sildenafil citrate

How long does Sildenafil Citrate stay in your body?

The elimination half-life of sildenafil citrate is about 4 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. Sildenafil's active N-desmethyl metabolite also has a terminal half-life of about 4 hours, so it is not materially longer. In older adults and in people with significant kidney or liver impairment, the label reports reduced drug clearance and higher blood levels (AUC/Cmax) of sildenafil — the label does not state the half-life itself is longer.

This is general information, not medical advice. It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.

How much does Sildenafil Citrate cost?

Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.11 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
