Advil is a popular brand of nonsteroidal anti-inflammatory drugs (NSAIDs) that are used to treat various types of pain and inflammation. However, like all medications, Advil can cause side effects, particularly stomach issues. Here are some ways to prevent Advil stomach issues based on the provided sources.

1. Take Advil with food: Taking Advil with food can help reduce stomach irritation. According to the Hospital for Special Surgery [2], taking NSAIDs with food or milk can help reduce the risk of stomach upset.

2. Use the lowest effective dose: The higher the dose of Advil, the greater the risk of stomach issues. The Drug Patent Watch [1] notes that the recommended maximum daily dose of Advil is 3200mg, but most people can achieve pain relief with a lower dose. It is recommended to use the lowest effective dose for the shortest duration possible.

3. Avoid alcohol: Drinking alcohol while taking Advil can increase the risk of stomach irritation and bleeding. The National Center for Biotechnology Information [3] notes that alcohol can increase the permeability of the stomach lining, making it more susceptible to damage from NSAIDs.

4. Consider alternative pain relief options: If you are prone to stomach issues or have a history of stomach ulcers, you may want to consider alternative pain relief options. The Hospital for Special Surgery [2] suggests that acetaminophen (Tylenol) may be a better option for people who are at risk of stomach issues.

In summary, taking Advil with food, using the lowest effective dose, avoiding alcohol, and considering alternative pain relief options can help prevent Advil stomach issues. However, it is important to speak with a healthcare provider before making any changes to your medication regimen.
