Consult your doctor before using Viagra, especially if you have heart problems, low blood pressure, or a history of strokes. Viagra can lower blood pressure, potentially causing dizziness or fainting. This risk increases when combined with nitrates found in some heart medications. Avoid concurrent use.
Common Side Effects
Common side effects include headache, facial flushing, nasal congestion, and visual disturbances (blurred vision, sensitivity to light). These are usually mild and temporary. More serious side effects, though rare, include prolonged erection (priapism), requiring immediate medical attention. Stomach upset is also possible.
Drug Interactions
Besides nitrates, Viagra interacts with certain antifungal medications (like ketoconazole), HIV protease inhibitors (like ritonavir), and some antibiotics. These interactions can increase Viagra’s concentration in the blood, potentially leading to increased side effects. Always inform your doctor about all medications you’re taking, including herbal supplements.
Alcohol Consumption
Excessive alcohol consumption can worsen Viagra’s side effects. Moderate alcohol intake is generally acceptable, but excessive use should be avoided.
