Medical Cases Of Bupropion Overdose

A report published in the Balkan Medical Journal explains a scenario where two patients were analyzed following a case of bupropion, Wellbutrin generic, overdose.
The first patient was 19 years old female. She took a total of 30 tablets, each containing 150mg of bupropion. The individual was taken to an emergency department immediately. While vital signs measured through the Glasgow Coma Score were considered “good,” the woman experienced two seizures. Each lasted up to 10 seconds. The seizures were only present approximately six hours following the individual’s admission to the hospital.
In another case, there was a female patient, aged 20, taken to an emergency department after taking 15 Wellbutrin XL  150mg tablets. While the individual’s vital signs were stable at the time of admission to the emergency department, the woman experienced a tonic-clonic seizure shortly after the medical staff on duty hospitalized her. The seizure lasted for 30 seconds.

  • There can be an increase in the individual’s pulse
  • A pounding heartbeat may develop
  • A person may begin to experience erratic movements of their eyes

The individual will be asked some questions by the staff on duty during the call to 911, as this helps the staff dispatch the right medical professionals and ensure appropriate equipment and other medical items are taken to the patient’s location.

  • If the individual is unable to make the call themselves, someone in a close perimeter should do that as soon as possible.
  • It is crucial that a patient tells their location to the emergency services to ensure a faster response time.
  • The emergency dispatcher can also ask a person when they took the pills and how much.
  • This information may help the dispatcher determine how much of bupropion may still be circulating in the patient’s body, based on half-life of bupropion.

Once all details have been provided, it is always a good idea for a person to remain on the phone with the medical staff. These individuals are trained to provide patients in need of medical services with the guidance and ensure they understand what to expect and provide any details that should be given to the paramedics once they arrive. While awaiting paramedics to arrive, it is advised that a person tries to remain as calm as possible.

Treating Wellbutrin Overdose

Following a pickup by the paramedics, a person will be taken to an emergency department for prompt treatment. The first step is for a physician to assess the person. A detailed report on the person will be required. The physician might ask the person if they took Wellbutrin XL 300 mg or another dose or formulation of bupropion, as well as how many pills they took.

Once an assessment has been conducted, detoxification would be required. At this point, it is not important why the person has overdosed on Wellbutrin – whether they accidentally overdosed or tried to get high on bupropion led to only one scenario – getting the drug out of the individual’s body is critical. The most common detoxification procedure would be an oral administration of activated charcoal.

The treatment process after these steps have been conducted depends on the physician’s findings and the vitals of the person who has been admitted.

Dangers Of Overdosing On Wellbutrin

Wellbutrin might be an effective drug for treating depression, or smoking cessation, but too much of bupropion can be life-threatening. Abuse of this medication is also possible.

The person eventually takes more of the medication, which can ultimately contribute to an overdose.
Professional medical treatment is needed to help a person reduce the risk of the life-threatening complications that may occur following a Bupropion overdose.
Individuals abusing Wellbutrin are at an elevated risk, but with a thoroughly planned rehabilitation program, a person would be able to stop using the medication without experiencing significant adverse effects or withdrawal symptoms.
