On this episode, I discuss folic acid pharmacology, clinical pearls, and important drug induced causes of deficiency.
Folic acid deficiency can be caused by medications like phenytoin and methotrexate.
Urinary tract infections can lead to the use of trimethoprim and if used chronically can increase the risk of folic acid deficiency.
Normal folic acid levels range from 2-20 ng/mL but can vary a little bit based upon the lab that the level is drawn in.
