To put that into perspective, taking 25mg of klonopin would be
equivalent to taking 500mg valium - a presposterous dose, and MUCH, MUCH more than ANY reputable MD would prescribe due to concerns about respiratory and other CNS depressant effects. Very commonly combined with other CNS depressants such as alcohol, barbituates, opiods, etc. would lead to serious respiratory failure, including coma and death.
