Do medical withdrawals look bad on a transcript for medical or pharmacy school?

I am trying to get into pharmacy school, but i dropped 4 classes last fall for medical reasons, and now im dropping again in summer A for a concussion.. Both are medical withdrawals but do they still look at this badly because of time taken off and that ive only finished 2 courses this whole year, i mean 5 MW's cant be appealing for medical school candidates.. and also are they aloud to ask you about medical withdrawals? I got off to a bad start in college and ive been trying to get my grades up this year, but i keep running into problems, its very discouraging.. i mean its hard enough getting the grades in these complicated classes but when im having to drop them for medical reasons its annoying.. but anyway, what do professional schools think about medical withdrawals?
