Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce fever, and decrease inflammation. According to the National Health Service (NHS) [3], it is recommended to take ibuprofen with or after food to reduce the risk of stomach irritation. Healthline [2] also advises taking ibuprofen with food or milk if you experience stomach upset. The Drug Patent Watch [1] does not provide specific information on the timing of taking Advil after eating. However, it is generally recommended to wait at least 30 minutes to an hour after eating before taking ibuprofen to ensure proper absorption into the bloodstream [2]. It is important to follow the instructions on the label or as directed by a healthcare provider and not exceed the recommended dose. Additionally, if you have any underlying medical conditions or are taking other medications, it is important to consult with a healthcare provider before taking Advil or any other medication.
