I was trying to memorize the drugs in each of the FDA pregnancy categories A, B, C, D, and X.
But, then I gave up because they just don't make sense and am overwhelmed.
Can you please tell me if they are going to ask us about this
They are not gonna ask such things, trust me. I think that having some very specific examples in mind is important, though. Consider, among them, warfarin, ACE inhibitors, thalidomide, retinoic acid & isotretinoin, tetracyclines (& possibly quinolones), as general examples of drugs NOT to be prescribed under any circumastances during pregnancy. Also, consider some "safe to take" drugs, such as acetaminophen and beta-lactamic antibiotics.
