Found a small yellow tablet with no box. Before I guess, here is everything I can see.

Enteric coatings should not be crushed, and the pellets are the delivery mechanism rather than filler.

Genuine cartons have print that aligns to the die cut. Copies drift by a millimetre or so.

Reagent tests are a screen, not an assay. They rule a family in or out and say nothing about dose.

A scored oval with a two-letter code is usually a generic but the code is manufacturer-specific.

Any ideas welcome, and I will report back what the pharmacist says.
