Since the drug is also an antispasmodic, it is also prescribed to prevent seizures associated with epilepsy and relieve the symptoms of restless legs syndrome. Although this drug is known as Klonopin® in the US, it is marketed in countries including Great Britain under the trade name Rivotril® by the Swiss company F. Hoffmann-La Roche AG.

Klonopin is assigned to the drug group of benzodiazepines. It changes mood and affects the central nervous system. Biochemical effects on the brain give the drug the ability to affect cognition and behavior. Unfortunately, these properties also lead to the deliberate abuse of this substance.

Are there any risks if you buy clonazepam and take it for epilepsy?

As with other psychiatric drugs, there are certain risks associated with taking Klonopin. There is a risk of developing chemical dependency through long-term or habitual use. For this reason, the preparation should be used under medical supervision.

What interactions to consider before buying Klonopin (Clonazepam)?

Taking Clonazepam-containing Klonopin at the same time as medicines that have a central nervous system inhibitory effect, such as ethanol or medicines containing ethanol, leads to an increase in the central nervous system inhibitory effect.

In the case of a combination of clonazepam and desipramine, the plasma level of desipramine is reduced.

The effect of muscle relaxants is enhanced with simultaneous use with clonazepam. Concomitant administration with clonazepam reduces the effect of valproate.

When taken at the same time as caffeine, it is possible to reduce the sedative and anxiolytic effects of clonazepam.

When Klonopin is combined with lamotrigine, the plasma concentration of clonazepam decreases. Simultaneous administration with lithium carbonate can lead to the development of neurotoxicity.

With the simultaneous use of clomazepam with primidone, the plasma concentration of primidone increases.

The drug Klonopin also interacts with phenytoin. However, caution is advised as concomitant use increases the plasma level of phenytoin and toxic reactions and concentration disorders may occur.

Phenelzine can cause the headache when combined with Clomazepam.

With simultaneous administration with cimetidine, side effects from the central nervous system increase, but in some patients the frequency of seizures decreased.

Klonopin drug also interacts with tiapride, toremifene and many other drugs and medications. For this reason, you should inform your doctor about all the preparations you are taking or have recently taken.

I lived very well with Klonopin for 3 years, but this year I was allowed to get to know the downsides of such a powerful drug.


I started taking Klonopin 2 years ago and am not considering switching to another drug. I`m sleeping well again. When I fell asleep, I felt abrupt impulses that have now disappeared. I`ve tried coming off Klonopin before but have experienced a lot of withdrawal symptoms. So I`m taking this drug again.
