Klonopin is a prescription medication that contains clonazepam, which is a type of benzodiazepine. It's commonly used to help manage panic disorders, anxiety, and certain kinds of seizures. The way it works is by calming down the brain's overactive activity, which can help ease feelings of nervousness, prevent panic attacks, and control seizure episodes. It's really important to use Klonopin under the supervision of a healthcare provider, as using it for a long time can lead to dependence.
