Always discuss Viagra with your doctor before use. Common side effects include headache, flushing, nasal congestion, and upset stomach. Less common, but more serious, effects include vision changes (blurred vision, sensitivity to light), hearing loss, and prolonged erection (priapism). Seek immediate medical attention for priapism or any sudden vision or hearing changes.
Medication Interactions
Viagra interacts with several medications. This interaction can either reduce Viagra’s effectiveness or increase the risk of side effects. Avoid combining Viagra with nitrates (used to treat chest pain) as this combination can cause a dangerous drop in blood pressure.
Similarly, caution is advised with alpha-blockers (used to treat high blood pressure and enlarged prostate), antifungal medications (like ketoconazole and itraconazole), and certain HIV medications (like ritonavir). These medications can amplify Viagra’s effects, increasing the likelihood of side effects. Your doctor can help determine if Viagra is safe for you, given your current medications.
