Always discuss Viagra with your doctor before use. Headaches, facial flushing, and indigestion are common side effects. Less frequent, but still possible, are nasal congestion, visual disturbances (like blurry vision or sensitivity to light), and muscle aches.
More serious, though rare, side effects include prolonged erection (priapism), sudden vision loss, and hearing loss. Seek immediate medical attention if you experience any of these.
Viagra can interact negatively with several medications. The following table provides examples:
| Nitrates (e. g., nitroglycerin) | Dangerous drop in blood pressure, potentially leading to fainting or heart attack. |
| Alpha-blockers (used for high blood pressure or prostate problems) | Increased risk of low blood pressure. |
| Certain antifungals (e. g., ketoconazole) | Increased Viagra levels in the blood, potentially increasing side effects. |
| HIV protease inhibitors (e. g., ritonavir) | Increased Viagra levels in the blood, potentially increasing side effects. |
This list is not exhaustive; other medications can also interact with Viagra. Provide your doctor with a complete list of all medications, supplements, and herbal remedies you are taking. This ensures your safety and helps determine the most appropriate treatment plan.
