Naproxen Viatris

Naproxen, the active ingredient in Naproxen Viatris, is a nonsteroidal anti-inflammatory drug (NSAID) presented as an oral dosage form for oral use. It treats pain, inflammation and fever in adult patients. GNH USA supplies Naproxen Viatris as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Naproxen is an NSAID that reduces inflammation and pain by inhibiting cyclooxygenase enzymes. - Osteoarthritis: reduces joint pain and stiffness. - Rheumatoid arthritis: alleviates inflammatory joint symptoms. - Acute musculoskeletal pain: provides analgesia and reduces swelling. - Dysmenorrhea: relieves menstrual cramps. - Fever: lowers elevated body temperature.

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

Common Side Effects: - Gastrointestinal upset: dyspepsia, nausea, or abdominal discomfort. - Headache: mild to moderate intensity. - Dizziness: occasional light‑headedness. - Rash: mild skin irritation.

Serious or Rare Side Effects: - Gastrointestinal bleeding or ulcer perforation. - Renal impairment: reduced kidney function. - Hepatic dysfunction: elevated liver enzymes. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Cardiovascular events: increased risk of thrombotic complications.

Before prescribing Naproxen, clinicians should evaluate patient‑specific risk factors. - Assess renal function: avoid in severe renal impairment. - Monitor gastrointestinal risk: use cautiously in patients with a history of ulcers or bleeding. - Avoid concomitant anticoagulants: heightened bleeding risk. - Use the lowest effective dose: minimizes adverse events. - Pregnancy and lactation: consult a healthcare professional before use. - Store at room temperature: keep in the original container, protect from moisture and heat.

Naproxen can interact with several medicines, requiring careful management.

Major Interactions (Avoid): - Anticoagulants (e.g., warfarin): increased risk of serious bleeding. - Selective COX‑2 inhibitors: additive cardiovascular risk. - Lithium: naproxen may raise lithium serum concentrations. - Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely): - ACE inhibitors: possible decline in renal function. - Diuretics: may diminish renal perfusion. - SSRIs: heightened bleeding tendency.
