Naproxen Msr Teva (Naproxen)

Naproxen is an NSAID that reduces pain and inflammation across several common conditions.

• Pain: provides relief from mild to moderate acute pain.
• Inflammation: decreases swelling associated with musculoskeletal disorders.
• Fever: helps lower elevated body temperature.
• Arthritis: alleviates joint pain and stiffness in osteoarthritis and rheumatoid arthritis.

• Naproxen inhibits cyclooxygenase (COX‑1 and COX‑2) enzymes, which blocks the conversion of arachidonic acid to prostaglandins. Reduced prostaglandin synthesis diminishes inflammation, pain signaling, and fever generation at the site of tissue injury.

Adverse reactions may vary in frequency and severity.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or abdominal pain.
• Headache: mild to moderate intensity.
• Dizziness: occasional light‑headedness.
• Skin rash: mild erythema or pruritus.
• Elevated blood pressure: modest increase in some patients.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding: may present with melena or hematemesis.
• Renal impairment: reduced kidney function or acute renal failure.
• Hepatotoxicity: elevated liver enzymes or hepatitis.
• Cardiovascular events: increased risk of myocardial infarction or stroke.
• Severe hypersensitivity: anaphylaxis, angioedema, or Stevens‑Johnson syndrome.

Before initiating therapy, consider patient‑specific risk factors and monitor appropriately.

• Renal function: assess baseline creatinine in patients with kidney disease.
• Gastrointestinal risk: avoid in individuals with active ulcers or a history of GI bleeding.
• Cardiovascular health: use cautiously in patients with coronary artery disease or hypertension.
• Concomitant NSAIDs: do not combine with other non‑selective NSAIDs or aspirin without medical supervision.
• Pregnancy and lactation: avoid unless clearly indicated by a healthcare professional.
• Store at ambient temperature: keep below 25°C, retain in original packaging, and protect from moisture.

Naproxen may alter the effect of several co‑administered medicines.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• Selective serotonin reuptake inhibitors (SSRIs): heightened gastrointestinal hemorrhage.
• ACE inhibitors or ARBs: potential reduction in renal function.

Moderate Interactions (Monitor Closely)

• Diuretics: possible decrease in antihypertensive efficacy.
• Lithium: risk of lithium toxicity due to reduced renal clearance.
• Methotrexate: may raise serum methotrexate levels, enhancing toxicity.
