What is alprazolam?
Alprazolam is a benzodiazepine (ben-zoe-dye-AZE-eh-peen). It is thought that it works by enhancing the activity of certain neurotransmitters in the brain.
Alprazolam is used to treat anxiety disorders, panic disorders, and anxiety caused by depression.
It is dangerous to purchase alprazolam on the Internet or outside the United States. The sale and distribution of medicines outside the U.S. does not comply with safe-use regulations of the Food and Drug Administration (FDA). These medications may contain dangerous ingredients, or may not be distributed by a licensed pharmacy.
