How much Lorazepam can kill you? What if you mix it with alcohol?
Lorazepam is not usually fatal in overdose, but may cause fatal respiratory depression if taken in overdose with alcohol. But it CAN be lethal. Signs of overdose range through mental confusion, dysarthria, paradoxical reactions, drowsiness, hypotonia, ataxia, hypotension, hypnotic state, coma, cardiovascular depression, respiratory depression and death.
The usual range is 2 to 6 mg a day, so I assume anything over that can kill you as that would be an overdose. Lorzepam would lead to death by respiratory arrest, which is the cessation of breathing..
