I wasn't told how low, probably because I didn't ask, and don't know which white cells are low, but I've been researching online and found that the Antibotic Doxycycline 100mg my doctor put me on 30 days prior to the test can cause
a drop in the WBC
. I stopped taking it when I started the Accutane and now I really annoyed of all the worrying I'm doing. The accutane is working great, BTW. I'm 27 female in great shape, don't drink or smoke.
