Ask about the 90-day supply
Daily low-dose tadalafil means a tablet every day indefinitely, which makes quantity the lever that matters most. Fixed dispensing costs spread across ninety tablets instead of thirty, and you stop having to remember monthly.
- Ask your prescriber to write for a 90-day supply where clinically appropriate.
- Ask the pharmacy for the 90-day cash price and compare it per tablet.
- Ask whether a discount card lowers it further.
- Check whether your insurance would cover any of it — usually it will not for ED, but it costs nothing to ask.
