Consult your doctor to determine the appropriate dosage for you. Typically, the recommended starting dose is 50mg, taken as needed, about an hour before sexual activity. Your doctor may adjust this based on your response and individual health conditions. Never exceed 100mg in a 24-hour period.
Common Side Effects
Possible side effects include headache, flushing, nasal congestion, and upset stomach. These are usually mild and temporary. More serious side effects, though rare, include vision changes (blurred vision, blue-tinted vision), prolonged erection (priapism), and hearing loss. Seek immediate medical attention if you experience any of these serious side effects.
Precautions
Viagra is not suitable for everyone. Do not take Viagra if you have heart problems, low blood pressure, a history of stroke, or are taking certain medications, especially nitrates. Inform your doctor about all medications and supplements you are taking. Alcohol consumption can intensify side effects. Do not take more than one dose per day.
Medication Interactions
Viagra interacts with several medications. Discuss potential interactions with your physician before using Viagra, especially if you are using nitrates, alpha-blockers, or other heart medications. This is crucial for your safety.
