42 year old male, how long does Buspar (buspirone) stay in your system. I have been taking 15mg a day for 3.5 weeks. 7.5 mg twice a day.?

In brief: 3-hours half-life

Buspar (buspirone hcl) has a relatively short half-life (the time it takes for 1/2 to disappear in your body) is only about 3 hours.
Typically, after 5-6 half-lives, there isn't much left in the body following the last dose. Because you r using a small dosage, there isn't much in your body after a day or 2. If you have additional concern, repost questions or consult doc. Good luck.
