There is no specific timeframe for taking Advil after eating spicy foods as Advil is not a medication that is used to treat the side effects of spicy food. Advil, which contains ibuprofen, is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat pain, fever, and inflammation [1].

Spicy foods can cause a variety of symptoms such as heartburn, indigestion, and stomach pain [2]. If you experience these symptoms after eating spicy foods, it is recommended to wait for a few hours before taking Advil as it can irritate the stomach lining and increase the risk of stomach ulcers [3].

It is important to note that taking Advil can have side effects such as stomach pain, nausea, and indigestion, especially if taken on an empty stomach [3]. Therefore, it is recommended to take Advil with food or milk to reduce the risk of these side effects.

In summary, there is no specific timeframe for taking Advil after eating spicy foods. If you experience symptoms such as heartburn or stomach pain, it is recommended to wait a few hours before taking Advil. It is also important to take Advil with food or milk to reduce the risk of side effects.
