Wellbutrin XL (bupropion) is a commonly prescribed antidepressant medication. It is used to treat major depressive disorder (MDD), seasonal affective disorder (SAD), and smoking cessation. Wellbutrin XL is an extended-release formulation of bupropion, which means that it is designed to release the drug slowly over a prolonged period. While Wellbutrin XL can be effective in treating depression, it is important to be aware of the risks associated with overdose. The severity of a Wellbutrin XL overdose can vary depending on the amount ingested, with doses exceeding 600 mg considered dangerous for adults. Seizures are the most common and deadly effect of Wellbutrin XL overdose, with other symptoms including tachycardia, agitation, and GI issues.
| Characteristics | Values |
|---|---|
| Overdose amount | 450 mg is the typical overdose amount, but this can vary depending on the formulation and the individual. Some sources state that doses above 600 mg are considered an overdose. |
| Symptoms | Seizures, tachycardia, agitation, vomiting, tremors, hypertension, hypotension, hallucinations, coma, and more. |
| Treatment | There is no antidote, so treatment focuses on supportive care and managing symptoms. Intubation, sedation, and whole bowel irrigation may be used to manage agitation and seizures. Activated charcoal can be used to decontaminate the stomach if the patient presents soon after overdose. |
| Prevention | Bupropion should only be taken as prescribed. Do not take more or less than directed by your doctor. Keep out of the reach of children. |

Wellbutrin XL is used to treat depression and seasonal affective disorder
Wellbutrin XL is used to treat major depressive disorder (MDD) in adults. MDD is also referred to as depression, and it is characterised by persistent and intense feelings of sadness that interrupt daily life. Symptoms of depression vary from person to person. Wellbutrin XL is also used to prevent seasonal affective disorder (SAD) in adults. SAD is a type of recurrent depressive disorder that occurs during a particular season, typically the winter months.
Wellbutrin XL is one of two forms of Wellbutrin, the other being Wellbutrin SR. Wellbutrin is the brand name for the drug bupropion, an antidepressant medication. Bupropion is also available under other brand names, including Zyban, Aplenzin, Budeprion XL, and Forfivo XL. Wellbutrin XL is an extended-release formulation, meaning it releases the active drug slowly over time. The typical starting dosage for Wellbutrin XL when treating depression is 150 mg once per day, which a doctor may increase to 300 mg once per day after four days. The maximum recommended dosage is 450 mg once per day.
When used to prevent SAD, Wellbutrin XL is typically taken once daily in the morning, beginning in early autumn, continuing through the winter, and stopping in early spring. The dosage is usually 300 mg once daily, though it may be reduced to 150 mg once daily before discontinuing treatment. The timing of initiation and treatment duration for SAD should be individualised according to the patient's historical pattern of seasonal depressive episodes.
While Wellbutrin XL is effective in treating depression and preventing SAD, it is important to be aware of potential side effects and risks. Bupropion overdose is a known cause of seizures, with potentially deadly cardiovascular effects in extreme cases. Overdose can also lead to tachycardia, agitation, and delayed seizures occurring up to 24 hours after ingestion. If you suspect an overdose, call the poison control helpline or, in an emergency, dial 911.

It is available in 150 mg and 300 mg strengths
Wellbutrin XL (bupropion) is available as a sustained-release (SR) and extended-release (XL) tablet. The dose and frequency of medication are dependent on the patient's condition and their doctor's advice. Wellbutrin XL is usually taken once daily in the morning, and doses should be at least 24 hours apart.
The dose of Wellbutrin XL varies depending on the patient's needs and their doctor's recommendations. The tablet is available in 150 mg and 300 mg strengths. The 150 mg tablet is typically prescribed to be taken once a day, while the 300 mg tablet is usually taken twice a day, with doses at least 8 hours apart. It is important to note that the dosage may vary depending on the patient's response to the medication and their doctor's assessment.
Wellbutrin XL is a type of medication known as an antidepressant. It is commonly used to treat major depressive disorder (MDD) and seasonal affective disorder (SAD). It can also aid in smoking cessation. The drug works by increasing certain types of activity in the brain, specifically by inhibiting the reuptake of norepinephrine and dopamine. This allows these neurotransmitters to accumulate, which can improve mood and a sense of well-being.
It is important to take Wellbutrin XL exactly as directed by a doctor or pharmacist. Taking more or less of the medication than prescribed can lead to an overdose. An overdose occurs when there is an accumulation of bupropion in the body, resulting in various physical and psychological symptoms. The severity and duration of symptoms depend on the dose taken. Seizures are the most common and life-threatening symptom of Wellbutrin XL overdose. Other symptoms include vomiting, tachycardia, tremors, agitation, and confusion.
In the event of a suspected overdose, it is crucial to call the poison control helpline or emergency services, depending on the severity of the situation. Initial priorities for overdose patients include assessing airway, breathing, and circulation. Intravenous access, continuous cardiac monitoring, and frequent vital sign checks are also important. Treatment for Wellbutrin XL overdose is primarily supportive care, as there is no direct antidote.

