Sildenafil citrate, the active ingredient in Viagra, works by increasing blood flow to the penis. This happens because it inhibits an enzyme called phosphodiesterase-5 (PDE5), allowing nitric oxide to relax the blood vessels. This increased blood flow facilitates an erection in response to sexual stimulation.
Dosage: The typical starting dose is 50mg, taken as needed, about an hour before sexual activity. Your doctor may adjust this based on your response and medical history. Never exceed the recommended dose.
Important Note: Sildenafil is not a performance enhancer. It won’t create an erection without sexual stimulation. It only helps achieve and maintain an erection if there is already sexual arousal.
Side Effects: Common side effects include headaches, facial flushing, nasal congestion, and indigestion. More serious, though rare, side effects include vision changes and sudden hearing loss. Seek immediate medical attention if you experience these.
Interactions: Sildenafil interacts with certain medications, particularly nitrates. Taking them together can cause a dangerous drop in blood pressure. Inform your doctor of all medications you are taking before starting sildenafil.
Contraindications: Sildenafil is not suitable for everyone. Individuals with heart conditions, uncontrolled high blood pressure, or a history of stroke should avoid it. Pre-existing eye conditions may also be a contraindication.
Consult Your Doctor: Before using sildenafil, schedule a consultation with your physician. They will assess your health status and determine if it’s safe and appropriate for you. They can also help manage potential side effects and interactions.
