"What are antidepressants and how do they work?
Antidepressants are a class of drugs that reduce symptoms of depressive disorders by correcting chemical imbalances of neurotransmitters in the brain. Chemical imbalances may be respo"...
WELLBUTRIN (bupropion hydrochloride) is indicated for the treatment of major depressive disorder (MDD), as defined by the Diagnostic and Statistical Manual (DSM).
The efficacy of WELLBUTRIN 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].
DOSAGE AND ADMINISTRATION
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 per day in a 3-day period. WELLBUTRIN Tablets should be swallowed whole and not crushed, divided, or chewed. WELLBUTRIN may be taken with or without food.
The recommended starting dose is 200 mg per day, given as 100 mg twice daily. After 3 days of dosing, the dose may be increased to 300 mg per day, given as 100 mg 3 times daily, with at least 6 hours between successive doses. Dosing above 300 mg per day may be accomplished using the 75-or 100-mg tablets.
A maximum of 450 mg per 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 per 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 WELLBUTRIN 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 to15), the maximum dose of WELLBUTRIN is 75 mg per 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 Populations and CLINICAL PHARMACOLOGY].
Dose Adjustment In Patients With Renal Impairment
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 WELLBUTRIN. Conversely, at least 14 days should be allowed after stopping WELLBUTRIN before starting an MAOI antidepressant [see CONTRAINDICATIONS and DRUG INTERACTIONS].
Use Of WELLBUTRIN With Reversible MAOIs Such As Linezolid Or Methylene Blue
Do not start WELLBUTRIN 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 CONTRAINDICATIONS and DRUG INTERACTIONS].
In some cases, a patient already receiving therapy with WELLBUTRIN 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, WELLBUTRIN 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 WELLBUTRIN 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 WELLBUTRIN is unclear. The clinician should, nevertheless, be aware of the possibility of a drug interaction with such use [see CONTRAINDICATIONS and DRUG INTERACTIONS].
