Description: The Food and Drug Administration (FDA), which regulates the production and sale of prescription medicines in the United States, has not approved Frisium (clobazam). This means that if you live in the United States, you cannot get it from your drugstore in the same way that you get most other seizure medicines. (It is available in many other countries, including Canada, Australia, and the UK.) Frisium belongs to the class of medications called benzodiazepines. Ativan (lorazepam) and Tranxene (chlorazepate) are other well-known benzodiazepines that are often prescribed for treating seizures. They have been approved by the FDA for sale in the United States. Your doctor will almost certainly recommend that you try medicines like these before trying Frisium, and one or more of them are likely to work well for you.
