If you have a prescription you can get if filled in the north. My prescription used to be €55 a month in a chemist down here. Same thing was £12 in the north! I think the DPS is €144 per month per family/household, so you can get the card in your name and use it for the little fella. When I got mine I filled in the form in the chemist. Just need your PPS number from what I remember.
