Viagra, like all medications, carries potential side effects. Common side effects include headache, flushing, nasal congestion, and indigestion. Less common, but still possible, are visual disturbances, such as blurred vision or sensitivity to light. Rarely, more serious side effects like prolonged erection (priapism) may occur. Seek immediate medical attention if you experience a prolonged erection lasting more than four hours.
Certain medical conditions increase the risk of side effects. Men with heart problems, low blood pressure, or a history of stroke should discuss Viagra use with their doctor carefully. Similarly, men taking nitrates for chest pain should absolutely avoid Viagra due to a potentially dangerous interaction.
Viagra interacts with several medications. This includes nitrates, as mentioned, but also alpha-blockers, often used for high blood pressure or prostate problems. Combining Viagra with these can cause a significant drop in blood pressure. Other medications may also interact; always inform your doctor of all medications, supplements, and herbal remedies you are taking before starting Viagra.
Before taking Viagra, provide your doctor with a complete medical history. This includes any pre-existing conditions and current medications. Open communication is key to safe and effective medication use.
