About Wellbutrin SR
Wellbutrin SR is a prescription-only medication in Australia that contains the active ingredient bupropion. It belongs to the class of atypical antidepressants and is formulated as a sustained-release (SR) pill, typically supplied in 150 mg tablets. The drug is approved for the treatment of major depressive disorder and, in some jurisdictions, for smoking cessation, though the latter indication is not approved for this specific SR formulation in Australia. By delivering bupropion gradually over time, Wellbutrin SR helps maintain steadier blood concentrations, which can improve mood, increase energy, and reduce the urge to smoke.
What is Generic Wellbutrin SR (Bupropion)?
Generic Wellbutrin SR (bupropion) is the sustained-release version of the atypical antidepressant bupropion hydrochloride. It was first approved by the Therapeutic Goods Administration (TGA) in Australia in the early 2000s as a treatment for major depressive disorder. The medication is classified as a Schedule 4 (prescription-only) product, meaning it can be dispensed only with a valid prescription from a qualified prescriber. As a generic, it contains the same amount of bupropion as the branded Wellbutrin SR tablets and must meet the same bio-equivalence standards set by the TGA, ensuring comparable efficacy and safety while often offering a lower price point than the branded counterpart.
How Wellbutrin SR Works
Bupropion’s mechanism of action is distinct from most other antidepressants. It primarily inhibits the reuptake of two neurotransmitters-dopamine and norepinephrine-by blocking their transporters on presynaptic neurons. This results in increased synaptic concentrations of these catecholamines, which are thought to play key roles in mood regulation, motivation, and reward pathways.
In addition, bupropion is a weak antagonist of nicotinic acetylcholine receptors. By dampening the activity of these receptors, the drug reduces the reinforcing effects of nicotine, which underlies its use in smoking-cessation programs (though the SR formulation is not approved for that purpose in Australia).
Pharmacokinetically, the SR tablet releases bupropion over roughly 12 hours, leading to a smoother plasma-level curve compared with immediate-release formulations. Peak concentrations are usually reached 3-4 hours after ingestion, and the drug’s half-life averages 21 hours, allowing once-twice-daily dosing. Bupropion is metabolized mainly by the cytochrome P450 enzyme CYP2B6 into active metabolites (hydroxy-bupropion and threohydrobupropion), which contribute to its therapeutic effects. Excretion occurs primarily via the kidneys.
Why Wellbutrin SR Is Used for Mental Health Conditions
-
Major Depressive Disorder (MDD) Why effective: By boosting dopamine and norepinephrine, bupropion alleviates depressive symptoms such as low mood, anhedonia, and fatigue, especially in patients who experience insufficient response to serotonergic agents. Guideline position: The Australian Clinical Practice Guidelines for Depression list bupropion (including SR) as a second-line option or as part of combination therapy when first-line SSRIs or SNRIs are ineffective or not tolerated. Comparison: Unlike SSRIs, bupropion has a lower risk of sexual dysfunction and weight gain, making it attractive for patients concerned about these side effects.
-
Seasonal Affective Disorder (SAD) Why effective: The dopaminergic activity may counteract the reduced daylight-induced deficits in reward processing that characterize SAD. Guideline position: Some clinicians use bupropion SR off-label for SAD, mirroring evidence from North American trials; however, it remains an off-label approach in Australia.
-
Adjunctive Therapy for Bipolar Depression Why effective: Bupropion’s lack of potent serotonergic activity reduces the risk of triggering mania, a concern with many antidepressants. Guideline position: Used cautiously as an adjunct, often alongside mood stabilisers, when depressive episodes persist despite optimal bipolar management.
-
Smoking Cessation (off-label in Australia for SR) Why effective: Antagonism of nicotinic receptors reduces nicotine cravings and withdrawal symptoms. While the immediate-release (IR) formulation is approved for this purpose elsewhere, SR tablets have demonstrated comparable efficacy in clinical trials but are not formally approved for smoking cessation in Australia.
Off-Label and Investigational Uses of Wellbutrin SR
Research has explored bupropion SR in several off-label contexts, including attention-deficit/hyperactivity disorder (ADHD) and weight-loss programmes. Small randomized controlled trials suggest modest improvement in ADHD symptoms, likely related to enhanced dopaminergic transmission, but larger studies are needed to confirm safety and efficacy. In obesity management, bupropion combined with naltrexone (a separate approved product) has shown weight-reduction benefits; however, bupropion SR alone has produced inconsistent results.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Wellbutrin SR Right for You?
Wellbutrin SR is generally suited for adults diagnosed with major depressive disorder who have not achieved remission with first-line serotonergic agents or who experience undesirable side effects such as sexual dysfunction or weight gain. It may also be appropriate for patients with a history of smoking who are seeking an additional tool to aid cessation, provided a prescriber deems it suitable.
