Warnings for people with certain health conditions

For people with history of liver problems: This drug is broken down by your liver. If you have liver problems, you may not be able to break down this drug well. It may build up in your body and cause more side effects. These include trouble thinking or concentrating, drowsiness, and problems with coordination. Your doctor may give you a lower dose of this drug.

For people with mental health issues, such as depression: If you have a history of depression, you may be at an increased risk of suicidal thoughts (thoughts of harming yourself) while taking this drug. Your doctor should give you a lower dose of this drug.

Warnings for other groups

For pregnant women: Eszopiclone is a category C pregnancy drug. That means two things:

  1. Research in animals has shown adverse effects to the fetus when the mother takes the drug.
  2. There haven’t been enough studies done in humans to be certain how the drug might affect the fetus.

Talk to your doctor if you’re pregnant or planning to become pregnant. This drug should only be used if the potential benefit justifies the potential risk to the fetus.

Call your doctor if you become pregnant while taking this drug.

For women who are breastfeeding: It isn’t known if eszopiclone passes into breast milk. If it does, it may cause side effects in a child who is breastfed.

Talk to your doctor if you breastfeed your child. You may need to decide whether to stop breastfeeding or stop taking this medication.

For seniors: The kidneys of older adults may not work as well as they used to. This can cause your body to process drugs more slowly. As a result, more of a drug stays in your body for a longer time. This raises your risk of side effects.

When to call the doctor
Call your doctor if you still have trouble sleeping after taking this drug for 7 to 10 days.

If you’re over the age of 65 years, you have an increased risk of mental and motor side effects from this drug. These include trouble thinking or concentrating, drowsiness, and problems with coordination. Seniors should not take more than 2 mg per dose.
