The recommended dosage of Advil, which contains ibuprofen, depends on the individual's age and medical condition. According to Mayo Clinic [3], adults and children over 12 years old can take one or two tablets of Advil every 4 to 6 hours as needed, not exceeding six tablets in 24 hours. The maximum daily dose for adults is 3200 mg, while the maximum daily dose for children is 40 mg/kg. However, the dosage may vary depending on the individual's medical condition and other factors, so it is essential to consult a doctor before taking Advil. The Advil website [2] also recommends that individuals read and follow the label carefully and avoid taking more than the recommended dose. The Drug Patent Watch website [1] provides information on the different strengths of Advil available in the market, ranging from 200mg to 400mg. It is crucial to note that taking too much Advil can lead to adverse effects such as stomach bleeding, kidney damage, and even heart attack or stroke, especially if taken for an extended period or in high doses. Therefore, it is vital to follow the recommended dosage and consult a doctor if you have any concerns.
