Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, inflammation, and fever. According to the Advil website [2], taking Advil with food or milk can help reduce stomach upset. The Healthline website [3] also recommends taking ibuprofen with food or milk to reduce the risk of stomach irritation. However, it is important to note that taking Advil with food may delay the onset of its effects. The Drug Patent Watch website [1] does not provide information on whether Advil should be taken with food or not. It is always best to consult with a healthcare provider before taking any medication, especially if you have a history of stomach ulcers, bleeding, or other gastrointestinal problems.
