Expert: Dr. Arun Phophalia replied 5 years ago. Greetings. In a study the average lethal dose for Xanax has been found as 22 mg. But death can occur at 10 mg single dose. 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.
3mg klonopin was no where near as effective as 20mg valium for me. I was also on xanax for many years. 1 mg xanax = 10 mg valium but 2 mg a day xanax isn't as good as 20 mg a day of valium because it doesn't last as long. Now I would say xanax is better if I could get 3 or 4 mg a day instead of 30 or 40 mg valium because how long it lasted wouldn't be an issue.
