What is Klonopin?

Klonopin is the brand name of generic medication, Clonazepam, and it comes in tablet form. It is a habit-forming and life-threatening benzodiazepine, which is a broad group of central nervous system depressants. Clonazepam is sold under the brand name Klonopin. When it is prescribed by a doctor, Klonopin helps calm abnormally active electrical signals in the brain. When the brain is overactive, it may cause anxiety, muscle spasms, a sleeping disorder, seizure or other nervous system disorders. Klonopin is mostly used to treat seizures in people with neurological disorders such as epilepsy. It’s an intermediate-acting benzodiazepine that can diminish the risk of seizure activity for several hours after taking the medication. Mental health specialists every so often recommend Klonopin to help prevent panic attacks or episodes of extreme anxiety. It’s additionally prescribed to psychiatric patients who are experiencing anxiety, fidgeting or other uncontrollable movements as a result of taking antipsychotic prescriptions. Klonopin ordinarily isn’t recommended for the short-term treatment of insomnia or anxiety. Drugs such as Xanax and Ativan are much more effective for the treatment of these disorders since they start working within minutes and their effects don’t last as long as Klonopin.

Many people who are wondered how long Klonopin will stay in their system. To determine how long it will stay in your system after your last dose, it’s important to consider the half-life of Klonopin’s active ingredient, Clonazepam. Clonazepam has a long elimination half-life. Half-life denotes to how long it takes for half of a single dose of a drug to leave the body. For Clonazepam, it’s elimination half-life which ranges from 30 to 40 hours. This implies that it will take between 1-2 days for only half of Klonopin to leave your system. Based on the estimate of Clonazepam’s 30 to 40-hour half-life, Klonopin is to be expected to stay in your system for roughly 6-9 days after your last dose. It’s worth noting, however, that some health experts recommend that Clonazepam has a wider-ranging half-life of 18 to 60 hours. If so, it can take anywhere from 4-14 days to completely leave your system. As Clonazepam is absorbed in the liver, it forms the metabolite known as “7-aminoclonazepam.” Most health experts believe that the half-life of 7-aminoclonazepam is either shorter or like that of clonazepam. Therefore, your body should clear Klonopin and its metabolite within two weeks of stopping use.
