Bupropion

Bupropion is an atypical antidepressant medication sold under the brand names include Wellbutrin, Aplenzin, and Zyban, and formerly Budeprion. In addition to treating depression and severe pain, it is also used to treat seasonal affective disorder (SAD), and to reduce cravings in smoking cessation and drug addiction.

Types
Bupropion is available in different forms, and may be combined with other drugs for particular uses, including
 * Sublingual Bupropion HCl, branded as Subutex for the treatment of drug dependency/addiction
 * Bupropion for smoking cessation, brand name Zyban
 * Bupropion for major depression, brand name Wellbutrin

Theory
Buproprion, like all antidepressants, does not address the underlying mechanisms of ME/CFS, so should not be regarded as a cure. It should be used only to reduce particular symptoms or treat a co-existing disorder (e.g. depression), and it is not a primary treatment for ME/CFS.

ME/CFS patients may tolerate brand name bupropion better than generic versions due to sensitivities.
