The side effect of this man's prescription drug is that it turns him into a centaur. This funny part is how nonchalant the pharmacist is about this side effect: her response is as if she sees this very unusual side effect quite regularly, and it's not a big deal. Apparently, the only action required is to be familiar with the side effect, as if it were a more benign one like drowsiness.
