Sildenafil: cost, evidence, and the honest comparison
The original PDE5 inhibitor. It works on the same pathway as tadalafil but with a shorter duration, which is why it is typically taken ahead of activity rather than daily.
What it's approved for
Erectile dysfunction; separately, at different doses under another brand, pulmonary arterial hypertension.
What the research actually shows
Two decades of post-approval use make sildenafil one of the best-characterised drugs in its class, and generic competition has made it one of the cheapest.

Side effects, stated plainly
Headache, flushing, indigestion, and visual disturbances are commonly reported. The nitrate contraindication is absolute and serious.
What it costs
The clearest markup exhibit on this site: the same generic tablet costs about $0.22 at itemised cash pricing and up to $10 a dose through subscription telehealth — a spread of roughly 45 times for identical medicine.

Common questions
Why is sildenafil so much cheaper at some pharmacies?
Because the medicine itself is inexpensive — itemised pricing shows cents per tablet — and what varies is what is bundled around it: the prescriber visit, packaging, subscription convenience, and discretion. Our tables separate those costs.
