The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Cyanocobalamin falls into category C.There are no well-controlled studies that have been done in pregnant women. Cyanocobalamin should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.

However, vitamin B12 is an essential vitamin and requirements are increased during pregnancy. Amounts of vitamin B12 that are recommended by the Food and Nutrition Board, National Academy of Science-National Research Council for pregnant women (4 mcg daily) should be consumed during pregnancy.
