Interactions between your drugs

Moderate

clonazePAM trofinetide

Applies to: clonazepam and trofinetide

MONITOR: Coadministration with trofinetide may increase the plasma concentrations of drugs that are substrates of CYP450 3A4 via inhibition of the isoenzyme. Based on pharmacokinetic modeling, concomitant use of trofinetide and oral midazolam, a sensitive CYP450 3A4 substrate, is predicted to increase midazolam systemic exposure (AUC) by approximately 1.33-fold. Clinical data are currently lacking.

MANAGEMENT: Caution is advised if trofinetide is coadministered with CYP450 3A4 substrates, particularly sensitive substrates or those with a narrow therapeutic range. If concomitant use is required, clinical and laboratory monitoring may be appropriate whenever trofinetide is added to or withdrawn from therapy. The prescribing information for concomitant medications should be consulted to assess the benefits versus risks of coadministration and for any dosage adjustments that may be required.

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.
