Clonazepam: Uses, Side Effects, Anxiety, Panic Attacks, Dependence and Safety
Clonazepam is a prescription medicine belonging to a group of medicines called benzodiazepines. It is used to control certain seizure disorders and to treat panic disorder. In the United States, clonazepam is a controlled substance and is available only by prescription.
It can be helpful when appropriately prescribed, but it also comes with important warnings about drowsiness, dependence, withdrawal and interactions with other medicines or substances.
What is clonazepam used for?
Clonazepam is primarily used for:
Certain types of seizures
Panic disorder and recurrent panic attacks
It works by reducing abnormal activity in the brain and producing a calming effect on the nervous system.
Although people sometimes search for clonazepam for general anxiety or sleep problems, that does not mean it is appropriate for everyone experiencing anxiety or insomnia.
How does clonazepam work?
Clonazepam increases the effects of GABA, a chemical messenger that helps slow activity in the brain.
This can produce a calming and sedating effect. That is part of why clonazepam may reduce panic symptoms, but it is also why some people experience sleepiness, dizziness, poor coordination or difficulty concentrating.
Does clonazepam make you sleepy?
Yes. Drowsiness is one of the common side effects of clonazepam.
Some people may also experience:
Dizziness
Unsteadiness
Poor coordination
Slower thinking
Memory problems
Do not drive or operate machinery until you know how clonazepam affects you.
Using clonazepam simply as a sleeping pill is not something to do without medical guidance.
Clonazepam for anxiety and panic attacks
Clonazepam is approved for panic disorder, where a person experiences recurrent unexpected panic attacks.
A panic attack can involve intense fear or discomfort along with symptoms such as a racing heartbeat, shaking, sweating, shortness of breath or a feeling that something terrible is about to happen.
Clonazepam may reduce the intensity of panic symptoms, but long-term treatment decisions should consider the risks of benzodiazepine dependence and other available approaches.
Common clonazepam side effects
Possible side effects include:
Drowsiness
Dizziness
Unsteadiness
Coordination problems
Difficulty thinking clearly
Memory problems
Not everyone experiences these effects, and some may become less noticeable as the body adjusts to the medicine.
If symptoms are severe or interfere with daily activities, speak with your healthcare professional.
Can clonazepam cause dependence?
Yes.
This is one of the most important things to understand about clonazepam.
The FDA requires a boxed warning for benzodiazepines because they can cause abuse, misuse, addiction, physical dependence and withdrawal reactions. These risks can occur even when the medicine is used as prescribed.
Physical dependence and addiction are not exactly the same thing.
A person can become physically dependent on clonazepam without having an addiction. Dependence means the body has adapted to the medicine and may react when it is suddenly reduced or stopped.
Can you stop clonazepam suddenly?
It is important not to stop clonazepam suddenly without medical advice if you have been taking it regularly.
Rapid reduction or abrupt discontinuation can cause withdrawal symptoms, and in some cases withdrawal can include seizures or other serious complications.
A healthcare professional can determine whether the medicine should be reduced gradually and what approach is appropriate for the individual.
There is no single tapering schedule that is suitable for everyone.
Clonazepam withdrawal symptoms
Withdrawal can vary considerably from person to person.
Possible symptoms include:
Anxiety or panic
Sleep problems
Irritability
Shaking
Difficulty concentrating
Memory problems
Muscle twitching
Changes in mood
Seizures in serious cases
The FDA specifically warns that benzodiazepine withdrawal can sometimes be severe or life-threatening.
If someone taking clonazepam regularly wants to discontinue treatment, medical supervision is the safer approach.
Clonazepam and alcohol
Combining clonazepam with alcohol can increase sedation and other dangerous effects.
Alcohol can make the side effects of clonazepam worse, and the FDA warns about the risks of combining benzodiazepines with substances that depress the central nervous system.
For safety, discuss alcohol use with your healthcare professional rather than assuming that the combination is harmless.
Clonazepam and opioids
This combination deserves particular attention.
Taking clonazepam together with opioid medicines can increase the risk of profound sedation, respiratory depression, coma and death.
This is especially relevant for people who take opioid pain medicines such as tramadol or tapentadol.
If you take clonazepam and an opioid, your healthcare professional needs to know about both medicines.
Does clonazepam make you feel “high”?
Clonazepam can cause sedation and changes in alertness, but using it to produce a “high” is misuse.
Taking more than prescribed or combining it with alcohol, opioids or other sedating substances can substantially increase the risk of dangerous effects.
Never increase the amount because the prescribed dose no longer seems to have the same effect.
Clonazepam and sleep
Because clonazepam can cause drowsiness, some people may feel that it helps them sleep.
That does not necessarily make it an appropriate long-term treatment for insomnia.
If sleep problems continue, the underlying reason for the insomnia should be evaluated rather than simply relying on a sedating medicine.
Who should be especially careful with clonazepam?
Tell your healthcare professional if you have:
Lung or breathing problems
Liver disease
Kidney disease
Glaucoma
A history of substance misuse
A history of depression or other mental health conditions
Pregnancy or plans to become pregnant
Older adults may also be more sensitive to the sedating and coordination-related effects of benzodiazepines.
What happens if you take too much clonazepam?
An excessive amount can cause significant drowsiness, confusion and loss of consciousness.
The risk becomes more serious when clonazepam is combined with alcohol, opioids or other central nervous system depressants.
If someone is extremely difficult to wake, has slowed or difficult breathing, collapses, or becomes unresponsive, seek emergency medical assistance immediately.
Frequently asked questions about clonazepam
What is clonazepam mainly used for?
Clonazepam is used to control certain seizures and to treat panic disorder.
Does clonazepam make you sleepy?
Yes. Drowsiness is a common side effect, along with dizziness and problems with coordination.
Is clonazepam addictive?
Clonazepam can cause abuse, misuse, addiction and physical dependence. The FDA has a boxed warning covering these risks for benzodiazepines.
Can clonazepam be used for anxiety?
Clonazepam is approved for panic disorder. Whether it is appropriate for another type of anxiety depends on the individual situation and should be determined by a healthcare professional.
Can clonazepam and alcohol be taken together?
The combination can increase sedation and other serious risks. Discuss alcohol use with your healthcare professional.
Can clonazepam be stopped suddenly?
Regular clonazepam use should not generally be stopped abruptly without medical guidance because withdrawal can be serious, including potentially life-threatening seizures.
Can clonazepam be taken with tramadol?
Both medicines can depress the central nervous system, and combining a benzodiazepine with an opioid can increase the risk of severe sedation and respiratory depression. This combination should only be used when specifically managed by a healthcare professional.
The bottom line
Clonazepam can play an important role in treating panic disorder and certain seizure conditions, but it is not a medicine to take casually.
Its calming effects can also cause drowsiness, impaired coordination and memory problems. More importantly, regular use can lead to physical dependence, and suddenly stopping the medicine can cause serious withdrawal.
The safest approach is to use clonazepam exactly as prescribed, avoid combining it with alcohol or other sedating substances unless specifically advised, and speak with a healthcare professional before changing or stopping treatment.
