Advil is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat pain, fever, and inflammation. However, like other NSAIDs, Advil can cause stomach ulcers, which can be a serious and potentially life-threatening condition. The symptoms of Advil-induced ulcers can include abdominal pain, nausea, vomiting, bloating, indigestion, loss of appetite, and black, tarry stools [2].

According to a study cited by the National Center for Biotechnology Information (NCBI), the risk of developing an ulcer is higher in people who take NSAIDs like Advil for an extended period of time [2]. Additionally, people who are older, have a history of ulcers, or who smoke or drink alcohol are also at an increased risk of developing ulcers [2].

If you are experiencing symptoms of an ulcer, it is important to seek medical attention immediately. In severe cases, an ulcer can cause internal bleeding, which can be life-threatening. Treatment for an Advil-induced ulcer may include medication to reduce stomach acid and antibiotics to treat any infections [3].

In conclusion, Advil-induced ulcers can cause a range of symptoms, including abdominal pain, nausea, vomiting, bloating, indigestion, loss of appetite, and black, tarry stools. If you are experiencing any of these symptoms, it is important to seek medical attention immediately. Additionally, it is important to use Advil and other NSAIDs only as directed and to talk to your doctor if you have any concerns about their use [2][3].
