Generic Viagra, like its brand-name counterpart, can cause side effects. Common ones include headache, facial flushing, nasal congestion, and upset stomach. These usually are mild and temporary. Less common but potentially serious side effects include changes in vision (blurred vision, blue-tinted vision), prolonged erection (priapism), and hearing loss.
Seek immediate medical attention if you experience a prolonged erection lasting more than four hours or sudden hearing loss. Vision changes warrant a doctor’s visit as well.
Certain medications interact with Viagra. Nitrates, commonly used to treat angina (chest pain), are a critical concern. Combining them with Viagra can cause a dangerous drop in blood pressure. Discuss all medications you take, including over-the-counter drugs and supplements, with your doctor before starting Viagra.
Alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can also interact, potentially leading to low blood pressure. Your doctor will help determine if Viagra is safe given your other medications.
Grapefruit juice can inhibit the metabolism of Viagra, increasing its concentration in your blood and potentially intensifying both its effects and side effects. Avoid grapefruit juice while taking Viagra.
