Mental Health Home > Side Effects of Buspirone

Headaches, nervousness, and dizziness are some of the most common side effects of buspirone. Rare side effects (occurring in less than 1 percent of people) may include chest congestion, high or low blood pressure, and acne. Certain reactions to buspirone are more serious and should be reported to a healthcare provider, such as mood changes, hallucinations, and involuntary body or facial movements.

Buspirone Side Effects: An Introduction

As with any medicine, side effects are possible with buspirone hydrochloride (BuSpar®); however, not everyone who takes the drug will experience problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with buspirone. Your healthcare provider can discuss a more complete list of buspirone side effects with you.)

  • Personality changes or mood changes
