Are they prescribed for different medical conditions? Do the pills contain different chemicals? Which of them causes the least side effects?

Wellbutrin - immediate release pills taken three times daily for the treatment of major depressive disorder.
Wellbutrin SR - sustained-release pills taken twice daily for the treatment of major depressive disorder.
Wellbutrin XL - extended-release pills taken once daily for the treatment of major depressive disorder and seasonal affective disorder.
All Wellbutrin formulations contain the same active ingredient, bupropion.
Sorry I couldn't find any information comparing the side effect profiles for each of the types of Wellbutrin. In general the longer acting medicines have fewer side effects because the blood levels of the drug remain steadier.

You should also note that there can be come confusion between the SR and XL generics, so be certain to double check with your pharmacist that you have the right one (once a day or twice a day) when you fill it for the first time or change generics.

Both products contain the same active ingredient bupropion. Wellbutrin SR (Sustained Released) is formulated to release slowly from the tablet and is taken twice daily. Wellbutrin XL (Extended Release) has a slower release over 24 hours and is taken once daily.
