Naproxen Viatris

Naproxen, the active ingredient in Naproxen Viatris, is a nonsteroidal anti-inflammatory drug presented as an oral tablet for oral use. It treats pain, inflammation, fever and arthritis in adults and adolescents when prescribed. 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 pain and inflammation across several musculoskeletal and inflammatory conditions.

- Pain: provides relief of mild to moderate acute pain such as dental or postoperative discomfort. - Inflammation: diminishes swelling associated with soft‑tissue injuries. - Fever: lowers elevated body temperature in febrile states. - Arthritis: alleviates joint pain and stiffness in osteoarthritis and rheumatoid arthritis. - Musculoskeletal disorders: improves function in back pain, tendonitis and bursitis.

Naproxen may cause a range of adverse reactions, from mild discomfort to serious health concerns.

Common Side Effects: - Gastrointestinal upset: nausea, dyspepsia or heartburn. - Headache: mild to moderate intensity. - Dizziness: occasional light‑headedness. - Skin rash: mild erythema or itching. - Fluid retention: mild swelling of ankles or feet.

Serious or Rare Side Effects: - Gastrointestinal bleeding or ulceration. - Cardiovascular events: myocardial infarction or stroke. - Severe renal impairment or acute kidney injury. - Hepatotoxicity: elevated liver enzymes or hepatitis. - Anaphylaxis: life‑threatening allergic reaction.

When using naproxen, consider the following precautions to minimize risk.

- Assess renal function: monitor kidney parameters in patients with existing impairment. - Evaluate cardiovascular risk: use cautiously in individuals with heart disease or stroke history. - Avoid in active gastrointestinal ulceration: increased risk of bleeding. - Limit use in elderly: higher susceptibility to adverse effects. - Store at ambient temperature: keep in the original pack, protect from moisture.

Naproxen can interact with several medicines; awareness of key interactions helps prevent complications.

Major Interactions (Avoid): - Anticoagulants (e.g., warfarin): increased bleeding risk. - Selective serotonin reuptake inhibitors (SSRIs): heightened bleeding tendency. - Lithium: elevated lithium serum concentrations. - Methotrexate: reduced clearance leading to toxicity. - Strong CYP450 inhibitors (e.g., ketoconazole): increased naproxen exposure.

Moderate Interactions (Monitor Closely): - ACE inhibitors: possible decline in renal function. - Diuretics: additive effect on renal impairment. - Other NSAIDs: cumulative gastrointestinal and renal toxicity. - Corticosteroids: higher risk of gastrointestinal ulceration. - Antihypertensive agents: may blunt blood‑pressure‑lowering effect.
