Clonazepam is an anti-anxiety medication in the benzodiazepine family, the same family that includes diazepam , alprazolam , lorazepam , flurazepam (Dalmane), and others. Understanding the precautions and warnings with clonazepam prior to taking the medication can help to ensure a safe treatment process. These precautions include being aware of potential drug interactions, possible side effects, and the risks of suddenly stopping the drug.

Valium (diazepam) is effective for occasional or short-term use for anxiety and muscle spasm. Compared to similar drugs, Valium (diazepam) acts very quickly but can have interactions with other medicines. Loricass~ My dr recently ordered xanax for me. I am currently on 2mg of Klonopin at night. He told me when I start the xanax to stop the klonopin and he told me the same thing when he put me on Valium.
