Advil, also known as ibuprofen, is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain and reduce inflammation [1]. While it is not specifically designed to prevent heartburn, it may help alleviate symptoms associated with heartburn caused by spicy foods. However, it is important to note that ibuprofen may cause side effects, including gastrointestinal problems such as heartburn, stomach pain, and nausea [2]. Therefore, it is recommended to take Advil with food to reduce the risk of developing these side effects [3]. Additionally, if you frequently experience heartburn after eating spicy foods, it may be helpful to make dietary changes or speak with a healthcare provider to determine the underlying cause and develop an appropriate treatment plan.
