Doxylamine had to be printed from two plates as the distance between each spot did not leave enough space for one plate to be inked up efficiently. Therefore, two plates were made, with only every other spot on each plate, giving the printers enough room to ink up the plate. For Cephalothin, in which the concentric pattern of spots left even less space between each individual circle of spots, three plates had to be used for printing. Doxylamine is a sedating antihistamine, which on its own can be used as a short-term sedative. Cephalothin is an antibiotic preventing bacteria from forming adequate cell walls.
