Viagra, or sildenafil, primarily works by increasing blood flow to the penis, facilitating an erection. This happens through the inhibition of an enzyme called phosphodiesterase-5 (PDE5).
Desired Effects
The intended effect is improved erectile function, allowing for firmer and longer-lasting erections sufficient for sexual intercourse. This improvement is typically noticed within 30-60 minutes of taking the medication. The duration of the effect varies, but generally lasts for several hours.
Potential Side Effects
Common side effects include headache, facial flushing, nasal congestion, and indigestion. These are usually mild and temporary. Less common, but more serious, side effects can include vision changes (blurred vision, blue tinge to vision), hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience a prolonged erection (lasting more than four hours) or sudden hearing or vision loss.
Important Considerations
Viagra interacts with certain medications, particularly nitrates. Combining them can cause a dangerous drop in blood pressure. Discuss all your medications with your doctor before starting Viagra. Certain health conditions, such as heart disease, can also influence the suitability of Viagra. Your doctor will assess your individual risk factors and determine if Viagra is appropriate for you. Always follow your doctor’s prescribed dosage and instructions.
