occur during therapy with NSAIDs. Measure transaminases at baseline and periodically in patients receiving long-term therapy with PENNSAID. PENNSAID should be discontinued immediately if abnormal liver tests persist or worsen or if clinical signs and/or symptoms consistent with liver disease develop.
- Hypertension can occur with NSAID treatment. Monitor blood pressure closely with PENNSAID treatment.
- Avoid use of PENNSAID in patients with severe heart failure unless benefits are expected to outweigh the risk.
- Long-term administration of NSAIDs can result in renal papillary necrosis, other renal injury, and renal toxicity. Use PENNSAID with caution in patients at greatest risk of this reaction.
- Anaphylactic reactions may occur in patients with or without known hypersensitivity to PENNSAID and in patients with aspirin-sensitive asthma.
- PENNSAID can cause serious skin adverse reactions such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. Discontinue use at first appearance of skin rash or any other sign of hypersensitivity.
- Anemia has occurred in NSAID-treated patients. Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia.
- Do not:
- Apply PENNSAID to open wounds
- Shower for at least 30 minutes after applying PENNSAID
- Wear clothing over the PENNSAID treated knee(s) until the treated knee(s) is dry
- Wash and dry hands before and after use. Avoid contact of PENNSAID with the eyes and mucous membranes
- Protect treated knee(s) from natural or artificial sunlight
- Wait until the treated knee(s) is completely dry before applying sunscreen, insect repellent, lotion, moisturizer, cosmetics, or other topical medication
- Concurrent use with oral NSAIDs should be avoided unless benefit outweighs risk and periodic laboratory evaluations are conducted.
- See full Prescribing Information for a list of clinically important drug interactions.
- The most common adverse reactions to PENNSAID 1.5% or PENNSAID 2% in clinical trials were: application site reactions such as dryness, exfoliation, erythema, pruritus, pain, induration, rash, scabbing, contact dermatitis characterized by skin erythema and induration, contact dermatitis with vesicles; urinary tract infection; contusion; sinus congestion; nausea; dyspepsia; abdominal pain; flatulence; diarrhea; constipation; edema.
USE IN SPECIFIC POPULATIONS
- PENNSAID should not be used in pregnant or lactating women. Consider withdrawal of NSAIDs, including PENNSAID, in women who have difficulties conceiving or who are undergoing investigation of infertility.
- Safety and efficacy of PENNSAID in pediatric patients has not been established.
