Consult your doctor before using Viagra, especially if you have heart problems, high or low blood pressure, liver or kidney disease, or a history of stroke. Viagra can interact negatively with certain medications, including nitrates. This combination can cause a dangerous drop in blood pressure.
Common Side Effects
Common side effects include headache, facial flushing, nasal congestion, and indigestion. These usually are mild and temporary. More serious, though less frequent, side effects involve vision changes (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.
Less Common but Serious Risks
Rare but potentially serious side effects include heart attack, stroke, and irregular heartbeat. While rare, these risks are more pronounced in individuals with pre-existing cardiovascular conditions. Your doctor can assess your individual risk factors.
Remember to follow your doctor’s instructions carefully regarding dosage and frequency. Never exceed the recommended dose. If you experience any concerning side effects, contact your doctor or seek medical help immediately.
