What Is a Fatal Dose of Klonopin?

The maximum daily dose of Klonopin prescribed to an adult for any condition is 20 milligrams, notes Drugs.com. Any amount in excess of 20 milligrams in a day is an overdose and can be fatal, especially if a person is on any other drug.

Mixing other drugs with Klonopin increases the risk of fatality, states Drugs.com. Drinking alcohol while taking Klonopin increases the effects of alcohol consumption on the body. Klonopin overdoses are rarely the singular cause of fatalities, but according to research in 2011, the mixing of Klonopin with other drugs has caused thousands of deaths in recent years, states CCHR International.
