Buspirone Overview

How it works

Buspirone is in a class of medications called anxiolytics. It is used to treat anxiety disorders. Buspirone works by changing the amounts of certain natural substances in the brain that help maintain mental balance.


Buspirone is a non-controlled medication, which means that it is not classified as having euphoric or addictive properties. There are no cravings, no hazardous behaviors, and no examples of prolonged addictive behavior associated with it.

Buspirone may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you. Remember that alcohol can add to the drowsiness caused by this medication. Do not drink alcohol while taking buspirone.

How it should be used

It may take 2 to 4 weeks or longer before you feel the full benefit of buspirone. Continue to take buspirone even if you feel well. 

Do not stop taking buspirone without talking to your doctor. Your doctor will probably decrease your dose gradually.

What to do if you forget a dose

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
