⬛ Boxed warning (the FDA's strongest warning)
This is the FDA's strongest warning. NSAIDs, including ibuprofen, increase the risk of serious heart and blood vessel events, such as heart attack and stroke, which can be fatal. This risk may happen early in treatment and may grow with longer use. Ibuprofen is not to be used in the setting of coronary artery bypass graft (CABG) surgery. NSAIDs also increase the risk of serious stomach and intestine problems, including bleeding, ulcers, and holes (perforation), which can be fatal. These can happen at any time, without warning signs. Older adults are at greater risk for these stomach and intestine problems.
