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).
Common side effects include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary. More serious, though rare, side effects include vision changes (blurred vision, blue tint), hearing loss, and chest pain. Seek immediate medical attention if you experience any of these.
The medication’s effectiveness varies depending on individual factors such as overall health and the cause of erectile dysfunction. Your doctor can assess these factors and determine if Viagra is the right treatment for you.
Viagra interacts with certain medications, particularly nitrates used to treat heart conditions. Combining them can cause a dangerous drop in blood pressure. Always inform your doctor about all medications you are taking before starting Viagra.
Dosage is typically 50mg, but your doctor may adjust this based on your response and health. Follow your doctor’s instructions precisely. Do not exceed the recommended dose.
Remember, Viagra is a prescription medication. Consult your doctor to discuss its suitability for you and to address any concerns you may have.
