Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Alcohol and other medications that cause drowsiness: People taking this medication should not combine it with alcohol and avoid combining it with other medications, such as narcotic pain relievers or other sedatives that cause drowsiness. Doing so can cause additional drowsiness and reduced breathing as well as other side effects, which can be dangerous and possibly life-threatening.
Anxiety or restlessness: An increase in daytime anxiety or restlessness has been observed during treatment with zopiclone.
Bad taste in mouth: Zopiclone may cause you to have a coated tongue, bad breath, or a bitter taste in your mouth. These effects often occur when this medication is being used.
Behaviour changes: This medication may worsen symptoms of depression, including thoughts of suicide or wanting to harm others. It may also cause agitated or aggressive behaviour. If you experience these symptoms or any other behaviour change while taking this medication, contact your doctor immediately.
Family members or caregivers of people who are taking this medication should contact the person's doctor immediately if they notice unusual behaviour changes.
Breathing: Sedatives can suppress breathing. If you have asthma, or other lung disease that increases your risk for breathing difficulties, such as sleep apnea, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Confusion: This medication affects mental efficiency (e.g., concentration, attention, and vigilance). The risk of confusion is greater for seniors and those with brain damage.
Dependence: Dependence and abuse have occurred with the use of zopiclone. The risk of developing dependence increases with higher doses and the longer that zopiclone is used. People with a history of past or current substance use problems may be at greater risk of developing abuse or addiction while taking this medication. If this medication is stopped suddenly, you may experience withdrawal symptoms such as anxiety, agitation, diarrhea, and hallucinations. If you have been taking this medication for a while, it should be stopped gradually as directed by your doctor.
Depression: Sedative medications have been known to cause mood swings and symptoms of depression. If you have depression or a history of depression or suicidal thoughts, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication contact your doctor as soon as possible.
Drowsiness/reduced alertness: Zopiclone can cause excessive drowsiness and decreased mental alertness. Do not operate heavy machinery or drive after taking this medication. Wait at least 12 hours after taking this medication before driving or engaging in other activities that require mental alertness.
Falls and fractures: Zopiclone can cause unsteadiness and weakness, leading to falls and injuries. This is more likely to occur with older adults or people taking other medications that can cause dizziness or drowsiness.
Kidney function: Kidney disease or reduced kidney function may cause this medication to build up in the body, causing side effects. If you have kidney problems, you may require lower doses of this medication.
Lactose: Some formulations of this medication contain lactose. If you have hereditary problems of galactose intolerance, lactase deficiency, or glucose-galactose malabsorption, talk to your doctor about whether this medication is appropriate for you.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, you may require lower doses of this medication.
Memory disturbance: Amnesia of varying severity has been reported following normal doses of medications like zopiclone. This effect is rare with zopiclone.
Performing activities while not fully awake: People taking zopiclone may perform activities such as sleepwalking, driving, preparing and eating food, and making phone calls while not fully awake and unaware of their actions. The next morning, they may not remember what happened. This may be more likely to occur if you also use alcohol or other sedative medications. If you discover this has happened to you, contact your doctor immediately.
Withdrawal: Zopiclone can become habit-forming. Withdrawal symptoms similar to those occurring with related substances, including alcohol, have been observed after stopping the medication suddenly (after having taken it regularly over a period of time). These symptoms include:
- abdominal cramps
- agitation
- confusion
- diarrhea
- extreme anxiety
- headache
- irritability
- memory impairment
- muscle pain
- nervousness
- restlessness
- sleep problems such as rebound insomnia
- tension
- tremors
- vomiting
Pregnancy: The safety of using this medication during pregnancy has not been established. Zopiclone may cause harm to the developing baby if it is taken during pregnancy. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are breast-feeding and taking zopiclone, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of zopiclone have not been established for use by children and adolescents under 18 years old.
Seniors: People over 65 years old are more likely to experience dose-related side effects of zopiclone, such as drowsiness, dizziness, or impaired coordination. Lower doses should be used. Using doses that are too high may result in accidents such as falls. Talk to your doctor if you are a senior and are experiencing any of the above side effects.
