Nalgesin S (Naproxen Sodium)

Naproxen sodium, the active ingredient in Nalgesin S, is a nonsteroidal anti-inflammatory drug (NSAID) presented as an oral tablet for oral use. It provides analgesic, anti‑inflammatory and antipyretic effects for the relief of mild to moderate pain, inflammatory joint conditions such as osteoarthritis and rheumatoid arthritis, and fever in adult patients.

GNH USA supplies Nalgesin S as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, adhering to stringent quality and regulatory standards.

Nalgesin S (naproxen sodium) is used to manage pain and inflammation across several musculoskeletal and systemic conditions.

- Mild to moderate pain: Provides analgesic relief for acute or chronic pain episodes. - Osteoarthritis: Reduces joint pain and improves functional mobility. - Rheumatoid arthritis: Helps control inflammatory joint swelling and stiffness. - Musculoskeletal injuries: Alleviates pain and inflammation from strains, sprains and back pain. - Fever: Lowers elevated body temperature associated with infection or inflammation.

Naproxen sodium may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Gastrointestinal upset: dyspepsia, nausea or abdominal discomfort. - Headache: mild to moderate intensity. - Dizziness or vertigo. - Skin rash or pruritus.

Serious or Rare Side Effects: - Gastrointestinal ulceration or bleeding. - Cardiovascular events such as myocardial infarction or stroke. - Acute renal impairment or worsening of chronic kidney disease. - Severe cutaneous reactions, including Stevens‑Johnson syndrome. - Hepatic injury or elevated liver enzymes. - Anaphylaxis or other severe hypersensitivity reactions.

When prescribing or dispensing Nalgesin S, consider the following precautions to minimize risk.

- Assess gastrointestinal risk: evaluate history of ulcers, bleeding or chronic NSAID use. - Monitor renal function: avoid in patients with severe renal impairment or dehydration. - Evaluate cardiovascular risk: use the lowest effective dose in patients with heart disease. - Use the lowest effective dose for the shortest duration needed. - Avoid in individuals with known hypersensitivity to naproxen or other NSAIDs. - Store at ambient temperature: keep in the original packaging, protect from moisture and heat.

Naproxen sodium can interact with other medicines; awareness of major and moderate interactions helps ensure safe use.

Major Interactions (Avoid): - Warfarin or other anticoagulants: increased risk of bleeding. - Concurrent use of other NSAIDs or aspirin: heightened gastrointestinal toxicity. - Selective serotonin reuptake inhibitors (SSRIs): elevated bleeding risk.

Moderate Interactions (Monitor Closely): - ACE inhibitors or angiotensin receptor blockers: may reduce renal function. - Diuretics: potential for decreased renal perfusion. - Methotrexate: naproxen can raise methotrexate serum levels, increasing toxicity.
