Restyl

What is  Restyl (alprazolam)?

Alprazolam belongs to a group of drugs called benzodiazepines (ben-zoe-dye-AZE-eh-peens). It works by slowing down the movement of chemicals in the brain that may become unbalanced. This results in a reduction in nervous tension (anxiety).

Alprazolam is used to treat anxiety disorders, panic disorders, and anxiety caused by depression.

Alprazolam may also be used for purposes not listed in this medication guide.

How should I take alprazolam?

Take alprazolam exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results.

Do not crush, chew, or break an extended-release tablet. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking the pill would cause too much of the drug to be released at one time.

Measure the liquid form of alprazolam with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

Do not swallow the orally disintegrating tablets whole. Allow it to dissolve in your mouth without chewing.

Contact your doctor if this medicine seems to stop working as well in treating your panic or anxiety symptoms.

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?
