You can but only certain wormers. I know you CAN'T use Equest Pramox and there are some others you can't use. Ask where you're buying it from and they'll be able to tell you. It will say on the instruction leaflet (and probably on the box) if you can give it to pregnant and lactating mares. Websites often say if they're suitable as well if you look at the detail on each wormer. You will also need to be careful when the foal arrives as they can only have certain wormers up to about six months old.