Special populations require careful consideration:
- Elderly patients: Age-related reductions in hepatic metabolism can increase plasma levels; dose reductions are often recommended.
- Pregnancy and lactation: Bupropion crosses the placenta and is excreted in breast milk; most Australian guidelines advise using it only when the potential benefit outweighs the risk.
- Renal or hepatic impairment: Severe dysfunction necessitates dose adjustment or avoidance, as clearance of bupropion and its active metabolites may be impaired.
Patients with a personal or family history of seizures should discuss alternatives, because bupropion lowers the seizure threshold in a dose-dependent manner.
Taking Wellbutrin SR Effectively
- Dosing schedule: The typical adult regimen starts at 150 mg once daily in the morning, increased to 150 mg twice daily (morning and early afternoon) after at least three days, to minimise insomnia.
- Food interactions: The SR tablet can be taken with or without food; however, taking it with a light meal may reduce gastrointestinal upset.
- Timing: Because the formulation releases medication over many hours, avoid taking the second dose after 4 p.m. to prevent sleep disturbances.
- Missed dose: If you forget a dose and it is less than 8 hours until the next scheduled dose, skip the missed tablet and resume the regular schedule. Do not double-dose.
- Travel: Carry the medication in its original container with the prescription label; a short-term supply (up to 30 days) is usually acceptable for personal use when traveling abroad, but check the destination country’s regulations.
Understanding Side Effects and How to Manage Them
Common adverse effects of Wellbutrin SR are linked to its pharmacological profile:
- Insomnia: Resulting from heightened norepinephrine activity. Manage by taking the first dose early in the morning and avoiding stimulants (caffeine, nicotine) in the evening.
- Dry mouth: An anticholinergic-like effect. Sip water frequently, chew sugar-free gum, or use saliva-stimulating lozenges.
- Headache: May stem from vasoconstriction caused by catecholamine increase. Over-the-counter acetaminophen can be used unless contraindicated.
- Tremor: Dopaminergic stimulation can produce fine motor tremor. If persistent, discuss dose adjustment with your prescriber.
Serious but less frequent reactions include seizures, hypertensive crisis, and severe allergic reactions (e.g., rash, angioedema). If you experience a seizure, sudden high blood pressure, or signs of an allergic reaction, seek emergency medical attention immediately.

Frequently Asked Questions
-
How long does it take for Wellbutrin SR to start improving mood? Most patients notice a modest lift in energy and motivation within the first week, but full antidepressant effects often emerge after 4-6 weeks of consistent dosing.
-
Can I switch from an immediate-release bupropion to the SR formulation? Transitioning is possible but should be supervised by a prescriber; typically the total daily dose is kept the same while adjusting timing to maintain therapeutic levels.
-
Is Wellbutrin SR safe to use with other antidepressants? Combining bupropion with certain serotonergic agents can increase the risk of serotonin syndrome. Your clinician will review all current medications before initiating combination therapy.
-
What should I do if I experience mild insomnia? Try taking the first dose earlier in the morning and avoid caffeine after lunch. If insomnia persists, inform your prescriber; a dose reduction or timing adjustment may be warranted.
-
Does Wellbutrin SR cause weight loss? Some patients experience modest weight reduction, likely due to appetite suppression from increased norepinephrine. However, weight change is not a guaranteed or primary therapeutic outcome.
-
Can I use Wellbutrin SR while trying to quit smoking? Although the SR formulation is not officially approved for cessation in Australia, clinicians sometimes prescribe it off-label for smokers who have responded well to bupropion IR elsewhere. This decision requires careful monitoring.
-
How does Wellbutrin SR differ from Wellbutrin XL? SR releases the drug over roughly 12 hours and is usually taken twice daily, whereas XL provides a 24-hour release and is taken once daily. Both contain the same active ingredient but have different dosing schedules.
-
Is it appropriate for teenagers with depression? Bupropion is not routinely approved for children under 18 in Australia for depression. Use in adolescents should be limited to specialist-guided cases where benefits outweigh risks.
-
Will alcohol worsen side effects? Alcohol can lower the seizure threshold further and may intensify insomnia. Moderate consumption is generally discouraged while on Wellbutrin SR.
-
Can Wellbutrin SR be taken during a migraine? Since bupropion can cause vasoconstriction, some clinicians advise caution in patients with frequent migraines; discuss your migraine history with your prescriber.
-
What monitoring is required? Baseline blood pressure, mood assessment, and periodic evaluation of seizure risk are standard. Follow-up visits are typically scheduled every 4-6 weeks during the titration phase.
