Always consult your doctor to determine the correct Viagra dosage for you. Typical starting doses range from 25mg to 100mg, taken as needed, about an hour before sexual activity. Your doctor will adjust the dosage based on your response and health conditions.
Common side effects include headache, facial flushing, nasal congestion, and indigestion. These are usually mild and temporary. Less common side effects include vision changes (blurred vision, sensitivity to light), and back pain.
Serious side effects are rare but require immediate medical attention. These include prolonged erection (priapism), sudden vision loss, or hearing loss.
| Headache | Common | Usually resolves on its own. Over-the-counter pain relievers may help. |
| Facial Flushing | Common | Drink plenty of water. Should subside naturally. |
| Nasal Congestion | Common | May use saline nasal spray if bothersome. |
| Indigestion | Common | Avoid large meals before taking Viagra. |
| Prolonged Erection (Priapism) | Rare | Seek immediate medical help. This is a medical emergency. |
| Sudden Vision Loss | Rare | Seek immediate medical help. |
| Sudden Hearing Loss | Rare | Seek immediate medical help. |
Do not take Viagra with nitrates or other medications that lower blood pressure. Inform your doctor about all medications you are currently taking, including herbal supplements. Alcohol can also interact with Viagra, potentially intensifying side effects. Follow your doctor’s instructions carefully for safe and effective use.
