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.
Sources: FDA label information (DailyMed)
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.
Coupon or manufacturer program?#
A US generic exists, which is exactly the situation discount cards are good at. Prices move daily by pharmacy and postcode, and the spread between the cheapest and dearest pharmacy in one town is routinely several times the drug's actual cost. Flat-rate cash pharmacies are the other half of this comparison and frequently win outright.
Watch for the same coupon quoting different prices at two pharmacies a mile apart — that is normal, and it is why checking twice pays.
The full reasoning, including why "as low as" banners usually quote someone else's discount, is in the coupon analysis.

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.
