Always consult your doctor before using Viagra. Common side effects include headache, facial flushing, nasal congestion, and indigestion. Less common, but potentially serious, side effects are vision changes (blurred vision, blue tint to vision), prolonged erection (priapism), and hearing loss. If you experience a prolonged erection lasting more than four hours, seek immediate medical attention. Sudden vision or hearing loss also requires immediate medical assistance.
Drug Interactions
Viagra can interact negatively with certain medications, particularly nitrates used to treat chest pain. Combining them can cause a dangerous drop in blood pressure. Inform your doctor about all medications, including over-the-counter drugs and supplements, you are taking before starting Viagra. Grapefruit juice can also increase Viagra’s levels in your blood, potentially leading to increased side effects. Avoid grapefruit juice while using Viagra.
Health Conditions
Viagra is not suitable for everyone. Individuals with heart conditions, low blood pressure, stroke history, or retinal problems should discuss the risks with their doctor before use. Pre-existing eye conditions might worsen with Viagra use. Men with severe liver or kidney disease should also exercise caution.
