Interactions between your drugs

Moderate

zolpidem viloxazine

Applies to: Ambien CR (zolpidem) and viloxazine

MONITOR: Coadministration with viloxazine, a potent CYP450 1A2 inhibitor may increase the plasma concentrations of CYP450 1A2 substrates leading to increased toxicity. According to the prescribing information, viloxazine increased the systemic exposure (AUC) of caffeine, a probe CYP450 1A2 substrate, by nearly 6-fold without affecting its peak plasma concentration (Cmax).

MANAGEMENT: Monitor for toxicities of CYP450 1A2 substrates whenever viloxazine is added to or withdrawn from therapy. Adjust doses of CYP450 1A2 substrates as clinically indicated.

Drug and food interactions

Moderate

zolpidem food

Applies to: Ambien CR (zolpidem)

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

ADJUST DOSING INTERVAL: Administration of zolpidem with food may delay the onset of hypnotic effects. In 30 healthy subjects, administration of zolpidem 20 minutes after a meal resulted in decreased mean peak plasma drug concentration (Cmax) and area under the concentration-time curve (AUC) by 25% and 15%, respectively, compared to fasting. The time to reach peak plasma drug concentration (Tmax) was prolonged by 60%, from 1.4 to 2.2 hours.

MANAGEMENT: Patients receiving zolpidem should be advised to avoid the consumption of alcohol. For faster sleep onset, zolpidem should not be administered with or immediately after a meal.

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.
