Viagra, or sildenafil, primarily treats erectile dysfunction (ED), helping men achieve and maintain an erection firm enough for satisfactory sexual intercourse. It works by increasing blood flow to the penis.
Who Can Use Viagra?
Viagra is prescribed for adult men diagnosed with ED. Your doctor will assess your medical history and current health to determine suitability. Certain conditions, such as heart problems or low blood pressure, may preclude its use. Always consult your physician before starting any medication.
How Viagra Works
Viagra inhibits an enzyme called phosphodiesterase-5 (PDE5). This enzyme usually breaks down a substance called cyclic GMP, which is crucial for penile erection. By blocking PDE5, Viagra allows cyclic GMP to remain active longer, leading to improved blood flow and stronger erections.
Dosage and Side Effects
Your doctor will determine the appropriate dosage. Common side effects include headaches, flushing, nasal congestion, and visual disturbances. Serious side effects are rare but require immediate medical attention. The information provided here is not a substitute for professional medical advice.
