Naproxen Evolan (Naproxen)

Naproxen is an NSAID that reduces inflammation and pain across several clinical settings.

• Pain: provides analgesia for acute and chronic pain conditions.
• Inflammation: diminishes swelling associated with soft‑tissue injuries.
• Fever: lowers elevated body temperature in febrile states.
• Musculoskeletal disorders: improves mobility and reduces discomfort in strains, sprains and back pain.
• Arthritis: alleviates joint pain and stiffness in osteoarthritis and rheumatoid arthritis.

• Naproxen exerts its effect by non‑selectively inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which blocks the conversion of arachidonic acid to prostaglandins. The resulting decrease in prostaglandin synthesis reduces inflammation, pain signaling, and fever generation at the site of tissue injury.

Adverse reactions may range from mild to severe, depending on individual susceptibility and duration of therapy.

Common Side Effects

• Gastrointestinal upset: dyspepsia, abdominal pain.
• Nausea or vomiting.
• Headache.
• Dizziness.
• Mild rash or itching.
• Elevated blood pressure.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Acute renal impairment or failure.
• Cardiovascular events such as myocardial infarction or stroke.
• Severe skin reactions (Stevens‑Johnson syndrome, toxic epidermal necrolysis).
• Hepatic injury or hepatitis.
• Anaphylaxis or severe hypersensitivity reactions.

Before initiating therapy, clinicians should evaluate patient‑specific risk factors and monitor for adverse events.

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

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

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: heightened risk of ulceration.
• Lithium: elevated lithium serum levels.
• Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in renal function.
• Diuretics: may exacerbate renal impairment.
• Selective serotonin reuptake inhibitors (SSRIs): increased bleeding tendency.
• Beta‑blockers: potential for reduced antihypertensive effect.
• Antihypertensive agents: monitor blood pressure control.
