Buspirone ( BuSpar ) data sheet


Buspirone (BuSpar®) is an anxiolytic (antianxiety agent), used primarily for relief of mild to moderate general anxiety disorder. Alcohol does not interact in a dangerous manner with Buspirone and Buspirone may be useful in reducing alcohol craving; it is being researched as a treatment for alcoholism.

Buspirone is unique compared to most anti-anxiety drugs. It is not a benzodiazepine or barbiturate or SSRI - it does not relax muscles or interfere with serotonin reputake. In fact, it is not really understood how Buspirone works to relieve anxiety.

Although it may taken for up to one year without adverse effects, Buspirone is shown to be most effective for short-term use.

Side Effects

Buspirone is less "drowsy" than most other anxiety medications. However, the effects vary from patient to patient and there are potential side effects, including:

Dizziness, drowsiness, headache, nausea, nervousness, lightheadedness, restlessness, blurred vision, tiredness, insomnia.

A small percentage of patients may develop movement disorders such as shakiness (tremors), muscle stiffness, mask-like facial expression, jerky walking movements, or a condition known as tardive dyskinesia. In some cases, these conditions may be permanent.

Seek immediate medical attention if any of these rare but serious side effects occur: easy bleeding/bruising, shortness of breath, chest pain, fast/irregular heartbeat.

A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
