Naproxen is employed to alleviate mild to moderate pain associated with various conditions. It also diminishes pain, swelling, and joint stiffness related to arthritis. Classified as a nonsteroidal anti-inflammatory drug (NSAID), naproxen functions by inhibiting your body’s production of specific natural substances that contribute to inflammation.

Uses and Dosage

Take this medication orally, following the guidance of your doctor, usually twice daily, with or without food. Swallow the tablets whole; do not break, crush, or chew them, as doing so may release the drug too rapidly, increasing the risk of side effects. Ingest the medication with a full glass of water (8 ounces/240 milliliters), unless otherwise instructed by your doctor. Refrain from lying down for at least 10 minutes after taking the drug.

The prescribed dosage is determined based on your medical condition and response to the treatment. To minimize the risk of stomach bleeding and other potential side effects, use the lowest effective dose for the shortest duration possible. Do not exceed the recommended dose or take the medication more frequently than directed. For persistent conditions like arthritis, adhere to your doctor’s instructions for continued use.

In certain cases, such as arthritis, it may take up to two weeks of regular drug administration before experiencing the full benefits.

Inform your doctor if your condition fails to improve or worsens.
