Naproxen Generics Uk (Naproxen)

Naproxen is an NSAID that reduces inflammation and pain in several musculoskeletal and gynecological conditions.

• Mild to moderate pain: provides analgesic relief for acute or chronic pain such as headache, dental pain or postoperative discomfort.
• Osteoarthritis: decreases joint inflammation and improves mobility in degenerative joint disease.
• Rheumatoid arthritis: helps control inflammatory activity and joint swelling in autoimmune arthritis.
• Dysmenorrhea: alleviates menstrual cramps by reducing uterine prostaglandin production.

• Naproxen reversibly inhibits both cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, leading to decreased conversion of arachidonic acid to prostaglandins. The reduction in prostaglandin synthesis diminishes inflammation, pain signaling, and fever generation throughout the body.

Naproxen may cause a range of adverse reactions, from mild to serious, depending on individual susceptibility and duration of therapy.

Common Side Effects

• Gastrointestinal upset: nausea, dyspepsia, or abdominal discomfort.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Rash or mild skin irritation.
• Elevated blood pressure.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulceration.
• Cardiovascular events such as myocardial infarction or stroke.
• Acute renal impairment or failure.
• Severe skin reactions (e.g., Stevens‑Johnson syndrome).
• Hepatic enzyme elevation or liver injury.
• Anaphylaxis or severe hypersensitivity reactions.

Before initiating naproxen therapy, clinicians should evaluate patient‑specific risk factors and monitor for potential complications.

• Assess gastrointestinal risk: consider ulcer prophylaxis in patients with prior GI bleeding.
• Monitor renal function: especially in elderly or those with pre‑existing kidney disease.
• Evaluate cardiovascular risk: use lowest effective dose for shortest duration.
• Avoid in known hypersensitivity to NSAIDs or aspirin.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Naproxen can interact with several drug classes, altering efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• Other NSAIDs or COX‑2 inhibitors: additive gastrointestinal toxicity.
• Selective serotonin reuptake inhibitors (SSRIs): heightened risk of GI bleeding.

Moderate Interactions (Monitor Closely)

• Diuretics: may reduce renal perfusion.
• ACE inhibitors or ARBs: potential for reduced antihypertensive effect and renal impairment.
• Alcohol: enhances gastric irritation and bleeding potential.
