Sildenafil — Affordable ED Treatment That Works

Sildenafil is the generic form of Viagra®, the medication that redefined erectile dysfunction treatment in 1998. It contains the identical active ingredient — sildenafil citrate — at the same strengths as the brand-name product, and works through the same PDE5 inhibitor mechanism.

Since the Viagra® patent expired, generic sildenafil has become the most widely prescribed ED medication in the world. The FDA requires generics to demonstrate bioequivalence to the brand-name product: same molecule, same dose, same clinical effect — at a fraction of the price.

For most men starting ED treatment, sildenafil is the practical first choice. It is well studied, well tolerated, and the price makes it easy to try without financial pressure.

Sildenafil is a PDE5 inhibitor. It blocks the enzyme phosphodiesterase type 5 in the smooth muscle of the erectile tissue. With that enzyme suppressed, cGMP accumulates, blood vessels relax, and blood flows into the penis in response to sexual stimulation.

Sildenafil does not create an erection on its own. It creates the conditions in which an erection occurs when you are sexually aroused. No stimulation, no erection — the medication works with your natural response, not around it.

Onset is typically 30-60 minutes on an empty or light stomach. A heavy, high-fat meal can delay onset by 30-60 minutes. Effects last approximately 4-6 hours, which makes sildenafil well suited to planned encounters within a defined window.

Doses come in 25 mg, 50 mg, and 100 mg. Most providers start at 50 mg and adjust based on response and tolerance. Take one dose per 24 hours — never more.

Generic sildenafil is typically 80-90% less expensive than brand-name Viagra® — the same active ingredient at the same doses for a fraction of the price. Your provider and pharmacy will confirm final cost before you fill.
