Is it possible to use supplements and ointments with vitamin A with Izotek?

During the treatment with Izotek, preparations containing vitamin A should not be used, including hair tablets, where vitamin A is in the composition or eye ointment with vitamin A. Isotretinoin contained in Izotek is a derivative of vitamin A. When combining Izotek and products with vitamin A, hypervitaminosis A could occur, which increases the risk of overdose and toxic effects of this vitamin on the body.