Doctors will prescribe a low dosage initially and adjust it over time
An overdose of Wellbutrin XL (bupropion) of greater than 600 mg requires admission to a hospital for 24 hours, as seizures have been reported up to one day after ingestion. Wellbutrin is a common norepinephrine and dopamine reuptake inhibitor used for depression and smoking cessation. In overdose, it can lead to cardiovascular and central nervous system toxicity, resulting in dysthymias and seizures.
Doctors will often prescribe a low dosage of medication initially and adjust it over time. This approach is recommended when starting a new medication for a chronic condition that is not life-threatening or producing severe symptoms. The benefits of this approach include the potential placebo effect, as patients know they are receiving treatment, albeit at a very low dose. This can also lead to cost savings, as using half a tablet of a medication can amount to considerable savings over time.
Additionally, starting with a low dose engages patients in finding the best dosage for them. This shared decision-making has been associated with improved health-related behaviours and clinical outcomes. It also allows doctors to gradually increase the dosage over time to ensure that the medication is well-tolerated by the patient and to minimise the risk of side effects.
Patient-specific factors, such as age, weight, kidney and liver function, and comorbidities, can also impact the prescribed dosage. For example, younger and older patients may not be able to tolerate the full dosage of some medications and may be instructed to take a smaller dose. Similarly, patients with low or high body weight may have their dosage adjusted to ensure the medication is effective and well-tolerated.
Furthermore, medication dosage may be adjusted based on individual responses and reactions. If a patient has been taking medication consistently but has not noticed an improvement in symptoms, the doctor may increase the dosage or prescribe an alternative medication. It is important for patients to take their medication as directed by their doctor and to report any concerns or side effects to ensure optimal treatment outcomes.

An overdose can lead to cardiovascular and central nervous system toxicity
Bupropion, sold under the brand name Wellbutrin, is a medication used to treat major depressive disorder. It is also used to treat seasonal affective disorder, and smoking cessation, with several off-label uses, including treating anxiety and attention deficit/hyperactivity disorder.
In overdose, bupropion can lead to cardiovascular and central nervous system toxicity. Cardiovascular toxicity can include conduction delays resulting in widened QRS and QT intervals, dysrhythmias, or cardiogenic shock. QRS prolongation is due to the effect of gap junction intercellular communication rather than fast sodium channel blockade. QT prolongation is due to blockage of the rapid component of the delayed rectifier potassium current. Other cardiovascular effects include hypertension and hypotension.
The central nervous system effects of bupropion overdose include seizures, confusion, agitation, hallucination, and coma. Seizures are a well-defined risk in adults but are not common in children. Studies suggest that patients who ingest 4.5 to 9 grams of bupropion are at a greater risk of seizures, but doses as low as 600mg in adults have resulted in seizure activity. The risk of seizures with daily doses below 300 mg is estimated at 0.1% but increases to 0.4% with doses up to 450 mg daily.
The treatment for bupropion overdose includes supportive care and benzodiazepine during seizures. If patients come to the hospital shortly after taking the drug, activated carbon can be given. If a large ingestion of extended-release tablets occurs within the first 5 hours, whole bowel irrigation (WBI) can be considered.

Symptoms of overdose include seizures, hypertension, agitation, and GI issues
Bupropion is an antidepressant drug that is used to treat major depressive disorder, seasonal affective disorder, and smoking cessation. It is available in Canada as sustained-release (SR) and extended-release (XL) formulations, and in the US as immediate-release (IR) formulations.
An overdose of bupropion can lead to cardiovascular and central nervous system toxicity, resulting in seizures, hypertension, agitation, and GI issues. Seizures are a common symptom of bupropion overdose, occurring in up to 47% of cases. They can be single or multiple and may be delayed by up to 24 hours after ingestion. Agitation is another frequent symptom, and both agitation and seizures can be treated with IV benzodiazepines. Early intubation and sedation may be necessary for patients with multiple seizures or severe agitation.
Hypertension and tachycardia are also common symptoms of bupropion overdose. However, they rarely require treatment. Other possible symptoms include delirium, hyperreflexia, clonus, central nervous system depression, numbness, and dystonia. Large overdoses can result in QRS prolongation, ventricular dysrhythmias, and cardiac arrest. Electrocardiographic abnormalities, such as QT interval prolongation and QRS widening, have also been observed in cases of bupropion overdose.
The recommended course of action in the event of a bupropion overdose is to seek immediate medical attention by calling 911 or contacting a Poison Control center. For large overdoses (>2.5 g), aggressive GI decontamination should be considered. Activated charcoal may be useful several hours after ingestion to address GI issues.
