Brufen Retard 800mg is a sustained-release formulation containing ibuprofen for extended pain relief. It is used to treat moderate to severe pain, inflammation, and fever. The retard formulation allows for prolonged therapeutic effect with less frequent dosing. This medication contains a high dose (800mg) of ibuprofen in a special sustained-release form. It should be taken as prescribed by your doctor. Common uses include treatment of arthritis, muscle aches, back pain, dental pain, menstrual cramps, and other conditions involving pain and inflammation. As with all NSAIDs, it should be taken with food to minimize stomach upset. Consult your healthcare provider before use, especially if you have a history of stomach ulcers, heart disease, or kidney problems.
