Analgesics--in particular when self-prescribed or taken over the long term--may have a negative effect on safety on the road. This applies not only to vehicle drivers, but also to cyclists and pedestrians. Psychotropic effects of analgesics of all three WHO categories play a major causal role. ⋯ On the other hand, untreated severe pain has a high risk potential, since it may reduce both cognitive and psychomotoric performance. During the stabilization phase or dose adjustment of opioids, the patient must cautioned not to drive, and particular care must be taken in patients on concomitant or long-term medication or drinking excessive alcohol. In the last resort, the prescription of an analgesic is an individual decision involving both physician and patient.
