01When a mail-order pharmacy still needs the script
A licensed mail-order house can ship 25 mg or 50 mg after it has the prescription. It cannot invent the milligram. BeSafeRx is the FDA check before a new URL gets a card number.
BeSafeRx before the cart holds that lookup. This page stops at how the US line is written and filled.
02Why 100 mg is not the first carton
Shop grids that lead with 100 mg are selling the labelled maximum, not the usual first swallow. After two clean misses at 50 mg, with arousal present and a handled meal, a prescriber may move to 100 mg. That step is a later visit.
Export 100 mg packs sit on a different vault. They do not rewrite the US start.
03How a clinic visit usually starts
The visit screens chest pain history, nitrate sprays, alpha-blockers, and HIV boosters before anyone prices a ten-count. Age 65 and older often leaves with 25 mg. A clean adult list often leaves with 50 mg.
Sudden vision loss, an erection past four hours, or chest pain on a nitrate is emergency care, not a refill request.
04What a walk-in aisle cannot do
A US grocery aisle cannot hand over Viagra the way it hands over ibuprofen. Behind-the-counter talk still ends in a prescription check. UK Viagra Connect is a pharmacy (P) medicine under MHRA, not an FDA OTC switch.
See UK Connect is not a US OTC stamp if the photo in the query is a UK carton.
05What a US pharmacy fill actually is
A licensed pharmacy receives the prescription, checks the chart for nitrates and strong CYP3A4 inhibitors, and dispenses the named tablet. Mail-order and local counters use the same rule. The bottle still has to match 25 mg or 50 mg if that is what was written.
Generic sildenafil after December 2017 is the usual US name on that bottle. Brand Viagra can still be written. Both are prescription products.
06Who writes the 25-50 mg line
The order has to name sildenafil or Viagra and a strength. For this site the featured strengths are 25 mg and 50 mg, the start band on the insert. A clinic visit, a telehealth exam that still writes a legal prescription, or a refill on an existing chart can all produce that line. A cart that never asks for a prescriber is not a US fill.
Read the sildenafil 25-50 mg vault for the start row and the nitrate stop. Sibling probe: Viagra is not in a US aisle.
