With alcohol, there is further central nervous system depression and the lethal dose can be far less. Though for it (combination and alcohol)data are not available.
For example, the maximum dose of Ativan is 10 mg/day (but doctors can prescribe more). The maximum dose of Valium is 40 mg/day. And doctors might go above 40 mg of Valium but not to 100 mg, the equivalent to Ativan. Xanax is the worst, 0.5 mg of Xanax is equal to 10 mg of Valium.
