Interactions between your drugs

Moderate

flurazepam kava

Applies to: flurazepam and kava

GENERALLY AVOID: A case report suggests that kava may increase the central nervous system adverse effects of benzodiazepines. In the report, a 54-year-old man treated with alprazolam became semicomatose with lethargy and disorientation following self-medication with kava for 3 days. The exact mechanism of interaction is unknown, but an additive or synergistic CNS effect is suspected.

MANAGEMENT: Until further information is available, concomitant use of kava and benzodiazepines is not recommended. Patients on benzodiazepines should be advised to consult their caregiver before using any alternative medicines.

Drug and food interactions

Moderate

flurazepam food

Applies to: flurazepam

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

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.
