Nalgesin S (Naproxen Sodium)

Naproxen sodium, the active ingredient in Nalgesin S, is a nonsteroidal anti-inflammatory drug (NSAID) presented as an oral dosage form for oral use. It is used to relieve mild to moderate pain, reduce inflammation in conditions such as arthritis, and lower fever in adults. GNH USA supplies Nalgesin S as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Nalgesin S belongs to the NSAID class and is indicated for several painful and inflammatory conditions. - Mild to moderate pain: provides analgesic relief for headaches, dental pain, and musculoskeletal discomfort. - Osteoarthritis: reduces joint inflammation and improves mobility. - Rheumatoid arthritis: alleviates chronic inflammatory symptoms. - Dysmenorrhea: eases menstrual cramps and associated discomfort. - Fever: helps lower elevated body temperature.

Adverse reactions may occur with any NSAID, including naproxen sodium.

Common Side Effects: - Gastrointestinal discomfort: dyspepsia, nausea, or abdominal pain. - Headache or dizziness. - Mild skin rash or itching.

Serious or Rare Side Effects: - Gastrointestinal bleeding or ulcer perforation. - Renal impairment or reduced kidney function. - Cardiovascular events such as myocardial infarction or stroke. - Severe skin reactions (e.g., Stevens‑Johnson syndrome). - Hepatic enzyme elevation or liver injury.

Before initiating therapy, several safety considerations should be reviewed. - Assess renal function: avoid use in patients with severe renal impairment. - Monitor gastrointestinal health: increased risk of ulcer or bleeding, especially with a history of GI disease. - Evaluate cardiovascular risk: use cautiously in patients with established heart disease or thrombotic risk. - Avoid concurrent use with other NSAIDs or anticoagulants: heightened bleeding potential. - Pregnancy and lactation: consult a healthcare professional before use. - Store at ambient temperature: keep in the original container, protect from moisture and heat.

Naproxen sodium can interact with several medicines, requiring attention to avoid adverse outcomes.

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 or ARBs: possible decline in renal function. - Corticosteroids: additive risk of gastrointestinal ulceration.
