Wellbutrin (bupropion hydrochloride) is an aminoketone-class antidepressant indicated for the treatment of major depressive disorder (MDD) and seasonal affective disorder (SAD). It functions as a norepinephrine-dopamine reuptake inhibitor (NDRI), distinguishing its mechanism from many SSRIs and SNRIs. This pharmacological profile offers a distinct side effect and efficacy pattern, making it a valuable option in individualized treatment plans for depression management.
Features
- Active ingredient: Bupropion hydrochloride
- Available in immediate-release (IR), sustained-release (SR), and extended-release (XL) formulations
- NDRI mechanism: inhibits neuronal reuptake of norepinephrine and dopamine
- Not associated with significant serotonergic activity or sexual dysfunction common to many antidepressants
- FDA-approved for major depressive disorder and prevention of seasonal affective disorder
- May also be used off-label for smoking cessation (as Zyban) and ADHD
Benefits
- Effective reduction of core depressive symptoms such as anhedonia, low energy, and concentration difficulties
- Lower incidence of weight gain and sexual dysfunction compared to many SSRIs
- May provide activating effects beneficial for patients with fatigue or hypersomnia
- Does not typically cause sedation, supporting daytime functioning
- Can be used as monotherapy or as an adjunct to other antidepressants to enhance efficacy or mitigate side effects
- Extended-release formulations support once-daily dosing, improving adherence
Common use
Wellbutrin is primarily prescribed for the management of major depressive disorder in adults. It is also approved for the prevention of depressive episodes in patients with a history of seasonal affective disorder. Clinicians may consider it when patients have not responded adequately to SSRIs, when sexual side effects or weight gain are significant concerns, or when an activating antidepressant profile is clinically indicated.
Dosage and direction
Dosage must be individualized based on patient response and tolerance. Treatment typically initiates at a lower dose to minimize the risk of adverse effects, particularly insomnia or agitation. For the XL formulation, the usual starting dose is 150 mg once daily in the morning, which may be increased to 300 mg daily after several days if tolerated. Maximum recommended dose is 450 mg per day, administered as a single dose. Tablets should be swallowed whole and not crushed, chewed, or divided. Dosing should be consistent and taken at the same time each day.
Precautions
Patients should be monitored for worsening depression, suicidality, or unusual changes in behavior, especially at treatment initiation or dosage adjustments. Use with caution in patients with hepatic or renal impairment, dose adjustment may be necessary. May lower seizure threshold; avoid in patients with a history of seizure disorder, eating disorders, or undergoing abrupt discontinuation of alcohol or sedatives. May increase blood pressure; periodic monitoring recommended. Inform healthcare provider of all medications being taken.
Contraindications
Wellbutrin is contraindicated in patients with a seizure disorder; current or prior diagnosis of bulimia or anorexia nervosa; undergoing abrupt discontinuation of alcohol, benzodiazepines, barbiturates, or antiepileptic drugs; use of monoamine oxidase inhibitors (MAOIs) within the last 14 days; and known hypersensitivity to bupropion or any component of the formulation.
Possible side effects
Common side effects may include dry mouth, nausea, headache, insomnia, dizziness, and increased sweating. Less frequently, tremor, rash, tinnitus, anxiety, agitation, and constipation may occur. Although rare, serious side effects can include seizures, hypertension, allergic reactions, angle-closure glaucoma, and severe skin reactions. Any unusual or severe symptoms should be reported to a healthcare provider immediately.
Drug interaction
Bupropion is metabolized primarily by CYP2B6. Concomitant use with CYP2B6 inhibitors (e.g., ticlopidine, clopidogrel) may increase bupropion exposure and risk of adverse effects. Inducers of CYP2B6 (e.g., ritonavir, lopinavir, carbamazepine) may decrease bupropion levels. Use caution with drugs that lower seizure threshold (e.g., antipsychotics, antidepressants, systemic corticosteroids). May interact with dopaminergic drugs. Avoid concomitant use with MAOIs due to increased risk of hypertensive crisis.
Missed dose
If a dose is missed, it should be taken as soon as remembered unless it is close to the time of the next scheduled dose. In that case, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for a missed one, as this may increase the risk of adverse effects, including seizure.
Overdose
Overdose may lead to severe outcomes, including seizures, hallucinations, tachycardia, arrhythmias, fever, muscle rigidity, hypotension, coma, and respiratory failure. Fatal outcomes have been reported, often involving multiple drug ingestion. In case of suspected overdose, seek immediate medical attention or contact a poison control center. Management is supportive and symptomatic; there is no specific antidote.
Storage
Store at room temperature, 20°C to 25°C (68°F to 77°F), in a tightly closed container. Protect from light, moisture, and excessive heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Dispose of unused medication properly via a drug take-back program or according to FDA guidelines.

Reviews
Clinical studies and patient reports indicate that Wellbutrin is often effective in alleviating depressive symptoms, particularly lack of energy, motivation, and focus. Many users appreciate the relative absence of weight gain and sexual side effects. However, individual responses vary; some patients may experience agitation, insomnia, or other side effects that limit tolerability. It is essential that treatment be supervised by a healthcare professional to ensure safety and efficacy.
