Head-to-head comparisons of medication uses, side effects, warnings, and more.
Clonazepam (Klonopin) and lorazepam (Ativan) are both benzodiazepines, but they have some key differences. Clonazepam is used to treat seizures in both adults and children, and panic disorder in adults. It's taken by mouth two to three times a day and is available as a generic. Lorazepam is mainly used for short-term treatment of anxiety and is also available as a generic. It's taken by mouth one to three times a day or given as an injection by healthcare professionals to control seizures or ease anxiety before surgery. Both medications are not recommended for long-term use due to the risk of dependence and other side effects. Additionally, both medications can cause drowsiness and dizziness, and you should avoid alcohol while taking them. Lorazepam might start working faster, within 30 minutes, compared to clonazepam, which takes a few hours to reach its highest level in the body.
