I'm on Buspirone and YES, you do need to wean off. Talk to your doctor before you do this. I'm surprised at your age they are giving you this medication. Especially because of your age, talk to your doctor first, as there can be serious peradoxil effects if you don't wean properly. As well, give the medication a little bit longer to see the full effects before deciding not to take it. I'm not sure of your reasons for taking it, so to say you should/shouldn't take it isn't up to me or anyone in this forum. Good luck!
I took Buspirone together with Paxil for a long time. I'm certainly not a doctor but when I stopped taking them both, the Paxil I had to wean off of because it's an SSRI but the Buspirone I just stopped and didn't have any problems. BUT, I would definitely consult with your doctor first to see what he/she recommends because everyone is different and certain medications you cannot just stop cold turkey. Good luck!! I put some sites below regarding the medication...hope it helps.
