Klonopin Wafer and Alcohol/Food Interactions
There are 2 alcohol/food/lifestyle interactions with Klonopin Wafer (clonazepam).
Clonazepam Alcohol (Ethanol)
Moderate Drug Interaction
GENERALLY AVOID: Acute ethanol ingestion may potentiate the CNS effects of many benzodiazepines. Tolerance may develop with chronic ethanol use. The mechanism may be decreased clearance of the benzodiazepines because of CYP450 hepatic enzyme inhibition. Also, it has been suggested that the cognitive deficits induced by benzodiazepines may be increased in patients who chronically consume large amounts of alcohol.
MANAGEMENT: Patients should be advised to avoid alcohol during benzodiazepine therapy.

Clonazepam Obesity
Moderate Potential Hazard, Moderate plausibility
benzodiazepines - obesity
The plasma half-lives of benzodiazepines may be prolonged in obese patients, presumably due to increased distribution into fat. Marked increases in distribution (> 100%) have been reported for diazepam and midazolam, and moderate increases (25% to 100%) for alprazolam, lorazepam, and oxazepam. Therapy with benzodiazepines should be administered cautiously in obese patients, with careful monitoring of CNS status. Longer dosing intervals may be appropriate. When dosing by weight, loading doses should be based on actual body weight, while maintenance dose should be based on ideal body weight to avoid toxicity.
