There are rare cases of Biotin side effects. In one such case a large dose of Biotin was being taken along with B5. In this one case it did cause a life-threatening illness. But when the consumption of the vitamins was stopped the disease also ceased. It is not known if it was the combination of the two being taken together, or just large amounts of the B-vitamins which caused the near fatality.


Other than these rare instances there are no known biotin side effects. The reasons for these isolated Biotin side effects were either prolonged doses or over use of Biotin.
