Medline Plus explains that when medications are broken down by the liver biotin might decrease how quickly the liver does it. If you are using biotin as a supplement, it might increase the side effects of the medicine you are taking.​(8)

Therefore, it is important to note whether you eat egg whites while taking biotin.

Lastly, if you are taking vitamin B5 (pantothenic acid) or alpha-lipoid acid while taking biotin, it will reduce the body’s absorption of the other supplement.
