Viagra, while generally safe and effective for many men, can cause side effects. These vary in severity and frequency.
Common side effects often resolve on their own and include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary.
Less common, but more serious side effects require immediate medical attention. These include:
| Prolonged erection (priapism) | An erection lasting more than four hours. | Seek immediate medical help; this is a medical emergency. |
| Sudden vision loss | Partial or complete loss of vision. | Stop taking Viagra and contact your doctor immediately. |
| Sudden hearing loss | Partial or complete loss of hearing. | Stop taking Viagra and contact your doctor immediately. |
| Heart attack or stroke | Chest pain, shortness of breath, weakness, or slurred speech. | Call emergency services immediately. |
| Low blood pressure | Dizziness, lightheadedness, fainting. | Lie down and seek medical attention. |
This list isn’t exhaustive, and individual reactions can vary. Always discuss potential side effects with your doctor before starting Viagra.
If you experience any unusual or concerning side effects, contact your healthcare provider promptly. They can provide personalized advice and assess your situation.
