yes..I'd be curious to know what slice of the hep B market is accounted for by pregnant women. I bet it's larger than one might think due to the fact that treatment may be indicated to decrease vertical transmission even in situations where therapy might not otherwise be mandatory..hep B testing is also a routine part of the prenatal/perinatal assessment so pickup is high
when i did OB I prescribed plenty of category C drugs in pregnancy, although if an equivalent category B alternative was available that automatically became the default treatment of choice (for medical-legal reasons as much as anything)
