Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, fever, and inflammation [2]. The recommended dosage for Advil depends on the individual's age, weight, and medical condition. It is essential to follow the dosage instructions provided by the healthcare professional or the medication label [2].

According to the NHS, adults can take one or two 200mg tablets of ibuprofen every four to six hours, up to three times in 24 hours [3]. It is recommended to take the medication with or after food to avoid stomach irritation. However, it is crucial to consult a healthcare professional before taking ibuprofen regularly, especially if you have a history of stomach ulcers, asthma, or kidney or liver problems [3].

The Drug Patent Watch website provides information on the patent expiration date of Advil, which is not relevant to the question of how often to take Advil after eating [1].

In conclusion, the frequency of taking Advil after eating depends on the individual's age, weight, and medical condition. It is crucial to follow the recommended dosage instructions provided by a healthcare professional or the medication label. Taking Advil with or after food can help avoid stomach irritation. However, it is essential to consult a healthcare professional before taking ibuprofen regularly, especially if you have a history of stomach ulcers, asthma, or kidney or liver problems [2][3].
