What Are the Signs of a Zopiclone Overdose?

By Meshell Powell
Updated: Mar 03, 2024

Signs of a zopiclone overdose may vary widely depending on the amount of medication taken as well as whether alcohol or other drugs were also consumed. Extreme drowsiness, lethargy, and loss of muscle control are among the most common symptoms of an overdose of zopiclone. Paleness, blurred vision, and excessive sweating may also occur if too much of this medication has been taken. In the most severe cases, breathing problems, loss of consciousness, or death are possible. Anyone who is thought to have taken a zopiclone overdose should be transported to the nearest hospital for emergency medical care.

One of the first signs of a overdose of zopiclone is often a feeling of severe drowsiness. The affected person may become so sleepy that normally simple tasks, such as walking or carrying on a coherent conversation, become difficult or impossible. Lethargy, or a feeling of weakness, may become so strong that the body feels too heavy to move, sometimes causing the person to crawl instead of attempting to walk.

Ataxia, or an inability to properly control muscle movements, is a common sign of a zopiclone overdose. A person who has consumed a toxic amount of this medication may seem to stagger and speech may be slurred. Many people have described these symptoms as being similar to those experienced when someone has consumed large quantities of alcohol. Tremors or uncontrollable limb movement may sometimes occur as a result of an overdose.

Sudden or profuse sweating and pale or clammy skin may result from a zopiclone overdose, and body temperature fluctuations may also occur. Vision may become blurry and the affected person may have trouble focusing or concentrating. Mood changes and hallucinations have been known to occur when large amounts of this drug have been ingested. If the overdose patient begins to exhibit aggressive or destructive behavior, the local police department should be contacted for help in transporting the person to the nearest hospital.

The muscles that control respiration may slow down considerably due to a zopiclone overdose and can cause breathing to become difficult. Heart function may also be affected, leading to irregular heartbeat or a sudden drop in blood pressure. When this occurs, a loss of consciousness is possible, sometimes leading to coma. Without immediate medical attention, a zopiclone overdose can prove to be fatal. Emergency services should be contacted any time that an overdose is suspected so that life support measures can begin before the patient reaches the hospital.

Is 360 mg of this drug bad? What might happen?

Are migraines and bad memory signs of zopiclone overdose? I've been experiencing both for the past few days. I'm worried.

Pressure ulcers are also a sign of zopiclone overdose. If muscle movement slows down or stops because of the medication, the pressure created from sitting or lying in the same position for a long time can lead to pressure ulcers. They're very painful and are not pretty to look at.

One would think that if there is loss of muscle movement, the person would know. But some people abuse zopiclone for its hallucinogenic effects and might not be aware that they are losing mobility in the process.

I work in the emergency room and I have seen quite a few cases of zopiclone overdose. Thankfully, most of them were not serious and we were able to keep the patients under observation for several hours and send them home.

However, a few of the cases were serious and the patients went into respiratory or cardiac arrest. This medication is very dangerous when overdosed. The article mentioned all of the signs. I hope people can be more careful when using this medication.
