Always take Viagra exactly as prescribed by your doctor. The recommended starting dose is 50 mg. Your doctor may adjust this based on your response and health conditions.
Viagra should be taken approximately 1 hour before sexual activity. Avoid consuming large or fatty meals before taking it, as this can delay its onset of action. Alcohol consumption can also reduce effectiveness; moderate your intake.
Common side effects include headache, flushing, nasal congestion, and visual disturbances. These are usually mild and temporary.
More serious, though rare, side effects include:
| Prolonged erection (priapism) | Painful erection lasting more than 4 hours. | Seek immediate medical attention. |
| Sudden vision loss | Complete or partial loss of vision. | Stop taking Viagra and contact your doctor immediately. |
| Hearing loss | Sudden decrease or loss of hearing. | Stop taking Viagra and contact your doctor immediately. |
| Heart attack or stroke | Chest pain, shortness of breath, weakness. | Call emergency services immediately. |
Viagra interacts with certain medications, including nitrates. Inform your doctor about all medications, supplements, and herbal remedies you are taking. This includes those for high blood pressure or heart conditions. People with severe heart or liver disease, uncontrolled high blood pressure, or a history of stroke should not take Viagra.
If you experience any concerning side effects, discontinue use and consult your physician promptly. They can provide personalized guidance based on your specific health needs.
