Wellbutrin, known generically as bupropion, is a medication commonly prescribed for major depressive disorder, seasonal affective disorder, and smoking cessation. Taking more than directed can lead to an overdose. Recognizing the signs of an overdose and understanding immediate actions are critical for a favorable outcome.
Recognizing an Overdose
An overdose of Wellbutrin can manifest through symptoms affecting the nervous and cardiovascular systems. Neurological signs include agitation, confusion, hallucinations, and tremors. Seizures are a significant concern, sometimes delayed in onset, particularly with extended-release formulations.
Cardiovascular effects often present as a rapid heart rate (tachycardia) and elevated blood pressure. Severe overdoses can cause cardiac rhythm disturbances. Other general symptoms might include nausea, vomiting, dizziness, drowsiness, or fever. The severity and specific symptoms can vary based on the amount of medication ingested and individual patient factors.
Immediate Emergency Steps
If a Wellbutrin overdose is suspected, contact emergency services immediately by dialing 911 or the local emergency number. It is also helpful to contact a regional poison control center, as they can provide immediate guidance. Provide emergency responders with information: approximate amount taken, time of ingestion, other substances involved, and medical history.
Remain with the person until help arrives to ensure their safety and provide supportive care. If a seizure occurs, gently guide them to the floor and clear the area of any objects that could cause injury. Cushion their head with something soft, and loosen any tight clothing. Do not attempt to restrain them or put anything in their mouth during a seizure. After the seizure, help them roll onto their side if unconscious to prevent choking on vomit or saliva.
Professional Medical Interventions
Upon arrival at a medical facility, healthcare professionals prioritize stabilizing the patient by assessing and managing their airway, breathing, and circulation. Continuous monitoring of vital signs and cardiac activity through an electrocardiogram is standard procedure. This allows medical staff to detect and address any heart rhythm abnormalities that may arise from the overdose.
Decontamination methods may be used if the ingestion was recent (typically within one hour) and the patient is alert enough to protect their airway. Activated charcoal can be administered to help reduce the absorption of the drug from the gastrointestinal tract. For very large ingestions, especially of extended-release formulations, whole bowel irrigation might be considered to flush the medication from the system.
There is no specific antidote for a Wellbutrin overdose; therefore, treatment primarily focuses on supportive care for the symptoms. Seizures are managed with medications, with benzodiazepines being the first-line treatment choice. If seizures persist despite benzodiazepine administration, other medications like barbiturates or propofol may be used.
Medications like phenytoin are generally avoided for bupropion-induced seizures, as they are less effective and may worsen cardiac toxicity. Cardiovascular complications, such as QRS widening, may be treated with intravenous sodium bicarbonate. In rare, severe cases of cardiac toxicity that do not respond to other treatments, intravenous lipid emulsion therapy may be considered.
Recovery and Ongoing Medical Management
After the acute phase of a Wellbutrin overdose is managed, continued hospital observation is necessary. Patients who ingested extended-release formulations require monitoring for at least 24 hours due to the risk of delayed-onset seizures. Medical professionals will also assess for any potential complications that may have arisen during the acute phase, such as kidney injury, which can occur if severe seizures led to muscle breakdown.
Addressing the underlying reasons for the overdose is a crucial component of ongoing management. Patients may receive referrals for mental health support, including psychiatric evaluation and psychotherapy, to address depression, suicidal thoughts, or other mental health conditions. For overdoses related to substance abuse, treatment programs may be recommended. Follow-up medical appointments are important to ensure complete recovery and to adjust medication regimens if needed.
