Advil is a popular over-the-counter medication used to relieve pain and reduce fever. The active ingredient in Advil is ibuprofen, which belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). According to the Advil website [3], it is safe to take Advil after eating, as long as you follow the recommended dosage and usage instructions.

However, Healthline [2] warns that taking ibuprofen on an empty stomach can increase the risk of stomach irritation and ulcers. It is recommended to take Advil with food or milk to help reduce the risk of these side effects.

It is also important to note that Advil should not be taken by certain individuals, such as those with a history of stomach bleeding or ulcers, kidney or liver disease, or asthma. Additionally, Advil should not be taken with certain medications, such as blood thinners, as it can increase the risk of bleeding.

In conclusion, Advil is safe to take after eating as long as the recommended dosage and usage instructions are followed. However, taking it on an empty stomach can increase the risk of stomach irritation and ulcers. It is important to consult with a healthcare provider before taking Advil if you have any underlying medical conditions or are taking other medications.
