Generic ProSom

All of the patents for ProSom have expired and there are generic versions of the medication available at this time. In fact, brand-name ProSom is no longer manufactured, so only generic ProSom is available for sale. It is available in two strengths: estazolam 1 mg and estazolam 2 mg. Par Pharmaceuticals, Teva Pharmaceuticals, and Watson Pharmaceuticals currently manufacture generic ProSom.

 

Generic ProSom: An Overview

ProSom® (estazolam) is a prescription sleep medication used for the short-term treatment of insomnia. It is part of a group of medications known as benzodiazepines.
 
ProSom was originally made by Abbott Pharmaceuticals. However, the patents for the drug have expired, and generic ProSom is available. In fact, Abbott Pharmaceuticals has chosen to stop making brand-name ProSom, so only the generic version is available for sale.

What Happened to Brand-Name ProSom?

In May 2007, Abbott Pharmaceuticals announced that it would stop making ProSom. The decision to stop making the drug was likely a financial one. Sometimes, when a medication's patents expire and generic versions become available, it is no longer profitable to make the brand-name medication. Most people choose to take a generic medication if one is available, as these are less expensive (and sometimes required by many insurance companies).
 
Even though no ProSom has been manufactured since May 2007, you may still be able to obtain it at your pharmacy until the supplies of ProSom in pharmacies and wholesalers are exhausted.
