Zopiclone is a drug that is often prescribed to treat insomnia, but like most medications, it comes along with some bothersome side effects. Some of the most common zopiclone side effects that should be reported to a doctor include anxiety, mood swings, and confusion, though some people experience sudden aggressiveness or difficulty breathing, as well. There are also some side effects that do not typically need to be reported to a doctor since they are not dangerous to the health and should subside in time, including dry mouth, changes to appetite and weight, and dizziness. Finally, some side effects may last even after the medication is discontinued, such as cramps, nausea, excessive sweating, and increased insomnia.

Certain side effects from zopiclone should be reported to a doctor since they may be harmful. For example, confusion, drowsiness, clumsiness, and decreased coordination should be mentioned to a doctor since these negative effects can be dangerous, particularly when operating a vehicle. Mood swings, anxiety, aggressiveness, and a skin rash may also occur, and though not usually dangerous to the health of the patient, they can be detrimental to the quality of life. Symptoms like wheezing, chest tightness, and difficulty breathing can also be scary, which is why patients should contact their doctor right away if they experience these side effects.


On the other hand, some of the side effects are not life-threatening, which means that they do not typically need medical attention unless they are particularly bothersome to the patient. In fact, many of them subside as the body gets used to the drug, so some patients can expect to observe side effects like dry mouth, heartburn, appetite changes, and weight loss. It may also become difficult to see clearly or speak at times, and some patients taking this drug may notice themselves becoming easily agitated. Finally, other physical symptoms that should subside soon may include chills, constipation, dizziness, and vomiting. If the side effects continue after regular use of the medication, or become hard to ignore, patients should typically notify their doctor.

While some zopiclone side effects are not particularly dangerous or long-lasting, others last even after use of the drug has been stopped. For instance, stomach cramping, vomiting, and nausea may continue after the drug is no longer used. Insomnia that is worse than before may also appear, perhaps partly due to the anxiety, excessive sweating, and general restlessness that may begin once the drug is stopped. It is usually advised that patients inform their doctor once they notice these negative effects.

I've actually not read of many people complaining about zopiclone side effects. But I've read people complaining about addiction and withdrawal symptoms. That seems to be more of an issue.

@donasmrs-- I used zopiclone for a brief time but then quit because of the anxiety. I didn't use it long enough to know whether it goes away or not. The anxiety was very severe for me and I had other side effects too. I also had headaches, and issues with memory. I just felt bad overall, I did not have a pleasant experience with this drug at all.

You ought to speak to your doctor about this. And if the side effects worsen, ask your doctor about quitting zopiclone safely and ask about trying a different drug. There are other alternatives out there. I don't think that anyone should be forced to take something if it causes many, severe side effects.

My doctor put me on zopiclone for sleep problems. The drug seems to be working, but it has side effects. The most pronounced side effect I'm experiencing is anxiety.

Is anyone else her on zopiclone? Do you have anxiety from it too? Is this something that will go away with time?
