Benzos and narcotics (downers, e.g. alcohol, ketamine, GHB)
Never use benzodiazepines in combination with alcohol, ketamine, GHB or other downers. The combination could put you in a coma, stop breathing or choke on your own vomit. This combination can also lead to unpredictable and reckless behavior with all the associated risks.
Benzos and other medicines
Do not combine benzodiazepines with drugs that lower consciousness: such as antipsychotics, other benzodiazepines or sleeping pills or antihistamines. The combination of these agents can cause an extra lowering of your consciousness.
