Viagra, while effective for many, can cause side effects. Common ones include headache, flushing, nasal congestion, and upset stomach. Less common, but still possible, are visual disturbances like blurred vision or sensitivity to light, and dizziness. Rarely, more serious side effects like prolonged erection (priapism) or sudden vision or hearing loss occur. Seek immediate medical attention if you experience any of these.
Side Effects Requiring Immediate Medical Attention
Priapism, a persistent and painful erection lasting more than four hours, needs immediate medical help. Similarly, sudden vision or hearing loss demands urgent attention. These are serious complications that require prompt medical intervention.
Drug Interactions
Viagra interacts with several medications. Combining it with nitrates, often used to treat chest pain, can cause a dangerous drop in blood pressure. Simultaneous use with certain heart medications, alpha-blockers (used for high blood pressure or prostate problems), or antifungal medications can also lead to adverse effects. Always inform your doctor about all medications, supplements, and herbal remedies you are taking before starting Viagra.
