Naproxen Axicur (Naproxen)

Naproxen acts on inflammatory pathways to provide analgesic and antipyretic effects.

• Mild to moderate pain: reduces everyday aches such as headache, dental pain or musculoskeletal discomfort.
• Osteoarthritis and rheumatoid arthritis: diminishes joint inflammation and improves mobility.
• Dysmenorrhea: alleviates menstrual cramps and associated pelvic pain.
• Fever: lowers elevated body temperature in acute febrile states.

• Naproxen reversibly inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing the conversion of arachidonic acid to prostaglandins. The reduced prostaglandin synthesis diminishes peripheral sensitization of nociceptors, lowers inflammatory exudate formation, and curtails fever generation in the hypothalamic thermoregulatory center.

Adverse reactions may vary in frequency and severity.

Common Side Effects

• Gastro‑intestinal upset (indigestion, abdominal discomfort)
• Nausea or vomiting
• Headache
• Dizziness
• Mild skin rash

Serious or Rare Side Effects

• Gastro‑intestinal bleeding or ulceration
• Acute renal impairment or failure
• Severe hypersensitivity reactions (anaphylaxis, Stevens‑Johnson syndrome)
• Hepatotoxicity with elevated liver enzymes
• Cardiovascular events such as myocardial infarction or stroke

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

• Assess gastrointestinal risk: avoid in patients with active ulcers or a history of GI bleeding.
• Evaluate renal function: use caution in those with chronic kidney disease or dehydration.
• Monitor cardiovascular status: patients with heart disease may have increased thrombotic risk.
• Use the lowest effective dose for the shortest duration needed.
• Avoid in individuals with known hypersensitivity to naproxen or other NSAIDs.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Naproxen can alter the pharmacokinetics or pharmacodynamics of several medicines.

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 tendency.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in antihypertensive effect and renal function.
• Diuretics: may exacerbate fluid loss and renal impairment.
• Methotrexate: reduced clearance leading to toxicity.
