There are no reported side effects from excessive biotin consumption. Excess biotin is excreted in the urine.
The Daily Value for biotin is 30mcg. The average diet supplies 28mcg. to 42mcg. of biotin daily and bacteria in the intestine also contribute biotin to the body. Long-term use of antibiotics interferes with the production of biotin in the intestine and might increase the risk of deficiency. Consuming large quantities of raw egg whites can inhibit the absorption of biotin and result in deficiency of biotin.
