The way it was written indicated that the drug was the cause.
So, I was wondering what drug it was to see what drug could cause such a birth defect.
There are quite a few drugs which are known to cause birth defects. For example a woman of child bearing age who is prescribed Accutane most sign an affidavit that she will use two methods of Birth Control while on the medicine. I think Linksalot meant the woman was on a high blood pressure medication.
