Naproxen Stada (Naproxen)

• Naproxen acts on inflammatory pathways to relieve pain and swelling in several musculoskeletal and gynecologic conditions.
• Pain: Provides symptomatic relief of mild to moderate acute or chronic pain.
• Inflammation: Reduces swelling and redness associated with inflammatory processes.
• Rheumatoid arthritis: Helps control joint pain and stiffness in rheumatoid arthritis.
• Osteoarthritis: Alleviates discomfort and improves function in osteoarthritis.
• Dysmenorrhea: Relieves menstrual cramps and associated pelvic pain.

• Naproxen exerts its therapeutic effect by reversibly 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.

Common Side Effects

• Gastrointestinal upset, including dyspepsia or heartburn.
• Nausea or vomiting.
• Headache.
• Dizziness.
• Mild skin rash or itching.
• Elevated blood pressure in some patients.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding, which can be life‑threatening.
• Cardiovascular events such as myocardial infarction or stroke.
• Acute renal failure or worsening of chronic kidney disease.
• Severe skin reactions, including Stevens‑Johnson syndrome.
• Hepatic dysfunction with elevated liver enzymes.
• Anaphylaxis or other severe allergic reactions.

• Before initiating therapy, consider the following safety measures.
• Assess renal function: Adjust or avoid use in patients with significant renal impairment.
• Monitor gastrointestinal risk: Use cautiously in individuals with a history of ulcer or bleeding.
• Avoid concomitant anticoagulants: Increased risk of hemorrhage when combined with warfarin or similar agents.
• Use caution in cardiovascular disease: May elevate risk of thrombotic events.
• Pregnancy and lactation: Consult a prescriber; limited safety data are available.
• Store at ambient temperature: Keep in the original container, protect from moisture and heat.

Naproxen may interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): Heightened bleeding risk.
• Other NSAIDs or aspirin: Additive gastrointestinal toxicity.
• Selective serotonin reuptake inhibitors (SSRIs): Increased bleeding potential.
• ACE inhibitors or ARBs: May reduce renal perfusion.
• Lithium: Elevated lithium levels and toxicity.

Moderate Interactions (Monitor Closely)

• Diuretics: Potential for reduced renal clearance.
• Corticosteroids: Enhanced risk of ulceration.
• Methotrexate: Decreased clearance, raising toxicity.
• Antihypertensives: Possible attenuation of blood‑pressure control.
• Oral hypoglycemics: May affect glucose regulation.
