WARNING: SUICIDAL THOUGHTS AND BEHAVIORS; AND NEUROPSYCHIATRIC REACTIONS

SUICIDALITY AND ANTIDEPRESSANT DRUGS

Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term trials. These trials did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in subjects over age 24; there was a reduction in risk with antidepressant use in subjects aged 65 and older [see Warnings and Precautions (5.1)].

In patients of all ages who are started on antidepressant therapy, monitor closely for worsening and for emergence of suicidal thoughts and behaviors. Advise families and caregivers of the need for close observation and communication with the prescriber. Bupropion hydrochloride extended-release tablet (XL) is not approved for use in pediatric patients [see Warnings and Precautions (5.1)].

1 INDICATIONS AND USAGE

Bupropion hydrochloride extended-release tablets (XL) are indicated for the treatment of major depressive disorder (MDD), as defined by the Diagnostic and Statistical Manual (DSM).

The efficacy of the immediate-release formulation of bupropion was established in two 4-week controlled inpatient trials and one 6-week controlled outpatient trial of adult patients with MDD. The efficacy of the sustained-release formulation of bupropion in the maintenance treatment of MDD was established in a long-term (up to 44 weeks), placebo-controlled trial in patients who had responded to bupropion in an 8-week study of acute treatment [see Clinical Studies (14)].

The physician who elects to use bupropion hydrochloride extended-release tablets (XL) for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

2 DOSAGE AND ADMINISTRATION

2.1 General Instructions for Use

One tablet (450 mg) of bupropion hydrochloride extended-release tablet (XL) should be taken once daily without regard to meals. Bupropion hydrochloride extended-release tablets (XL) should be swallowed whole and not crushed, divided, or chewed.

2.2 Initial Treatment with Bupropion Hydrochloride Extended-Release Tablets (XL)

Do not initiate treatment with bupropion hydrochloride extended-release tablets (XL) because the 450-mg tablet is the only available dose formulation. Use another bupropion formulation for initial dose titration (referring to prescribing information of other bupropion products).

Bupropion hydrochloride extended-release tablets (XL) can be used in patients who are receiving 300 mg/day of another bupropion formulation for at least 2 weeks, and require a dosage of 450 mg/day.

Patients who are currently being treated with other bupropion products at 450 mg/day can be switched to an equivalent dose of bupropion hydrochloride extended-release tablets (XL) once daily.

2.3 Maintenance Treatment with Bupropion Hydrochloride Extended-Release Tablets (XL)

It is generally agreed that acute episodes of depression require several months or longer of sustained antidepressant treatment beyond the response in the acute episode. It is unknown whether the 450-mg dose 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.

2.4 To Discontinue Bupropion Hydrochloride Extended-Release Tablets (XL), Taper the Dose

Because the 450-mg tablet is the only available dose formulation, use another bupropion formulation for tapering the dose prior to discontinuation (referring to prescribing information of other bupropion products).

2.5 Patients with Impaired Hepatic Function

Because there is no lower dose strength for bupropion hydrochloride extended-release tablets (XL), bupropion hydrochloride extended-release tablets (XL) are not recommended in patients with hepatic impairment [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)].

2.6 Patients with Impaired Renal Function

Because there is no lower dose strength for bupropion hydrochloride extended-release tablets (XL), bupropion hydrochloride extended-release tablets (XL) is not recommended in patients with renal impairment [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

2.7 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 hydrochloride extended-release tablets (XL). Conversely, at least 14 days should be allowed after stopping bupropion hydrochloride extended-release tablets (XL) before starting an MAOI antidepressant [see Contraindications (4) and Drug Interactions (7.6)].

2.8 Use of Bupropion Hydrochloride Extended-Release Tablets (XL) with Reversible MAOIs Such as Linezolid or Methylene Blue

Do not start bupropion hydrochloride extended-release tablets (XL) 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, nonpharmacological interventions, including hospitalization, should be considered [see Contraindications (4)].

In some cases, a patient already receiving therapy with bupropion hydrochloride extended-release tablets (XL) 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 hydrochloride extended-release tablets (XL) 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 hydrochloride extended-release tablets (XL) may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue.

The risk of administering methylene blue by nonintravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with bupropion hydrochloride extended-release tablets (XL) is unclear. The clinician should, nevertheless, be aware of the possibility of a drug interaction with such use [see Contraindications (4) and Drug Interactions (7.6)].

3 DOSAGE FORMS AND STRENGTHS

4 CONTRAINDICATIONS

  • Bupropion hydrochloride extended-release tablets (XL) are contraindicated in patients with a seizure disorder [see Warnings and Precautions (5.3) ].
  • Bupropion hydrochloride extended-release tablets (XL) are contraindicated in patients treated currently with other bupropion products because the incidence of seizure is dose dependent [see Warnings and Precautions (5.3) ].
  • Bupropion hydrochloride extended-release tablets (XL) are contraindicated in patients with a current or prior diagnosis of bulimia or anorexia nervosa because a higher incidence of seizures was observed in such patients treated with bupropion [see Warnings and Precautions (5.3) ].
  • Bupropion hydrochloride extended-release tablets (XL) are contraindicated in patients undergoing abrupt discontinuation of alcohol, benzodiazepines, barbiturates, and antiepileptic drugs [see Warnings and Precautions (5.3) and Drug Interactions (7.3) ].
  • The use of MAOIs (intended to treat psychiatric disorders) concomitantly with bupropion hydrochloride extended-release tablets (XL) or within 14 days of discontinuing treatment with bupropion hydrochloride extended-release tablets (XL) are contraindicated. There is an increased risk of hypertensive reactions when bupropion hydrochloride extended-release tablets (XL) are used concomitantly with MAOIs. The use of bupropion hydrochloride extended-release tablets (XL) within 14 days of discontinuing treatment with an MAOI is also contraindicated. Starting bupropion hydrochloride extended-release tablets (XL) in a patient treated with reversible MAOIs such as linezolid or intravenous methylene blue is contraindicated [see Dosage and Administration (2.8), Warnings and Precautions (5.4), and Drug Interactions (7.6) ].
  • Bupropion hydrochloride extended-release tablets (XL) are contraindicated in patients with known hypersensitivity to bupropion or the other ingredients of bupropion hydrochloride extended-release tablets (XL). Anaphylactoid/anaphylactic reactions and Stevens-Johnson syndrome have been reported [see Warnings and Precautions (5.8) ].
