Naproxen Genoptim (Naproxen)

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

• Pain: provides analgesia by lowering pain perception.
• Inflammation: diminishes swelling and tissue irritation.
• Fever: helps lower elevated body temperature.
• Musculoskeletal disorders: eases discomfort in strains, sprains and back pain.
• Arthritis: reduces joint pain and stiffness associated with osteoarthritis and rheumatoid arthritis.

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

Adverse reactions may range from mild to severe and should be monitored during therapy.

Common Side Effects

• Gastrointestinal upset: dyspepsia, nausea, or abdominal discomfort.
• Headache: mild to moderate intensity.
• Dizziness: occasional light‑headedness.
• Rash: transient skin redness or itching.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Renal impairment or acute kidney injury.
• Cardiovascular events such as myocardial infarction or stroke.
• Severe skin reactions including Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Anaphylaxis: rare but potentially life‑threatening allergic reaction.
• Hepatic dysfunction: elevated liver enzymes or hepatitis.

Before initiating therapy, consider the following safety measures.

• Renal function assessment: evaluate baseline kidney status, especially in elderly patients.
• Cardiovascular risk evaluation: avoid in patients with recent myocardial infarction or uncontrolled hypertension.
• Gastrointestinal history: use cautiously in individuals with prior ulcers or bleeding.
• Concomitant anticoagulant use: monitor for enhanced bleeding risk.
• Hypersensitivity check: discontinue if signs of allergic reaction appear.
• Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Naproxen can affect the activity of several co‑administered medicines.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Lithium: naproxen may raise lithium serum concentrations.
• Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors: may diminish antihypertensive effect and affect renal function.
• SSRIs: combined use can raise gastrointestinal bleeding risk.
• Diuretics: potential for reduced renal perfusion and electrolyte imbalance.
