Pediatric Patients: Klonopin is administered orally. In order to minimize drowsiness, the initial dose for infants and children (up to 10 years of age or 30 kg of body weight) should be between 0.01 and 0.03 mg/kg/day but not to exceed 0.05 mg/kg/day given in two or three divided doses.
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.
