Bupropion, commonly sold as brand names Wellbutrin and Zyban, is an antidepressant medication classified as a norepinephrine-dopamine reuptake inhibitor (NDRI). It is important to discuss medications used in conjunction with bupropion with your doctor, as adverse interactions can have dangerous consequences.
Bupropion is commonly prescribed in the treatment of depression, including major depressive disorder, bipolar depression, and seasonal affective disorder, under the brand name Wellbutrin XL.
Bupropion can be a helpful alternative for people experiencing unwanted side effects, such as sexual dysfunction, from alternative antidepressant medications.
Additionally, it can be prescribed for smoking cessation under the name brand Zyban.
Other brand names of bupropion include:
There are also "off-label" uses for bupropion. "Off-label" use of medication means that the Food and Drug Administration (FDA) has not yet approved its use for treating a particular condition. This often happens when there is insufficient clinical data to demonstrate efficacy.
Off-label uses for bupropion include:
Bupropion works by preventing the reuptake of norepinephrine and dopamine in the brain. Researchers continue to study why and how these neurotransmitters affect depression.
Clinical studies have shown bupropion medications such as Wellbutrin XL are helpful alternatives for those with major depressive disorder who do not respond to a traditional antidepressant drug. Approximately 25% of patients who were unsuccessful with a selective serotonin reuptake inhibitor (SSRI) found relief from depression symptoms with bupropion during a clinical study.
Early signs that the medication is working include better sleep, increased energy, and improved appetite. However, it can take up to 8 weeks to reach the full therapeutic effects.
Since bupropion is only available by prescription, it should be used as prescribed.
Bupropion medications are taken via oral administration in tablet form. Tablets are available in extended-release options, also known as sustained-release. Sustained-release bupropion tablets are designed to dissolve more slowly, allowing them to remain in the body for longer.
Extended-release options reduce the daily amount needed and are often taken in single doses. Wellbutrin XL, for example, may only need to be taken once a day, whereas other options may require taking the medication up to three times daily.
Extended-release tablets should never be crushed, cut, or chewed. Altering the tablet changes the way the medication metabolizes in the body.
Always talk to your healthcare provider if you miss a dose because sometimes, missed doses should be skipped. Taking an extra tablet can lead to seizures.
Because of bupropion's effects on energy levels, it is advised to avoid taking this medication near bedtime as it may cause insomnia.
How long the effects of bupropion last depends on the dosage and amount of times the medication has been taken. The longer bupropion is taken, the longer it will remain in the system.
The body eliminates this drug primarily through urine.
Studies have shown bupropion use can cause false positives for amphetamines on urine drug screens.
It is recommended that dosages be tapered down before stopping the use of bupropion to avoid withdrawal symptoms.
Withdrawal symptoms from bupropion may include:

These common side effects often dissipate but should still be monitored by a medical professional.

Additionally, seizures are more common in people with a pre existing seizure disorder or low seizure threshold, those using the medication in conjunction with alcohol or other substances, or those with another underlying medical risk factor.
Antidepressant medications occasionally cause critical psychological side effects, particularly for children and teenagers.
Psychological side effects may include:
Any changes in mood or behavior must be discussed with the prescribing doctor as soon as possible.
To prevent complications of taking bupropion, an evaluation should be completed that includes a full medical history before prescribing bupropion. This medical history should include any history of mental health diagnoses.
It is especially important to discuss with the doctor any history of bipolar disorder, alcohol use, eating disorder symptoms, suicidal problems, liver problems, kidney problems, or seizures. These conditions are linked to complications with bupropion use.
Bupropion use is not recommended during pregnancy or breastfeeding. Always tell your doctor if you are pregnant or planning to become pregnant before taking bupropion.
Drug interactions between bupropion and other medications can be fatal, so discussing any medications you’re currently taking with a medical professional is vital.
The use of alcohol in conjunction with bupropion has been linked to an increased risk of seizures. Seizure risk is also associated with higher dosages of bupropion and bupropion medications used in conjunction with one another.
Additional interactions increasing the risk of seizure include:
Bupropion should not be used within two weeks of taking a monoamine oxidase inhibitor (MAOI) medication.
St. John’s wort and certain vitamins, including B vitamins, sometimes suggested as natural aides for depression symptoms are linked to adverse interactions with bupropion. Therefore, any herbal or vitamin supplements you use should be discussed with a medical professional before taking bupropion.
Bupropion medications should be stored at room temperature in a closed container away from natural light. These medications should be discarded when they expire or are no longer being taken.
As with all prescription medication, bupropion should be stored out of the reach of children or teenagers.
