WARNINGS Avoid the intravenous route. Folic acid is not a substitute for vitamin B 12 although it may improve vitamin B 12 deficient megaloblastic anemia. Exclusive use of folic acid in treating vitamin B 12 deficient megaloblastic anemia could result in progressive and irreversible neurologic damage. Blunted or impeded therapeutic response to vitamin B 12 may be due to such conditions as infection, uremia, drugs having bone marrow suppressant properties such as chloramphenicol, and concurrent iron or folic acid deficiency.
