Ibuprofen is the active ingredient in Advil, and it is also available as a generic drug [3]. Like any medication, ibuprofen may cause side effects. Some common side effects of ibuprofen include stomach pain, heartburn, nausea, and vomiting [2]. These side effects are usually mild and go away on their own. However, in some cases, ibuprofen can cause more serious side effects, such as stomach ulcers, bleeding, and kidney problems [2].

It is important to take ibuprofen as directed and not to exceed the recommended dose. Taking too much ibuprofen can increase the risk of side effects [2]. It is also important to talk to your doctor or pharmacist before taking ibuprofen if you have any medical conditions or take other medications, as ibuprofen can interact with some medications [2].

In terms of the generic version of Advil, it is important to note that generic drugs must meet the same standards for safety, effectiveness, and quality as the brand-name drug [3]. The FDA requires that generic drugs contain the same active ingredient as the brand-name drug, in the same strength and dosage form [3]. Therefore, the potential side effects of generic ibuprofen should be the same as those of brand-name Advil.

In conclusion, ibuprofen, including the generic version of Advil, may cause side effects, both mild and serious. It is important to take ibuprofen as directed and not to exceed the recommended dose. Talk to your doctor or pharmacist before taking ibuprofen if you have any medical conditions or take other medications.
