Wellbutrin SR: Common Uses, Dosage, Side Effects and Precautions

What is Wellbutrin and Wellbutrin SR?

Wellbutrin is a prescription drug that is used to treat people with a major depressive disorder. This antidepressant medication may also be used to help people quit smoking. It contains an active ingredient known as Bupropion, which increases certain chemicals in your brain that gives you the pleasurable feelings. Scientists do not know how exactly Wellbutrin works in treating depression but it is presumed it inhibits the reuptake of dopamine and norepinephrine.
