Naproxen (Naproxen Bp)

Naproxen works by reversibly blocking the cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes that convert arachidonic acid into prostaglandins. Prostaglandins are key mediators of inflammation, pain signaling, and fever. By lowering prostaglandin levels, naproxen diminishes the inflammatory response, reduces peripheral sensitization of nerve endings, and helps lower body temperature when fever is present.

The appropriate naproxen dose is individualized by the prescribing healthcare professional based on the specific indication, severity of symptoms, patient age, renal and hepatic function, and any concurrent medications. Dosage may differ for short‑term pain versus chronic conditions such as arthritis, and the prescriber will balance efficacy with the lowest effective dose to limit adverse effects.

Naproxen is classified as Pregnancy Category B, indicating that animal studies have not shown a risk but there are no well‑controlled studies in pregnant women. It is generally avoided in the third trimester because of potential fetal cardiovascular complications. Limited data suggest that short‑term use during early pregnancy or lactation is unlikely to cause harm, but a clinician should always evaluate the risk‑benefit ratio.

To request naproxen, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, confirming trade or institutional credentials before providing a formal quotation. The sales team then replies with pricing, availability, shipping details (including any cold‑chain requirements) and the necessary import documentation.

Naproxen and ibuprofen belong to the same NSAID class but differ in pharmacokinetics. Naproxen has a longer half‑life, allowing twice‑daily dosing, whereas ibuprofen often requires three‑four times daily. Both inhibit COX enzymes, yet naproxen may have a slightly lower cardiovascular risk profile in some studies. Choice between them depends on patient tolerance, dosing convenience, and specific safety considerations such as gastrointestinal or renal risk.

Naproxen should be stored at ambient temperature, preferably below 25 °C (77 °F). Keep the product in its original packaging to protect it from moisture and light. Do not store in areas with high humidity or direct sunlight, and keep it out of reach of children.

Naproxen is taken orally, usually with a full glass of water. It can be taken with or without food, although taking it with meals may reduce gastrointestinal discomfort. The tablet or capsule should be swallowed whole; it should not be crushed, chewed, or dissolved unless the formulation specifically allows it.

The most serious adverse events associated with naproxen include gastrointestinal bleeding or ulceration, severe cardiovascular events such as heart attack or stroke, acute kidney injury, and rare but life‑threatening skin reactions like Stevens‑Johnson syndrome. Patients should seek immediate medical attention if they notice black stools, sudden severe headache, chest pain, swelling of the legs, or widespread rash.

Naproxen is contraindicated in individuals with a known hypersensitivity to naproxen or other NSAIDs, those with active gastrointestinal bleeding or ulcer disease, and patients in the third trimester of pregnancy. It should also be avoided by patients with severe heart failure, uncontrolled hypertension, or significant renal impairment unless a specialist advises otherwise.
