A medication that is frequently prescribed to treat insomnia is zopiclone. It is a member of the sedative-hypnotic prescription subclass. The normal Zopiclone dosage is 7.5 mg, though this can change based on the needs of the patient and the prescription doctor's recommendations. Unsurprisingly, zopiclone itself is the active component of Zopiclone. Each pill or capsule of medication contains 7.5 mg of zopiclone, which is the dosage.
