Clonazepam at a Glance

Clonazepam is a prescription drug used to treat symptoms of anxiety, seizures, and panic disorders. It works by creating a calming effect in the brain through a chemical called GABA. This muscle relaxant can help in the short term but may increase the risk of serious side effects if used too long.

Common side effects of clonazepam include drowsiness, dizziness, and coordination problems. Other potential side effects include headaches, confusion, and blurred vision. Some people experience mood changes or shortness of breath. High doses or long-term use may lead to memory issues and dependence.

Clonazepam can lead to addiction, so you should not stop taking it suddenly. Doing so can cause withdrawal symptoms such as nausea, insomnia, tremors, and seizures. In some cases, symptoms may last for weeks or months. These are signs and symptoms of post-acute withdrawal.

Medical supervision is important when reducing the dose. A doctor or pharmacist may suggest a treatment option like an outpatient program or cognitive behavioral therapy (CBT).

People with a substance use disorder or who are physically dependent on prescription medications should talk to a health care provider. They can prescribe clonazepam safely and explain the risk of dependence and how to reduce it with care.
