• Like other NSAIDs, diclofenac acts as by inhibiting cellular cyclooxygenases (Cox-1 and Cox-2), which results in a decrease in production of pro-inflammatory prostaglandin, prostacyclin and thromboxane products, important mediators of inflammation and pain.
• Diclofenac has analgesic as well as antipyretic and anti inflammatory activities.

Who Should Not Use this medicine ?

This medicine cannot be used in patients with:

• History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.
• In the setting of coronary artery bypass graft (CABG) surgery.

What drug interactions can this medicine cause?

• Monitor patients for bleeding who are concomitantly using PENNSAID with drugs that interfere with hemostasis. Concomitant use of PENNSAID and analgesic doses of aspirin is not generally recommended.
• Concomitant use with PENNSAID may diminish the antihypertensive effect of these drugs. Monitor blood pressure.
• Concomitant use with PENNSAID in elderly, volume depleted, or those with renal impairment may result in deterioration of renal function. In such high risk patients, monitor for signs of worsening renal function.
• NSAIDs can reduce natriuretic effect of furosemide and thiazide diuretics. Monitor patients to assure diuretic efficacy including antihypertensive effects.
• Concomitant use with PENNSAID can increase serum concentration and prolong half-life of digoxin. Monitor serum digoxin levels.

Is this medicine FDA approved?

What special precautions should I follow?

• Inform patients of warning signs and symptoms of hepatotoxicity. Discontinue if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop.
• Patients taking some antihypertensive medications may have impaired response to these therapies when taking NSAIDs. Monitor blood pressure.
• Avoid use of PENNSAID in patients with severe heart failure unless benefits are expected to outweigh risk of worsening heart failure.
• Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia. Avoid use of PENNSAID in patients with advanced renal disease unless benefits are expected to outweigh risk of worsening renal function.
• Anaphylactic Reactions may occur with PENNSAID. Seek emergency help if an anaphylactic reaction occurs.
• PENNSAID is contraindicated in patients with aspirin-sensitive asthma. Monitor patients with preexisting asthma (without aspirin sensitivity).
• NSAIDs, including diclofenac, can cause serious skin adverse reactions such as exfoliative dermatitis, Stevens-Johnson Syndrome(SJS), and toxic epidermal necrolysis (TEN), which can be fatal. Discontinue PENNSAID at first appearance of skin rash or other signs of hypersensitivity.
• Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported in patients taking NSAIDs such as PENNSAID. Discontinue and evaluate clinically.
• Limit use of NSAIDs, including PENNSAID, between about 20 to 30 weeks in pregnancy due to the risk of oligohydramnios/fetal renal dysfunction. Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy due to the risks of oligohydramnios/fetal renal dysfunction and premature closure of the fetal ductus arteriosus.
• Anemia has occurred in NSAID-treated patients. Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia.
• Avoid exposure of treated knee(s) to natural or artificial sunlight.
• Avoid contact of PENNSAID with eyes and mucosa.

• Consider activated charcoal in symptomatic patients seen within four hours of ingestion or in patients with a large overdosage (5 to 10 times the recommended dosage).
• Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding.
