At purpose with the expressed infringement of function of a liver and nervous - muscle transfer (myopathy ) the constant medical control and, probably, decrease of a dose is necessary for patients. With care to apply in an operating time to drivers of vehicles and people which trade is connected to the raised concentration of attention (drops reaction rate), it is recommended to exclude reception of alcohol
