Consult your doctor before using Viagra, especially if you have heart problems, low blood pressure, or a history of strokes. Viagra can interact negatively with certain medications, including nitrates.
Common side effects include headache, facial flushing, nasal congestion, and indigestion. These are usually mild and temporary. Less common, but more serious, side effects include vision changes (blurred vision, blue tinge), hearing loss, and prolonged erection (priapism).
If you experience a prolonged erection lasting more than four hours, seek immediate medical attention. This is a medical emergency.
Avoid alcohol consumption while taking Viagra, as it can intensify side effects. Similarly, grapefruit juice can interfere with Viagra’s metabolism.
