Viagra 100mg contains 100 milligrams of sildenafil citrate, a medication that enhances blood flow to the penis. This increased blood flow facilitates an erection in response to sexual stimulation.
Sildenafil works by inhibiting an enzyme called phosphodiesterase-5 (PDE5). PDE5 usually breaks down cGMP, a molecule crucial for achieving and maintaining an erection. By blocking PDE5, Viagra allows cGMP levels to rise, resulting in relaxed blood vessels and improved blood flow to the penis.
Important Note: Viagra only works with sexual stimulation. It doesn’t directly cause an erection; it helps your body respond to sexual stimulation more effectively.
Dosage: The 100mg dose is common, but your doctor might prescribe a lower dose (like 25mg or 50mg) depending on your individual needs and health conditions. Always follow your doctor’s instructions precisely.
Potential Side Effects: Common side effects include headache, flushing, nasal congestion, and visual disturbances. More serious, though rare, side effects include prolonged erection (priapism) and sudden vision or hearing loss. Seek immediate medical attention if you experience any concerning side effects.
Interactions: Viagra can interact with other medications, particularly nitrates. Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, before starting Viagra.
Remember: Viagra is a prescription medication. Consult your doctor to determine if it’s appropriate for you and to discuss potential risks and benefits.
