Can viagra cause bleeding or blood in stool?
Based on the search results, there is evidence that Viagra may lead to rectal bleeding or blood in stool, although it is a less frequent occurrence. A study found that rectal bleeding has been reported as a side effect of sildenafil therapy in adult patients. However, it's worth noting that not all patients experience this side effect, and it is less common compared to other side effects like headache, flushing, or diarrhea. If any side effects, including rectal bleeding or blood in stool, are observed, it is important to seek appropriate attention. Other serious side effects of Viagra include low blood pressure, abnormal ejaculation, and prolonged erections lasting more than 6 hours. It is crucial to use Viagra as directed and inform the healthcare provider about any preexisting medical conditions or medications to avoid potential interactions or adverse effects.
