Advil is a brand name for the drug ibuprofen [1]. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain, reduce fever, and reduce inflammation. According to the NHS, ibuprofen can be taken with or without food, but it should be taken with a glass of water or milk to reduce the risk of stomach irritation [2]. However, the NHS does not provide any specific information on how long after consuming milk one can take Advil.

Advil's official website states that Advil can be taken with food or milk to help prevent stomach upset [3]. However, it does not provide any specific information on how long after consuming milk one can take Advil.

Based on the sources provided, it is safe to assume that ibuprofen can be taken with milk, but it is not clear how long after consuming milk one can take Advil. Therefore, it is recommended to consult a healthcare professional for specific advice on how to take Advil and any other medications.
