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.
ADVERSE REACTIONS Mild transient diarrhea, itching, transitory exanthema, feeling of swelling of entire body, and anaphylaxis. A few patients may experience pain after injection of hydroxocobalamin. To report SUSPECTED ADVERSE EVENTS, contact Actavis at 1-800-272-5525 or FDA at 1-800-FDA-1088 or http://www.fda.gov/ for voluntary reporting of adverse reactions.
