01Why kitchen halves are not a fourth tablet
US film-coated diamonds are not designed as a scored 50 mg substitute. Uneven fragments wreck the coat and the milligram. If 50 mg is prescribed, price 50 mg. If 25 mg is prescribed, price 25 mg.
A split 100 mg tablet is not the 25-50 band this vault follows.
02What 25 mg and 50 mg this vault follows
50 mg is the usual start. 25 mg is the consider-start and the ritonavir cap. Featuring both keeps the step-down in the same band as the usual first swallow.
Label start 50, featured 25-50 is that job. This page only names the three tablets.
03What the diamond marks name
Brand tablets are blue, film-coated, rounded diamonds. One face says PFIZER. The other says VGR25, VGR50, or VGR100. Do not repeat those three codes as a second list after they are named.
Generic imprints differ by manufacturer. Read the milligram on the pharmacy label, not a forum color chart.
04When a script should match the bottle
A prescription for 50 mg should not be filled by splitting a 100 mg diamond. A prescription for 25 mg should not be filled by hoping a 50 mg half is even.
Featured milligrams on the sildenafil 25-50 mg vault are still 25 and 50. Generic after December 2017 is when those three strengths became generic in the US.
05How 100 mg is the labelled ceiling
Based on effectiveness and toleration, the dose may be increased to a maximum of 100 mg. That is a later visit after a real 50 mg trial, not a fourth imprint you invent at home.
Side effects that already dominate at 50 mg will not improve at 100.
06Which three US tablets exist
The insert supplies 25 mg, 50 mg, and 100 mg. Revatio 20 mg is a different product and a different indication.
Generic bottles use their own imprints. The milligram still has to be one of those three for ED.
