How dangerous is it to drink alcohol about 14 hours after taking two pills of lorazepam?

Lorazepam & alcohol: You did not mention dosage of lorazepam (drug comes in 3 strengths (.5, 1, and 2 mg). Half-life of this drug is 14 hours, meaning about 50% of dose is still in your system then. It is NOT a good idea to mix drugs like this (benzodiazepines) with alcohol, at all! Effects are synergistic, so magnifies effect of alcohol on your body. You could suffer serious effects, and NEVER drive on this mix!

The combination of benzodiazepines and alcohol are potentially fatal. The benzodiazepine is fat soluble and may stay in the body, so the impact, which is reactive with alcohol, can cause you to forget to breathe, or inhibit breathing. Breathing is good. Do not risk this.
