How often to take ibuprofen depends on the prescribed dose and the condition being treated, but it is typically every 4 to 8 hours. It is important to stay within the recommended maximum daily dose to minimize the risk of side effects.
Over-the-counter (OTC) ibuprofen products typically limit adults to 1,200 mg per day unless a clinician tells you otherwise, while prescription dosing may allow higher daily totals, up to 3,200 mg/day, under medical supervision.
Ibuprofen can cause side effects such as stomach discomfort, nausea, vomiting, diarrhea, dizziness, and red spots on the skin. Less common but more serious risks include gastrointestinal (GI) bleeding and kidney failure. Taking doses above what’s recommended can lead to toxicity or poisoning.
If you took ibuprofen at 3:00, your next dose could be anywhere from 7:00 to 11:00, depending on the exact dose and instructions you’re following. To be sure, it is important to contact your primary care provider or the clinician who prescribed the medication. Avoid taking any medication without guidance from a healthcare provider.
