Question about Wellbutrin SR/XL (Bupropion SR/XL)...?
Question:
bupropion (Wellbutrin)
bupropion ext-release (Wellbutrin SR)
bupropion ext-release 300 mg (Wellbutrin XL)
Does that mean that the generic form of Wellbutrin SR is the same as the generic form of Wellbutrin XL, just that XL is bupropion extended release at 300 mg??
Answers:
Yes they are pretty much the same, the SR is sustained release, and some people take it twice a day, the XL at 300mg, only has to be taken once a day, it releases even slower into your system.
SR is extended release. There are several different strengths, and 300mg is the largest and newest. I think the XL stands for extra large or something, I don't know, but it is extended release also (The full product name is Bupropion HCl ER [extended release] XL Tabs, 300mg). I should know, I work as a chemist at a company that makes generic bupropion and I test it all the time!
It's like the last person said, SR is sustained release and has to be taken twice a day, while XL is extended release and is only taken once a day. The thing about the XL is that only the 300mg pills have gone generic. The 150mg pills have not, yet.
