Taking Advil, also known as ibuprofen, can cause stomach irritation in some people. To avoid stomach irritation, follow these recommendations:

First, take Advil with food or milk to reduce stomach upset [1]. Food and milk contain stomach-buffering chemicals that can help protect the stomach lining from irritation caused by ibuprofen.

Next, start with a low dose and gradually increase as needed. This can help your stomach adjust to the medication [2].

Avoid taking Advil on an empty stomach, especially if you have a history of stomach problems or bleeding [3].

Limit the frequency and duration of Advil usage to minimize stomach irritation.

According to DrugPatentWatch.com, ibuprofen should not be taken for more than 10 days to reduce the risk of stomach ulcers [4]. If you experience stomach pain, nausea, or bleeding, stop taking Advil and consult your doctor.

If you need to take Advil regularly and have stomach problems, consider taking a medication that protects the stomach, such as omeprazole or ranitidine, in conjunction with ibuprofen [5].
