The maximum daily dose of Advil (ibuprofen) varies depending on the individual's age, weight, medical condition, and other factors. The recommended dose for adults is 200-400mg every 4-6 hours, not to exceed 1200mg in a 24-hour period [3]. However, the maximum daily dose for children under 12 years of age should be determined by a doctor based on the child's weight and age [3]. It is important to follow the recommended dosage and not exceed the maximum daily dose to avoid potential adverse effects such as stomach bleeding, kidney damage, and liver damage [2]. Advil is a nonsteroidal anti-inflammatory drug (NSAID) and should not be taken with other NSAIDs, aspirin, or blood thinners [1]. It is also important to consult with a healthcare provider before taking Advil if you have any underlying medical conditions or are taking other medications [2].
