Viagra, or sildenafil, treats erectile dysfunction (ED) by increasing blood flow to the penis. This allows for firmer, longer-lasting erections during sexual stimulation. It’s important to remember Viagra only works with sexual arousal; it doesn’t create desire.
Who Can Use Viagra?
Men aged 18 and older diagnosed with ED can use Viagra, after consulting a doctor. Your physician will assess your health and determine if Viagra is suitable for you, considering potential drug interactions and health conditions like heart problems. Always follow your doctor’s prescription and dosage instructions carefully.
How Viagra Works:
Viagra blocks an enzyme called phosphodiesterase-5 (PDE5), leading to increased levels of cyclic GMP. This increased cyclic GMP relaxes blood vessel muscles in the penis, resulting in improved blood flow. This process only occurs when there’s sexual stimulation.
Potential Side Effects:
Common side effects include headache, facial flushing, nasal congestion, and indigestion. Rare but more serious side effects exist, including vision changes and hearing loss. Report any unusual symptoms to your doctor immediately. Proper medical supervision is vital to minimize risks.
