Whats the highest mg klonopin?

Depends. if using it alot you will get tolerant so can take more but usually 2 mg dose is alot , max 4 mg/day and if combine with other sedatives like alcohol can stop breathing.
Depends . If you are using Klonopin for seizures, the highest dose can be up to 15 or 17 mg a day! However for anxiety, I wouldn't go over 4 mg a day. Very few patients go up to 8 mg a day. Klonopin has a very long half life and may make you very tired. If you are using other medicines , than more than 2 mg of Klonopin a day should suffice. Let your doctors guide you and don't mix alcohol or other sedative .
