Precautions
The validity of diagnostic vitamin B12 or folic acid blood assays could be compromised by medications, and this should be considered before relying on such tests for therapy.
Vitamin B12 is not a substitute for folic acid and since it might improve folic acid deficient megaloblastic anemia, indiscriminate use of vitamin B12 could mask the true diagnosis.
Hypokalemia and thrombocytosis could occur upon conversion of severe megaloblastic to normal erythropoiesis with B12 therapy. Therefore, serum potassium levels and the platelet count should be monitored carefully during therapy.
Vitamin B12 deficiency may suppress the signs of polycythemia vera. Treatment with vitamin B12 may unmask this condition.
Pregnancy-Lactation
Pregnancy
Available data from cases reported in published literature and postmarketing surveillance in pregnant women are insufficient to identify a drug-associated risk for major birth defects, miscarriage, or adverse maternal and fetal outcomes
There are risks to pregnant woman and fetus associated with untreated cyanide poisoning
Cyanide readily crosses the placenta; cyanide poisoning is a medical emergency in pregnancy which can be fatal for pregnant woman and fetus if left untreated; life-sustaining therapy should not be withheld due to pregnancy
Lactation
Breastfeeding not recommended during treatment; there are no data to determine whenbreastfeeding may be safely restarted following administration of drug; hydroxocobalamin and Vitamin B12 (which is formed when hydroxocobalamin combines with cyanide) are present in human milk; there are no data on effects of hydroxocobalamin on breastfed infant or effects on milk production
