Always consult your doctor before taking Viagra (sildenafil). The typical starting dose is 50 mg, taken as needed, about an hour before sexual activity. Your doctor may adjust this based on your response and health conditions. Don’t exceed 100 mg in a 24-hour period.
Common Side Effects
Viagra can cause headaches, flushing, nasal congestion, and upset stomach. These are usually mild and temporary. More serious, though rare, side effects include vision changes (blurred vision, blue-tinged vision), hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience any of these.
Drug Interactions
Viagra interacts with several medications. Specifically, it’s crucial to avoid combining it with nitrates (used to treat chest pain) due to the risk of dangerously low blood pressure. Inform your doctor about all medications, including over-the-counter drugs and supplements, you are taking.
