Can a tram driver prior to commencing work take a medicine, in which the leaflet contains the following entry "during the treatment period, do not drive"?

The information in the medicine's leaflet is an unambiguous warning that the preparation impairs the driver's psychomotor performance. In accordance with regulations, it is prohibited to drive a vehicle – including a tram – after taking a substance that acts similarly to alcohol, and a medicine with the described warning must be considered such a substance. Operating a vehicle in such a condition would pose a direct threat to road safety.
