Yes, Advil (ibuprofen) can cause severe allergic reactions, although such cases are rare. These allergic reactions can include symptoms such as hives, facial swelling, asthma, and shock [1]. In rare instances, these allergic reactions can be life-threatening [1].

It is important to note that while Advil is a widely used over-the-counter medication, it can still cause adverse reactions in some individuals. Therefore, it is always recommended to consult with a healthcare professional before starting any new medication, including Advil [1].

If you experience any symptoms of an allergic reaction after taking Advil, seek immediate medical attention [1].
