Wellbutrin XL Side Effects

Although most people have no problems when taking Wellbutrin XL, side effects are possible, such as headaches, dry mouth, and weight loss.

However, some side effects should be reported immediately to your healthcare provider, including suicidal thoughts or behavior, seizures, and hallucinations.
