Brufen 400mg tablets contain ibuprofen, a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce inflammation, and lower fever. Each pack contains 30 tablets with 400mg of ibuprofen per tablet for oral administration. Brufen is commonly used to treat mild to moderate pain such as headaches, dental pain, menstrual cramps, muscular aches, and arthritis. It works by blocking the production of prostaglandins, substances in the body that cause inflammation, pain and fever. The medication should be taken with food to minimize stomach upset. Common side effects may include stomach pain, heartburn, and nausea. Consult a healthcare provider before use if pregnant, breastfeeding, or taking other medications. Not recommended for children under 12 years without medical advice.
