Naproxen Hasco (Naproxen)

• Naproxen acts on inflammatory pathways to relieve pain and swelling in several conditions.
• Pain relief: reduces mild to moderate pain such as headache, dental pain, or menstrual cramps.
• Inflammation reduction: alleviates inflammatory conditions like tendonitis or bursitis.
• Musculoskeletal disorders: helps manage symptoms of osteoarthritis and rheumatoid arthritis.

• Naproxen non‑selectively inhibits cyclooxygenase‑1 and cyclooxygenase‑2 enzymes, decreasing the conversion of arachidonic acid to prostaglandins. Lower prostaglandin levels reduce inflammation, pain signaling, and fever responses at the site of tissue injury.

Naproxen may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Gastrointestinal upset: nausea, dyspepsia, or abdominal discomfort.
• Headache or dizziness.
• Skin irritation at the application site.
• Mild rash or itching.
• Elevated liver enzymes.
• Fluid retention or mild edema.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Cardiovascular events such as myocardial infarction or stroke.
• Severe renal impairment or acute kidney injury.
• Life‑threatening skin reactions (e.g., Stevens‑Johnson syndrome).
• Hepatotoxicity with jaundice.
• Anaphylactic reactions or severe hypersensitivity.

• Before using Naproxen, consider the following safety measures.
• Assess gastrointestinal risk: avoid in patients with a history of ulcers or GI bleeding.
• Evaluate cardiovascular status: use cautiously in those with heart disease or hypertension.
• Check renal function: monitor kidney parameters in patients with renal impairment.
• Avoid in known hypersensitivity: discontinue if allergic reactions occur.
• Monitor concomitant anticoagulant use: increased bleeding risk.
• Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Naproxen can interact with several medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): heightened bleeding risk.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: increased ulcer risk.
• Selective serotonin reuptake inhibitors (SSRIs): amplified bleeding tendency.
• Lithium: elevated lithium serum levels.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in antihypertensive effect.
• Diuretics: risk of reduced renal perfusion.
• Methotrexate: decreased clearance, potential toxicity.
• Digoxin: altered plasma concentrations.
• Antihypertensive agents: monitor blood pressure response.
