Quick Facts

What It Is and How It Works
Viagra contains the active ingredient sildenafil citrate, which is classified as a phosphodiesterase type 5 (PDE5) inhibitor. Its mechanism of action involves the relaxation of blood vessels in the penis during sexual stimulation. This results in enhanced blood flow, facilitating an erection. Importantly, Viagra does not induce an erection on its own; sexual arousal is necessary for it to be effective.
Indications / Uses
Viagra is primarily indicated for the treatment of erectile dysfunction (ED). ED can result from various causes, including psychological factors, health conditions like diabetes, or the use of certain medications. There are no widely recognized or scientifically supported off-label uses of Viagra at a 200mg dosage.
Dosage Forms and Typical Dosing Considerations
Viagra is typically available in tablet forms of 25mg, 50mg, and 100mg. The prescribing physician determines the right dosage based on individual needs and response. The higher dose of 200mg is not standard and should only be considered when advised by a healthcare provider after evaluating potential benefits and risks. Dosing may vary depending on factors like age, liver/kidney function, and concurrent medication use.
How to Take It Correctly Step-by-Step
