Advil is a brand name for ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and reduce fever. The recommended Advil dosage varies depending on the condition being treated, age, and other factors. According to the official Advil website [3], the recommended dosage for adults and children 12 years and older is 1 or 2 tablets every 4 to 6 hours as needed, not to exceed 6 tablets in 24 hours. The maximum daily dose for children under 12 years old is based on their weight and should be determined by a healthcare professional [3]. It is important to follow the recommended dosage and not exceed the maximum daily dose to avoid potential side effects, such as stomach bleeding, kidney problems, and liver damage [2]. It is also important to talk to a healthcare professional before taking Advil if you have any underlying medical conditions or are taking other medications [2].
