Interaction with other drugs
Alcohol should not be consumed during the use of the drug due to the possibility of psychomotor inhibition and respiratory depression. The drug should not be combined with phenothiazine neuroleptics due to potentiation of the depressant effect on respiration. It should be noted that cimetidine can increase the concentration of benzodiazepines (except oxazepam and lorazepam) in the blood by 50%, slowing down their metabolism and clearance. High doses of caffeine, including in beverages, can reduce the therapeutic effect of the drug.
