Buspar Side Effects Associated with Discontinuation of Treatment

One guide to the relative clinical importance of adverse events associated with buspirone HCl is provided by the frequency with which they caused drug discontinuation during clinical testing. Approximately 10% of the 2200 anxious patients who participated in the buspirone HCl premarketing clinical efficacy trials in anxiety disorders lasting 3 to 4 weeks discontinued treatment due to an adverse event.

The more common events causing discontinuation included:

• central nervous system disturbances (3.4%): primarily dizziness, insomnia, nervousness, drowsiness, and lightheaded feeling;
• gastrointestinal disturbances (1.2%), primarily nausea;
• miscellaneous disturbances (1.1%), primarily headache and fatigue.

In addition, 3.4% of patients had multiple complaints, none of which could be characterized as primary.
