Naproxen Hasco (Naproxen)

Naproxen is an NSAID that alleviates pain and inflammation across several musculoskeletal and gynecologic conditions.

• Mild to moderate pain: Provides analgesic relief for common aches such as headache, dental pain, or minor injuries.
• Osteoarthritis: Reduces joint inflammation and improves mobility in degenerative joint disease.
• Rheumatoid arthritis: Helps control inflammatory activity and pain in autoimmune joint disease.
• Musculoskeletal injuries: Decreases swelling and discomfort after sprains, strains, or soft‑tissue trauma.
• Dysmenorrhea: Relieves menstrual cramps by diminishing uterine prostaglandin production.

• Naproxen exerts its effect by non‑selectively inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which blocks the conversion of arachidonic acid to prostaglandins. The resulting decrease in prostaglandin synthesis diminishes inflammation, pain signaling, and fever generation at the site of tissue injury or disease.

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

Common Side Effects

• Gastrointestinal upset: nausea, dyspepsia, or abdominal discomfort.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Mild skin rash or pruritus.
• Elevated blood pressure in some patients.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding, potentially life‑threatening.
• Cardiovascular events such as myocardial infarction or stroke.
• Severe skin reactions including Stevens‑Johnson syndrome.
• Hepatic enzyme elevation or liver injury.
• Acute renal impairment or failure.
• Anaphylactic or severe hypersensitivity reactions.

Before initiating naproxen therapy, clinicians should evaluate individual risk factors and monitor patients closely.

• Assess gastrointestinal risk: consider ulcer prophylaxis in high‑risk patients.
• Evaluate cardiovascular history: avoid in patients with recent myocardial infarction.
• Monitor renal function: adjust use in chronic kidney disease.
• Use the lowest effective dose for the shortest duration needed.
• Avoid in individuals with known hypersensitivity to NSAIDs.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Naproxen can interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Selective serotonin reuptake inhibitors (SSRIs): heightened bleeding risk.

Moderate Interactions (Monitor Closely)

• Lithium: naproxen may raise lithium serum levels.
• Methotrexate: reduced clearance leading to toxicity.
• ACE inhibitors or diuretics: possible reduction in renal perfusion, monitor kidney function.
