Viagra, while effective for many, can cause side effects. Common side effects include headache, flushing, nasal congestion, and visual disturbances like blurred vision or sensitivity to light. These usually are mild and temporary.
More serious, though less common, side effects include chest pain, irregular heartbeat, and sudden vision loss. Seek immediate medical attention if you experience any of these. Prolonged or painful erection (priapism) is another serious side effect requiring immediate medical help.
Medication Interactions
Viagra interacts with certain medications. Combining it with nitrates, often used to treat chest pain, can cause a dangerous drop in blood pressure. Similarly, alpha-blockers, commonly prescribed for high blood pressure or prostate problems, can also interact negatively. Always inform your doctor about all medications, including over-the-counter drugs and supplements, you’re taking before starting Viagra.
Other Important Considerations
Certain health conditions can increase the risk of side effects. These include heart disease, stroke, high blood pressure, and liver or kidney problems. Open communication with your doctor is paramount before using Viagra.
