Bupropion Vs. Xanax: Drug Comparison

Bupropion is the active ingredient in the brand-name medication Wellbutrin SR^®. The information below is about brand name Wellbutrin SR. According to the FDA, “Generic medicines use the same active ingredients as brand-name medicines and work the same way, so they have the same risks and benefits as the brand-name medicines.”

Wellbutrin SR (bupropion sustained-release) is an antidepressant that works by inhibiting the reuptake of norepinephrine and dopamine in the brain, which helps improve mood and reduce symptoms of depression. Its FDA-approved indication includes the treatment of major depressive disorder (MDD). Off-label uses may include smoking cessation, anxiety, and attention-deficit hyperactivity disorder (ADHD). Wellbutrin SR is available in sustained-release tablet form, typically taken once or twice daily. Common side effects include insomnia, dry mouth, constipation, and headache, and it has a boxed warning for an increased risk of suicidal thoughts and behaviors in children, adolescents, and young adults during the initial stages of treatment.

Xanax^® (alprazolam) is a benzodiazepine medication used to treat anxiety and panic disorders by enhancing the activity of GABA, a neurotransmitter that calms the nervous system. Its FDA-approved indications include the treatment of generalized anxiety disorder (GAD) and panic disorder with or without agoraphobia. Xanax is available in tablet, extended-release tablet, and oral solution forms, typically taken once to multiple times daily depending on the dose. Common side effects include impaired coordination, low blood pressure, difficulty speaking, and increased libido. Serious risks include dependence, withdrawal, and respiratory depression, especially when combined with opioids or alcohol. Xanax carries a boxed warning for the risk of abuse, dependence, and potentially fatal respiratory depression when used with other central nervous system (CNS) depressants.

WARNING: SUICIDAL THOUGHTS AND BEHAVIORS

Increased risk of suicidal thinking and behavior in children, adolescents and young adults taking antidepressants.

Monitor for worsening and emergence of suicidal thoughts and behaviors.

WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS; ABUSE, MISUSE, AND ADDICTION; and DEPENDENCE AND WITHDRAWAL REACTIONS

Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.

The use of benzodiazepines, including Xanax, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Before prescribing Xanax and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction.

• Abrupt discontinuation or rapid dosage reduction of Xanax after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risk of withdrawal reactions, use a gradual taper to discontinue Xanax or reduce the dosage.
