Ibuprofen is a non‑steroidal anti‑inflammatory drug (NSAID) that reduces pain, inflammation, and fever by inhibiting cyclo‑oxygenase (COX) enzymes and lowering prostaglandin production.

Moderate pain and inflammation, such as back pain, arthritis flares, dental pain, muscular injuries, and post‑operative pain when high‑strength NSAIDs are appropriate.

By mouth with food or milk to reduce stomach irritation. Swallow tablets whole with water and take at evenly spaced intervals.

Typical adult dosing is 800 mg two to three times daily (maximum 2,400 mg/day), as directed by your prescriber. Use the lowest effective dose for the shortest time.

Indigestion, heartburn, abdominal pain, nausea, headache, dizziness, fluid retention, and raised blood pressure. Serious: stomach/duodenal ulcers or bleeding, kidney injury, worsening heart failure, and rare severe skin reactions.

Limit or avoid alcohol. Alcohol increases the risk of stomach irritation and bleeding.

Compared to standard 200–400 mg ibuprofen, the 800 mg strength offers stronger anti‑inflammatory effects but a higher risk of side effects. Versus naproxen or diclofenac, effectiveness is similar; choice depends on individual risk factors and prescriber advice.

Stomach bleeding/ulcers, kidney problems (especially with dehydration or in combination with ACE inhibitors/ARBs and diuretics), increased cardiovascular risk with prolonged/high‑dose use, and asthma exacerbation in NSAID‑sensitive patients. Avoid in late pregnancy and use caution after 20 weeks.
