Viagra, the brand name for sildenafil citrate, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection in response to sexual stimulation. This improved blood flow is achieved through the inhibition of an enzyme called phosphodiesterase-5 (PDE5).
Who Can Use Viagra?
Viagra is generally prescribed for men aged 18 and older experiencing ED. However, it’s crucial to consult a doctor before use, as certain health conditions, medications, or allergies may preclude its use. Your physician will assess your overall health and determine if Viagra is safe and appropriate for you.
Potential Side Effects & Interactions
Common side effects include headaches, flushing, nasal congestion, and visual disturbances. Less common, but more serious, side effects can include heart problems. It’s important to disclose all medications you’re taking to your doctor, as Viagra can interact with nitrates and certain other drugs. This interaction can be dangerous.
