Before using Viagra, understand potential side effects. Common ones include headache, facial flushing, nasal congestion, and upset stomach. Less common, but still possible, are visual disturbances (blurred vision, sensitivity to light), dizziness, and hearing problems. Serious side effects, though rare, include prolonged erection (priapism) requiring immediate medical attention. Always consult your doctor if you experience any concerning symptoms.
Common Drug Interactions
Viagra interacts with several medications. Nitrate medications (used to treat chest pain) are a serious concern, as combining them can dangerously lower blood pressure. Other medications that can interact include alpha-blockers (used for high blood pressure and prostate problems), antifungal medications (like ketoconazole and itraconazole), and HIV protease inhibitors. Always inform your doctor about all medications, supplements, and herbal remedies you take.

This information is not exhaustive. Consult your physician or pharmacist for a complete list of potential drug interactions and for personalized advice. They can help determine if Viagra is safe and appropriate for you, considering your individual medical history and current medications.
Additional Considerations
Grapefruit juice can also affect how Viagra is processed by your body and should be avoided. Alcohol consumption can also increase the risk of certain side effects. Open communication with your healthcare provider is key to safe and effective use.
