Done a brief bit of searching and reading. Strangely I couldn’t find an image of one of these tablets but they were described ,as said, as half white half yellow and containg Cetirizine HCl 5 mg and Pseudoephedrine HCl 120 mg as the active ingredients. They are listed here, along with a longer list of inactive ingredients.

It would make sense for the 2 active ingredients to be in the seperate halfs of the pill but which is in which half you’d need to do some testing of your own to find out. On top of that, even if you get the half containing the pseudo, you still have all the inactive crap contained in the half as well as the pseudo.
