What is Bupropion and how is it used?

Bupropion is a prescription medicine used to treat the symptoms of major depression and seasonal affective disorder. Bupropion may be used alone or with other medications.

Bupropion belongs to a class of drugs called AntidepressantsDopamine Reuptake Inhibitors, Antidepressants, Other, Smoking Cessation Aids.


BUPROPION (bupropion hydrochloride) is indicated for the treatment of major depressive disorder (MDD), as defined by the Diagnostic and Statistical Manual (DSM).

The efficacy of BUPROPION in the treatment of a major depressive episode was established in two 4-week controlled inpatient trials and one 6-week controlled outpatient trial of adult subjects with MDD [see Clinical Studies].


General Instructions For Use

To minimize the risk of seizure, increase the dose gradually [see WARNINGS AND PRECAUTIONS]. Increases in dose should not exceed 100 mg/day in a 3-day period. BUPROPION Tablets should be swallowed whole and not crushed, divided, or chewed. BUPROPION may be taken with or without food.

The recommended starting dose is 200 mg/day, given as 100 mg twice daily. After 3 days of dosing, the dose may be increased to 300 mg/day, given as 100 mg 3 times daily, with at least 6 hours between successive doses. Dosing above 300 mg/day may be accomplished using the 75or 100-mg tablets.

A maximum of 450 mg/day, given in divided doses of not more than 150 mg each, may be considered for patients who show no clinical improvement after several weeks of treatment at 300 mg/day. Administer the 100-mg tablet 4 times daily to not exceed the limit of 150 mg in a single dose.

It is generally agreed that acute episodes of depression require several months or longer of antidepressant drug treatment beyond the response in the acute episode. It is unknown whether the dose of BUPROPION needed for maintenance treatment is identical to the dose that provided an initial response. Periodically reassess the need for maintenance treatment and the appropriate dose for such treatment.

Dose Adjustment In Patients With Hepatic Impairment

In patients with moderate to severe hepatic impairment (Child-Pugh score: 7 to 15), the maximum dose of BUPROPION is 75 mg/day. In patients with mild hepatic impairment (Child-Pugh score: 5 to 6), consider reducing the dose and/or frequency of dosing [see Use In Specific PopulationsCLINICAL PHARMACOLOGY].

Dose Adjustment In Patients With Renal Impairment

Consider reducing the dose and/or frequency of BUPROPION in patients with renal impairment (Glomerular Filtration Rate less than 90 mL/min) [see Use In Specific PopulationsCLINICAL PHARMACOLOGY].

Switching A Patient To Or From A Monoamine Oxidase Inhibitor (MAOI) Antidepressant

At least 14 days should elapse between discontinuation of an MAOI intended to treat depression and initiation of therapy with BUPROPION. Conversely, at least 14 days should be allowed after stopping BUPROPION before starting an MAOI antidepressant [see CONTRAINDICATIONSDRUG INTERACTIONS].

Use Of BUPROPION With Reversible MAOIs Such As Linezolid Or Methylene Blue

Do not start BUPROPION in a patient who is being treated with a reversible MAOI such as linezolid or intravenous methylene blue. Drug interactions can increase the risk of hypertensive reactions. In a patient who requires more urgent treatment of a psychiatric condition, non-pharmacological interventions, including hospitalization, should be considered [see CONTRAINDICATIONSDRUG INTERACTIONS].

In some cases, a patient already receiving therapy with BUPROPION may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue treatment are judged to outweigh the risks of hypertensive reactions in a particular patient, BUPROPION should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for 2 weeks or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with BUPROPION may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue.

The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with BUPROPION is unclear. The clinician should, nevertheless, be aware of the possibility of a drug interaction with such use [see CONTRAINDICATIONSDRUG INTERACTIONS].
