What the script is actually screening
Nitrates, riociguat, severe renal impairment, and potent CYP3A4 inhibitors are why a clerk cannot hand over 5 mg. Daily use keeps plasma present every day. The interaction list does not take Sundays off.
Priapism past four hours, sudden vision change, and sudden hearing loss are label emergencies. An aisle sale has no place to put those instructions next to a cash register.
Shops that ship 5 mg and skip the visit
A site that never asks about chest-pain sprays is not filling the labeled product under US rules this board uses. Counterfeit risk sits on those carts. This scan will not map them.
Telehealth that actually writes a prescription is still a prescription path. It is not OTC. The difference is the clinician's name on the order, not the courier.
Why the US aisle still does not hold 2.5-5 mg
Cialis tablets are a prescription drug in the United States at every labeled strength, including the daily 2.5 mg and 5 mg rungs. Walking up to a shelf does not replace the nitrate and interaction screen.
Other countries have run pharmacy-supply tadalafil programs. That does not rewrite the US Cialis label this scan uses. A Toronto reader buying in the US still needs a lawful script. See getting a written line.
Supplements that print the word tadalafil
US dietary supplements are not FDA-approved Cialis. Some have been found to hide PDE5 drug substance. That is a contaminated product, not a generic 2.5 mg tablet. Do not treat the dose as known.
If a bottle promises 'the same as daily Cialis' without a prescription strength on a pharmacy label, it is not the product on the tadalafil panel.
Do not import another country's pharmacy story
Pharmacy-only tadalafil exists in some health systems. The US daily 2.5-5 mg lock on this site is still Rx. Mixing those rules is how men buy an unvetted blister and call it Cialis.
If you already have a US daily bottle, the next job is the clock, not an aisle upgrade. The same-time scan covers the swallow hour.
What a pharmacist can still refuse at the window
Even with a script, a pharmacist can hold a fill when the list shows a nitrate or when the directions say 20 mg daily. Daily ceiling on the ED label is 5 mg. That refusal is the label, not a mood.
Clearance under 30 mL/min is another hold. Ask them to call the prescriber rather than cutting a 20 mg tablet into homemade daily slivers.
