A 39-year-old member asked:

Can I get pregnant or have surgery while taking warfarin?

Pregnant not advised: Warfarin is known to cause birth defects (fetal warfarin syndrome) if used in the first trimester, and neurological defects if used in the second and third trimesters. Women on warfarin should use reliable birth control. If someone taking warfarin wants to become pregnant, she should consult with her OB doctor before pregnancy to discuss alternate medications.

Yeah - it's slightly more complicated than that, but the gist of it is as he says - coumadin is generally a no-no in pregnancy.

Yes: Warfarin is the most common drug to show a change in effectiveness with the use of herbal supplements. Among them, st. John's wort and ginko biloba are the most commonly reported to interact with warfarin, the first increases the risk of clotting while the second increases the risk of bleeding.

A 42-year-old member asked:

Could stopping treatment with Coumadin (warfarin) cause nightmares?

Dr. Mark Hoepfner

Not likely: I am not aware of Coumadin (warfarin) causing nightmares. It has a fairly specific function to thin the blood or prevent blood clotting. If one was on coumadin, (warfarin) maybe there had been other medications that caused changes, or it is just a coincidence.
