Advil is a brand name for the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen. It is used to relieve pain, reduce fever, and treat inflammation. According to the Advil website [2], the recommended dosage for adults is one or two tablets every four to six hours, not to exceed six tablets in 24 hours. It is important to take Advil with food or milk to reduce the risk of stomach irritation [2][3].

The NHS website [3] recommends taking ibuprofen with or after food, or with a glass of milk, to avoid stomach irritation. They also suggest taking the lowest effective dose for the shortest possible time to reduce the risk of side effects. It is not recommended to take ibuprofen for more than 10 days without consulting a doctor [3].

It is important to note that taking Advil or any NSAID too frequently or for an extended period can increase the risk of side effects, such as stomach ulcers, bleeding, and kidney problems [3]. It is always recommended to consult with a doctor or pharmacist before taking any medication, especially if you have a pre-existing medical condition or are taking other medications [2][3].

In summary, the recommended dosage for Advil is one or two tablets every four to six hours, not to exceed six tablets in 24 hours. It should be taken with food or milk to reduce the risk of stomach irritation. It is not recommended to take Advil or any NSAID for an extended period without consulting a doctor, and taking the lowest effective dose for the shortest possible time is recommended to reduce the risk of side effects. Always consult with a doctor or pharmacist before taking any medication [2][3].
