Could Aleve cause an intestinal bleed?

Yes, Aleve (naproxen) can potentially cause intestinal bleeding, as it is a nonsteroidal anti-inflammatory drug (NSAID). NSAIDs can irritate the gastrointestinal lining and increase the risk of ulcers and bleeding, particularly with long-term use or in individuals with certain risk factors, such as a history of ulcers or concurrent use of other medications. It's important to use Aleve as directed and consult a healthcare provider if you have concerns about gastrointestinal risks.
