Naproxen Orifarm (Naproxen)

• Naproxen is an NSAID that reduces inflammation and pain across several musculoskeletal and gynecologic conditions.
• Mild to moderate pain: provides analgesic relief for acute or chronic pain states.
• Inflammation: diminishes swelling associated with inflammatory disorders.
• Fever: lowers elevated body temperature.
• Osteoarthritis: improves joint function and reduces discomfort.
• Rheumatoid arthritis: helps control disease‑related pain and stiffness.
• Dysmenorrhea: eases menstrual‑related cramping and pain.

• Naproxen reversibly inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing the conversion of arachidonic acid to prostaglandins. Reduced prostaglandin synthesis leads to lower inflammation, pain signalling, and fever generation at sites of tissue injury.

Adverse reactions may range from mild to severe and should be monitored during therapy.

Common Side Effects

• Gastrointestinal discomfort, such as dyspepsia or nausea.
• Headache or dizziness.
• Mild skin rash or itching.
• Elevated blood pressure.
• Fluid retention or peripheral edema.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Cardiovascular events such as myocardial infarction or stroke.
• Acute renal failure or worsening of chronic kidney disease.
• Severe skin reactions (e.g., Stevens‑Johnson syndrome).
• Hepatic injury or elevated liver enzymes.
• Anaphylactic or severe hypersensitivity reactions.

• Before initiating therapy, clinicians should evaluate patient‑specific risk factors and monitor for adverse outcomes.
• Assess gastrointestinal risk: review history of ulcers, bleeding, or chronic NSAID use.
• Monitor renal function: check baseline creatinine and adjust in patients with impairment.
• Avoid in known hypersensitivity: discontinue if allergic reactions occur.
• Use lowest effective dose: limit duration to the shortest period needed for symptom control.
• Avoid concomitant anticoagulants when possible: increase bleeding risk.
• Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Naproxen may interact with several drug classes, requiring careful assessment.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): heightened bleeding risk.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: increased ulceration potential.
• Lithium: elevated serum lithium levels.
• Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely)

• Diuretics: possible reduction in renal perfusion.
• Antihypertensives (ACE inhibitors, ARBs): may blunt blood‑pressure control.
• Beta‑blockers: potential for reduced antihypertensive effect.
• Digoxin: altered renal excretion.
• Alcohol: increased gastrointestinal irritation and bleeding risk.
