What is the most important information I should know about clonazepam (Klonopin)?

Do not use this medication if you have severe liver disease, of if you are allergic to clonazepam or to other benzodiazepines, such as alprazolam (Xanax), chlordiazepoxide (Librium), clorazepate (Tranxene), diazepam (Valium), lorazepam (Ativan), or oxazepam (Serax).

Clonazepam may cause harm to an unborn baby, and may cause breathing or feeding problems in a newborn. But having a seizure during pregnancy could harm both the mother and the baby. Do not start taking clonazepam during pregnancy without telling your doctor you are pregnant.

If you become pregnant while taking clonazepam for seizures, do not stop taking clonazepam without your doctor's advice. Seizure control is very important during pregnancy and the benefits of preventing seizures may outweigh any risks posed by taking clonazepam.

Do not drink alcohol while taking clonazepam. This medication can increase the effects of alcohol.

Clonazepam may be habit-forming and should be used only by the person it was prescribed for. Clonazepam should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.
