it is small, white, 3/16" across, fairly thick. Z or more likely N on one side with 5 on the other. No line at all
There are at least two Canadian pills that have imprints of 5 and N (none with Z).
Prednisone 5 mg manufactured by Teva in Canada.
Each white, round, flat-faced, bevelled-edged, scored tablet, engraved "N" and "5" on one side and plain on the other, contains 5 mg of prednisone.
Prednisone is taken for a wide range of inflammatory conditions and is commonly taken for asthma.
Olanzapine 5 mg manufactured by Teva in Canada.
Each white, round, film-coated tablet, marked with "5" on one side and "N" on the other side, contains olanzapine 5 mg.
Olanzapine is used to treat schizophrenia and other conditions related to mental health.
As you say the 5 and N are on opposite sides of the pill, it is more likely to be olanzapine than prednisone. You could check and see if the pill matches the rest of the description - film coated and the imprint marked on the pill (as opposed to engraved).
A lot of the Canadian generics have similar descriptions, so there may be other pills out there as well.
