Generic Viagra, like its brand-name counterpart, can cause side effects. These vary in severity and frequency. Common ones include headache, facial flushing, nasal congestion, and indigestion. These usually are mild and temporary.
More serious, though less common, side effects demand immediate medical attention. These include:
| Sudden vision loss | Complete or partial loss of sight in one or both eyes. | Seek immediate medical help. |
| Hearing loss | Sudden decrease or loss of hearing. May be accompanied by ringing in the ears (tinnitus). | Seek immediate medical help. |
| Prolonged erection (priapism) | Erection lasting more than 4 hours. | Seek immediate medical help. This is a medical emergency. |
| Chest pain | Pain or pressure in the chest, radiating to the arm or jaw. | Seek immediate medical help. This may indicate a heart problem. |
| Stroke | Sudden weakness or numbness on one side of the body, confusion, difficulty speaking. | Seek immediate medical help. This is a medical emergency. |
Before taking generic Viagra, discuss potential risks with your doctor, especially if you have heart problems, high blood pressure, low blood pressure, liver or kidney disease, or bleeding disorders. They can help assess your suitability and advise on appropriate dosage.
Always purchase medication from reputable sources to minimize the risk of counterfeit drugs, which may contain harmful ingredients.
