Use the lowest effective dose for the patient.
2.1 Dosage in AdultsThe recommended starting dose is 1 mg. Dosing can be raised to 2 mg or 3 mg if clinically indicated. In some patients, the higher morning blood levels of eszopiclone tablets following use of the 2 mg or 3 mg dose increase the risk of next day impairment of driving and other activities that require full alertness [ see Warnings and Precautions ( 5.1) ]. The total dose of eszopiclone tablets should not exceed 3 mg, once daily immediately before bedtime [ see Warnings and Precautions ( 5.6) ].
2.2 Geriatric or Debilitated PatientsThe total dose of eszopiclone tablets should not exceed 2 mg in elderly or debilitated patients.
2.3 Patients with Severe Hepatic Impairment, or Taking Potent CYP3A4 InhibitorsIn patients with severe hepatic impairment, or in patients coadministered eszopiclone tablets with potent CYP3A4 inhibitors, the total dose of eszopiclone tablets should not exceed 2 mg [ see Warning and Precautions ( 5.7) ].
2.4 Use with CNS DepressantsDosage adjustments may be necessary when eszopiclone tablets is combined with other CNS depressant drugs because of the potentially additive effects [see Warnings and Precautions ( 5.1)].
2.5 Administration with FoodTaking eszopiclone tablets with or immediately after a heavy, high-fat meal results in slower absorption and would be expected to reduce the effect of eszopiclone tablets on sleep latency [see Clinical Pharmacology ( 12.3)] .
