What does it do?

Zopiclone is used to help you sleep.

How should you take it?

  • some antihistamines (may be in anti-allergy, anti-nausea and cough/cold medicines)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort, valerian) or recreational drugs.
