* Incidence of Seizure With Bupropion Use: Bupropion is associated with seizures in approximately 0.4% (4/1,000) of patients treated at doses up to 450 mg per day. The estimated seizure incidence for Bupropion increases almost 10-fold between 450 and 600 mg per day.

<b>Hypertension <b>
 
* Treatment with Bupropion can result in elevated blood pressure and [[hypertension]]. Assess blood pressure before initiating treatment with Bupropion, and monitor periodically during treatment. The risk of hypertension is increased if Bupropion is used concomitantly with MAOIs or other drugs that increase dopaminergic or noradrenergic activity [see Contraindications].
 
* Data from a comparative trial of the sustained-release formulation of bupropion HCl, nicotine transdermal system (NTS), the combination of sustained-release bupropion plus NTS, and placebo as an aid to smoking cessation suggest a higher incidence of treatment-emergent hypertension in patients treated with the combination of sustained-release bupropion and NTS. In this trial, 6.1% of subjects treated with the combination of sustained-release bupropion and NTS had treatment‑emergent hypertension compared to 2.5%, 1.6%, and 3.1% of subjects treated with sustained-release bupropion, NTS, and placebo, respectively. The majority of these subjects had evidence of pre-existing hypertension. Three subjects (1.2%) treated with the combination of sustained-release bupropion and NTS and 1 subject (0.4%) treated with NTS had study medication discontinued due to hypertension compared with none of the subjects treated with sustained-release bupropion or placebo. Monitoring of blood pressure is recommended in patients who receive the combination of bupropion and nicotine replacement.
 
* In a clinical trial of bupropion immediate-release in MDD subjects with stable [[congestive heart failure]] (N = 36), bupropion was associated with an exacerbation of pre-existing [[hypertension]] in 2 subjects, leading to discontinuation of bupropion treatment. There are no controlled trials assessing the safety of bupropion in patients with a recent history of [[myocardial infarction]] or unstable cardiac disease.
 
<b>Activation of Mania/Hypomania<b>
 
* Antidepressant treatment can precipitate a [[manic]], mixed, or [[hypomanic]] manic episode. The risk appears to be increased in patients with [[bipolar disorder]] or who have risk factors for bipolar disorder. Prior to initiating bupropion, screen patients for a history of [[bipolar disorder]] and the presence of risk factors for bipolar disorder (e.g., [[family history of bipolar disorder]], [[suicide]], or [[depression]]). Bupropion is not approved for use in treating [[bipolar depression]].
 
<b>Psychosis and Other Neuropsychiatric Reactions<b>
 
* Depressed patients treated with bupropion have had a variety of neuropsychiatric signs and symptoms, including [[delusions]], [[hallucinations]], [[psychosis]], concentration disturbance, [[paranoia]], and [[confusion]]. Some of these patients had a diagnosis of [[bipolar disorder]]. In some cases, these symptoms abated upon dose reduction and/or withdrawal of treatment. Instruct patients to contact a healthcare professional if such reactions occur.
 
<b>Hypersensitivity Reactions<b>
 
* Anaphylactoid/anaphylactic reactions have occurred during clinical trials with bupropion. Reactions have been characterized by [[pruritus]], [[urticaria]], [[angioedema]], and [[dyspnea]] requiring medical treatment. In addition, there have been rare, spontaneous postmarketing reports of [[erythema multiforme]], [[Stevens‑Johnson]] syndrome, and [[anaphylactic shock]] associated with [[bupropion]]. Instruct patients to discontinue bupropion and consult a healthcare provider if they develop an allergic or anaphylactoid/anaphylactic reaction (e.g., [[skin rash]], [[pruritus]], [[hives]], [[chest pain]], [[edema]], and shortness of breath) during treatment.
 
* There are reports of [[arthralgia]], [[myalgia]], fever with rash and other [[serum sickness]]-like symptoms suggestive of [[delayed hypersensitivity]].

Black Box Warning

Suicidal thoughts and behaviours; and neuropsychiatry reactions
See full prescribing information for complete Boxed Warning.
*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.
  • Serious neuropsychiatric events have been reported in patients taking bupropion for smoking cessation.

Overview

Bupropion is a tetracyclics and unicyclics that is FDA approved for the {{{indicationType}}} of major depressive disorder (MDD)depression, associated with seasonal affective disorder; prophylaxis. There is a Black Box Warning for this drug as shown here. Common adverse reactions include suicidal thoughts and behaviors in adolescents and young adults, neuropsychiatric symptoms and suicide risk in smoking cessation treatment, seizure, hypertension, activation of mania or hypomania, psychosis and other neuropsychiatric reactions, hypersensitivity reactions.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Major depressive disorder (MDD)

  • 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. 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 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 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.

*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.
  • Serious neuropsychiatric events have been reported in patients taking bupropion for smoking cessation.

Suicidal Thoughts and Behaviors in Children, Adolescents, and Young Adults

  • Worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior.
  • Pooled analyses of short‑term placebo‑controlled trials of antidepressant drugs (selective serotonin reuptake inhibitors [SSRIs] and others) show that these drugs *Increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18 to 24) with MDD and other psychiatric disorders. Short-term clinical trials did not show an increase in the risk of suicidality with antidepressants compared with placebo in adults beyond age 24; there was a reduction with antidepressants compared with placebo in adults aged 65 and older.
  • The pooled analyses of placebo-controlled trials in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short‑term trials of 9 antidepressant drugs in over 4,400 subjects. The pooled analyses of placebo‑controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short‑term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 subjects. There was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger subjects for almost all drugs studied. There were differences in absolute risk of suicidality across the different indications, with the highest incidence in MDD. The risk differences (drug vs. placebo), however, were relatively stable within age strata and across indications. These risk differences (drug-placebo difference in the number of cases of suicidality per 1,000 subjects treated) are provided in Table 1
