Is it safe to take lorcet (hydrocodone and acetaminophen) while pregnant?

Yes but... Experienced obstetricians can deal with pregnant women on opiates, but the question is how much are you taking and do you want your newborn to go through withdrawls. Super- colic will probably have a subtle but real impact on a baby's life. Be very honest with your obstetrician and have a good plan about this issue.
