Naprosyn (Naproxen)

• Naprosyn is an NSAID that reduces inflammation and pain in several musculoskeletal and gynecologic conditions.
• Arthritis: alleviates joint pain and swelling associated with osteoarthritis and rheumatoid arthritis.
• Dysmenorrhea: relieves menstrual cramps and associated discomfort.
• Acute pain: provides short‑term relief of mild to moderate pain such as dental or musculoskeletal pain.
• Inflammatory conditions: reduces inflammation in soft‑tissue injuries and bursitis.

• Naproxen exerts its effect by non‑selectively inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which decreases the synthesis of prostaglandins responsible for pain, inflammation and fever. This reduction in prostaglandin levels leads to the observed analgesic, anti‑inflammatory and antipyretic actions.

Adverse reactions may vary in frequency and severity.

Common Side Effects

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

Serious or Rare Side Effects

• Gastrointestinal bleeding, ulceration or perforation.
• Cardiovascular events including myocardial infarction or stroke.
• Renal impairment or acute kidney injury.
• Severe skin reactions such as Stevens‑Johnson syndrome.
• Hepatic dysfunction or elevated liver enzymes.
• Anaphylaxis or severe hypersensitivity reactions.

• When prescribing Naprosyn, clinicians should consider several safety measures.
• Assess gastrointestinal risk: evaluate history of ulcers or bleeding before use.
• Monitor renal function: check creatinine and electrolytes in patients with kidney disease.
• Evaluate cardiovascular status: use cautiously in patients with heart disease or hypertension.
• Use lowest effective dose: limit duration to the shortest period needed for symptom control.
• Avoid in known hypersensitivity: discontinue if allergic reactions occur.
• Store at ambient temperature: keep in original packaging, protect from moisture and heat.

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: heightened gastrointestinal toxicity.
• Selective serotonin reuptake inhibitors (SSRIs): elevated bleeding risk.
• ACE inhibitors or ARBs: may reduce renal perfusion and function.
• Lithium: naproxen can raise lithium serum levels.

Moderate Interactions (Monitor Closely):\n- Diuretics: potential for reduced diuretic efficacy and renal effects.

• Antihypertensives: possible attenuation of blood pressure control.
• Methotrexate: naproxen may increase methotrexate toxicity.
• Corticosteroids: additive risk of gastrointestinal ulceration.
• Cyclosporine: enhanced nephrotoxic potential.
