Identifying Potential Side Effects and Interactions

Consult your doctor before using generic Viagra. Common side effects include headache, facial flushing, nasal congestion, and upset stomach. These usually are mild and temporary.

Serious Side Effects

Seek immediate medical attention if you experience chest pain, sudden vision loss, or prolonged erection (priapism). These are rare but serious.

Certain medications interact with Viagra. These include nitrates (used for chest pain), alpha-blockers (used for high blood pressure), and some antifungal medications. Inform your doctor about all medications, supplements, and herbal remedies you are taking. This ensures safe usage.

Alcohol consumption can increase the risk of side effects. Limit alcohol intake while taking Viagra.

Grapefruit juice can interact with Viagra, potentially leading to increased blood levels. Avoid grapefruit juice while using this medication.
