Interactions between your drugs

Moderate

modafinil eszopiclone

Applies to: modafinil and eszopiclone

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of zopiclone, which is a substrate of the isoenzyme. According to product labeling, zopiclone systemic exposure (AUC) was decreased 80% by concomitant use of rifampin, a potent inducer of CYP450 3A4. A similar effect would be expected with eszopiclone, the S-enantiomer of zopiclone. Pharmacodynamically, many CYP450 3A4 inducers such as barbiturates and anticonvulsants have CNS-depressant effects, which may be additive with those of zopiclone and eszopiclone.

MANAGEMENT: Pharmacologic response to zopiclone and eszopiclone should be monitored more closely whenever a CYP450 3A4 inducer is added to or withdrawn from therapy, and the hypnotic dosage adjusted if necessary.

Drug and food interactions

Moderate

eszopiclone food

Applies to: eszopiclone

Taking eszopiclone with a high-fat or heavy meal may delay the onset of sleep. For faster sleep onset, eszopiclone should not be administered with or immediately after a high-fat or heavy meal. This will make it easier for your body to absorb the medication. You should avoid the use of alcohol while being treated with eszopiclone. Alcohol can increase the nervous system side effects of eszopiclone such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. Talk to your doctor or pharmacist if you have any questions or concerns.
