how many mg of ibuprofen can i take in a day

The maximum daily dosage of ibuprofen for adults depends on whether it is prescription or over-the-counter (OTC) use. For OTC use, the maximum is generally 1,200 mg per day, usually taken in divided doses every 4 to 6 hours. For prescription use, especially for conditions like rheumatoid arthritis, the maximum can be up to 2,400 mg per day, divided into three or four doses. Some guidelines allow up to 3,200 mg daily under medical supervision. It is important not to exceed these limits to avoid serious side effects. For children, dosing is based on body weight, with a maximum of about 30–40 mg/kg per day.
