Viagra, like all medications, carries potential side effects. Common ones include headache, flushing, nasal congestion, and upset stomach. Less common but more serious side effects include vision changes (blurred vision, blue-tinted vision), hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience a prolonged erection lasting more than four hours.
Certain health conditions increase the risk of side effects. For example, men with heart problems should discuss Viagra use with their doctor. Existing conditions like low blood pressure or a history of stroke may also influence your suitability for this medication.
Several medications interact with Viagra. Nitrates, commonly used to treat angina, are a significant concern. Combining these drugs can cause a dangerous drop in blood pressure. Other medications, including some antifungals and antibiotics, may also affect Viagra’s effectiveness or increase the risk of side effects. Always inform your doctor about all medications, supplements, and herbal remedies you take.
Before starting Viagra, provide your doctor with a complete medical history, including details on current and past illnesses. This allows your doctor to accurately assess the risks and benefits, ensuring safe and appropriate use.
