What It Is and How It Works
Viagra is a medication that helps to treat erectile dysfunction by increasing blood flow to the penis. The active ingredient, sildenafil citrate, inhibits the enzyme phosphodiesterase type 5 (PDE5). By inhibiting PDE5, Viagra promotes the vasodilation effect of nitric oxide, a natural chemical in the body that relaxes muscles in the penis and increases blood flow, allowing men to achieve and maintain an erection when sexually stimulated.
Indications / Uses
Viagra is primarily prescribed for the treatment of erectile dysfunction. It is indicated for men experiencing difficulties in achieving or maintaining an erection sufficient for satisfactory sexual performance. While there may be off-label uses, such as for certain circulatory conditions, these should be explored solely under a healthcare provider\’s guidance.
Dosage Forms and Typical Dosing Considerations
Viagra is commonly available in tablet forms of 25 mg, 50 mg, and 100 mg. A 200 mg dose is not a standard dosage for Viagra and may not be advisable unless specifically directed by a healthcare provider, typically in cases where the benefits outweigh potential risks. Patients should adhere strictly to the prescribed dosage and consult their healthcare provider for adjustments, especially if they have underlying health conditions or are taking other medications that might interact with sildenafil.
How to Take It Correctly Step-by-Step
- Take Viagra approximately 30 to 60 minutes before sexual activity.
