Pregnancy risk category C
FDA Box Warning
• Antidepressants increase risk of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder and other psychiatric disorders. Risk must be balanced with clinical need, as depression itself increases suicide risk. With patient of any age, observe closely for clinical worsening, suicidality, or unusual behavior changes. Advise family or caregiver to observe patient closely and communicate with prescriber as needed.
• Bupropion hydrobromide (Aplenzin) and bupropion hydrochloride (Budeprion SR, Budeprion XL, Buproban, Wellbutrin, Wellbutrin SR, and Wellbutrin XL) aren't approved for smoking cessation treatment, but bupropion hydrochloride under the names of Buproban and Zyban is approved for this use. Serious neuropsychiatric events, including but not limited to depression, suicidal ideation, suicide attempt, and completed suicide, have been reported in patients taking Buproban and Zyban for smoking cessation. Some cases may have been complicated by the signs and symptoms of nicotine withdrawal in patients who stopped smoking. Risks should be weighed against benefits of their use in smoking cessation.
• Drug isn't approved for use in pediatric patients.
Unclear. Thought to decrease neuronal reuptake of dopamine, serotonin, and norepinephrine in CNS. Action as smoking-cessation aid may result from noradrenergic or dopaminergic activity.

⊘Indications and dosages
Adults: Initially, 100 mg P.O. immediate-release tablet b.i.d. (morning and evening). After 3 days, may increase to 100 mg t.i.d. After 4 weeks, may increase to a maximum dosage of 450 mg/day in divided doses. No single dose should exceed 150 mg. With total daily dosage of 300 mg, wait at least 6 hours between doses; with total daily dosage of 450 mg, wait at least 4 hours between doses. Alternatively, give one 150-mg sustained-release tablet daily; increase to 150-mg sustained-release tablet b.i.d. based on clinical response. Or initially, 174 mg P.O. extended-release tablet daily in the morning; if 174-mg dose is adequately tolerated, increase to 348 mg extended-release tablet daily as early as day 4. An increase in dosage to maximum of 522 mg extended-release tablet daily, given as a single dose, may be considered for patients in whom no clinical improvement is noted after several weeks of treatment at 348 mg/day. Don't exceed single dose of 150 mg for immediate-release tablets, 522 mg for extended-release tablets, or 200 mg for sustained-release tablets.
➣ Smoking cessation
Adults: 150 mg P.O. sustained-release tablet (Zyban) or 150 mg extended-release tablet (Buproban) once daily for 3 days, then 150-mg sustained-release tablet b.i.d. for 7 to 12 weeks. Space doses at least 8 hours apart. Don't exceed maximum dosage of 300 mg daily.

Seasonal Affective Disorder
Availability (generic available)
- Monitor mood changes. Inform health care professional if patient demonstrates significant increase in anxiety, nervousness, or insomnia.
- Assess mental status and mood changes, especially during initial few months of therapy and during dose changes. Risk may be increased in children, adolescents, and adults ≤24 yrs. Inform health care professional if patient demonstrates significant increase in signs of depression (depressed mood, loss of interest in usual activities, significant change in weight and/or appetite, insomnia or hypersomnia, psychomotor agitation or retardation, increased fatigue, feelings of guilt or worthlessness, slowed thinking or impaired concentration, suicide attempt or suicidal ideation). Restrict amount of drug available to patient.
- Lab Test Considerations: Monitor hepatic and renal function closely in patients with kidney or liver impairment to prevent ↑ serum and tissue bupropion concentrations.
- May cause false-positive urine test for amphetamines.
Potential Nursing DiagnosesIneffective coping (Indications)
- Do not confuse bupropion with buspirone. Do not confuse Wellbutrin SR with Wellbutrin XL. Do not confuse Zyban with Diovan. Do not administer bupropion (Wellbutrin) with Zyban, which contain the same ingredients.
- Administer doses in equally spaced time increments during the day to minimize the risk of seizures. Risk of seizures increases fourfold in doses greater than 450 mg per day.
- May be initially administered concurrently with sedatives to minimize agitation. This is not usually required after the 1st wk of therapy.
- Insomnia may be decreased by avoiding bedtime doses. May require treatment during 1st wk of therapy.
- Nicotine patches, gum, inhalers, and spray may be used concurrently with bupropion.
- When converting from other brands of bupropion to Aplenzin 522 mg/day Aplenzin is equivalent to 450 mg/day bupropion HCl, 348 mg/day Aplenzin is equivalent to 300 mg/day bupropion HCl and 174 mg/day Aplenzin is equivalent to 150 mg/day bupropion HCl.
- Oral: Swallow sustained-release or extended-release tablets whole; do not break, crush, or chew.
- May be administered with food to lessen GI irritation.
- Seasonal Affective Disorder: Begin administration in autumn prior to the onset of depressive symptoms. Continue therapy through winter and begin to taper and discontinue in early spring.
- Instruct patient to take bupropion as directed. Take missed doses as soon as possible and space day’s remaining doses evenly at not less than 4-hr intervals. Missed doses for smoking cessation should be omitted. Do not double doses or take more than prescribed. May require 4 wk or longer for full effects. Do not discontinue without consulting health care professional. May require gradual reduction before discontinuation.
- May impair judgment or motor and cognitive skills. Caution patient to avoid driving and other activities requiring alertness until response to medication is known.
- Advise patient, family, and caregivers to look for suicidality, especially during early therapy or dose changes. Notify health care professional immediately if thoughts about suicide or dying, attempts to commit suicide, new or worse depression or anxiety, agitation or restlessness, panic attacks, insomnia, new or worse irritability, aggressiveness, acting on dangerous impulses, mania, or other changes in mood or behavior occur.
- Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken, to avoid alcohol during therapy and to consult with health care professional before taking other medications with bupropion, such as Zyban.
- Inform patient that frequent mouth rinses, good oral hygiene, and sugarless gum or candy may minimize dry mouth. If dry mouth persists for more than 2 wk, consult health care professional regarding use of saliva substitute.
- Advise patient to notify health care professional if rash or other troublesome side effects occur.
- Inform patient that unused shell of XL tablets may appear in stool; this is normal.
- Advise patient to use sunscreen and protective clothing to prevent photosensitivity reactions.
- Advise patient to notify health care professional of medication regimen before treatment or surgery.
- Instruct female patients to inform health care professional if pregnancy is planned or suspected or if breast feeding or planning to breast feed.
- Emphasize the importance of follow-up exams to monitor progress. Encourage patient participation in psychotherapy.
- Smoking Cessation: Smoking should be stopped during the 2nd week of therapy to allow for the onset of bupropion and to maximize the chances of quitting.
- Advise patient to stop taking bupropion and contact a health care professional immediately if agitation, depressed mood, and any changes in behavior that are not typical of nicotine withdrawal, or if suicidal thoughts or behavior occur.
- Increased sense of well-being.
- Renewed interest in surroundings. Acute episodes of depression may require several months of treatment.

I am on Wellbutrin for my ADHD and I was very stressed because of losing my social seating’s and friends by the fact that I am ADHD and just to show that I am well and I have nothing as such I stopped on the my meds to show off my side effect and then staged a party and some friends remained with me those who came from long distance after the party and almost for a week I lost on my meds…..and it turned opposite that I I started having serious vomiting seizures and I lost my self and was brought back to normal once I was again put back to meds….it’s something like boomerang happened I left medicine to reduce on my side effect and soon the left meds came with same side effects…how come this happen?…though I learned good that my friends were helpful….and it was me who took them wrong and they all blamed this to my ADHD and not me….
