01Why does a written line still sit on the bottle?
Organic nitrates and riociguat are contraindications. The writer has to see those rows before anyone prices 10 mg. A clerk cannot run that list from a checkout screen.
Alpha-blockers, ketoconazole, ritonavir, and creatinine clearance also change the milligram or the spacing. Those are chart facts. See how 10 mg gets written.
02Does a foreign pharmacy aisle change the US rule?
A foreign aisle does not rewrite the US Cialis label. Importing a prescription tablet for personal use is a separate legal question this page does not settle. The US fill still wants a US-licensed writer.
Barcelona travellers who arrive with a holiday strip still need a clinician to read the 10 mg start before the next US fill.
03What can a clerk not skip at pickup?
Pickup still allows the pharmacist to ask about nitrates, the last dose, and whether an alpha-blocker is already stable. That is counselling on the labelled stops, not a second diagnosis.
An erection lasting more than 4 hours is emergency care. The clerk cannot treat that at the register. See erection past four hours.
04Does HSA language make Cialis an aisle product?
HSA or FSA eligibility on a tile is a payment note. It does not move tadalafil into the open aisle. The tablet stays prescription-only.
If the questionnaire never asks about nitrates, the questionnaire is the problem. BeSafeRx still wants a licensed pharmacist on the other end.
05If a kiosk offers same-day Cialis, is that OTC?
Same-day language is stock speed. The kiosk still needs a licensed clinician's line. Speed does not create an over-the-counter stamp.
Mail-order is the same product with a slower box. Both wait on the written 10 mg as-needed order when that is the regimen.
06Is any Cialis strength OTC in the United States?
No US Cialis strength is over the counter. Film-coated tablets at 2.5, 5, 10, and 20 mg all sit behind a written line. The 10 mg as-needed start does not move that status.
A counter can hand the bottle over after the order arrives. That handoff is a fill, not an aisle sale.
