Interactions between your drugs

Moderate

clonazePAM fospropofol

Applies to: clonazepam and fospropofol

MONITOR: Additive central nervous system and cardiorespiratory depressant effects may occur when fospropofol or propofol is administered with other depressants such as sedative-hypnotic agents and narcotic analgesics.

MANAGEMENT: Patients should be monitored closely for excessive sedation and cardiorespiratory depression, and the medication dosage(s) adjusted accordingly. Supportive therapy should be provided if needed.

Drug and food interactions

Moderate

clonazePAM food

Applies to: clonazepam

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
