A word, or two, of caution... My wife was hospitalized last week due to a chronic overdose of Wellbutrin SR. She's been on it for over a year and when she takes the correct dose it works for her. But during a recent office visit, her LNP accidentally wrote the script down incorrectly on the pad. Instead of the normal 2 100 mg tabs twice a day, she wrote down 2 200 mg tabs twice daily. This is TWICE the maximum daily dosage per the PDR. The pharmacy, a national chain that trumpets their computer system on TV ads for catching bad scripts and potential harmful interactions, was all too happy to dispense it. My wife noticed the pills looked different, but double-checked the label for the instructions: "Take 2 tablets - twice daily."
Let me pause for a second and acknowledge that most, if not all, Rx drugs have health consequences if overused. But the ER docs that we later encountered said that Wellbutrin has a smaller margin for error that other anti-depressants.
She started unknowingly OD'ing herself two Sunday's ago. She said she was rather tired for the next couple of days, but she attributed that to the OTC cough syrup she was taking for a cough she developed. She had been taking the OD for four days when she went critical at work. She couldn't do simple math, she didn't feel right, and she'd read things but couldn't comprehend some sentences. Her co-workers said she was pale and her eyes were red.
Thankfully, she had to presence of mind to think that the Wellbutrin had something to do with it. She called her doctor's office and the pharmacy. A co-worker drove her to the doctor's office. In the meantime the doctor and pharmacist realized the error. When she arrived at the doctor's office her resting pulse rate was over 140! The main risk of OD'ing on Wellbutrin is Grand Mal seizures.... which they thought she might have at any moment (throw in a stroke or cardiac arrest too for fun!) They called the ambulance and she was off to the ER.
She spent the night in the ER. Per the Poison Control Center, there wasn't much they could do other than give her activated charcoal to drink. She started to come "down" the next morning, but they had to put her on heart meds lower her still elevated heart rate (then around 100). She was discharged later that morning and has been off work for a week now. She's been going through cold-turkey withdrawal (slept around 18 hours the first couple of days) and then a slow build-up of going back on the Wellburtin SR.
The aftermath... All indications are she'll have a full recovery. They said if she had continued with the OD for a couple more days there could have been permanent damage to her health... or death. The LNP and doctor were horrified at the error. They have been great. They've apologized, told us they won't blame us if we left the practice, etc. etc. Someone from the hospital's Rick Management office (they also own the office where the doctor practices) came to the ER about two hours after she was admitted and said the error was theirs and they would cover all expenses, including lost time at work, child care, etc. etc. I was expecting them to ask us to sign a waiver excluding them from further liability in exchange, but no such request was made. Theres no indication that this represents a pattern of problems with the LNP or doctor.
The pharmacy was another story. It was clear from my layman's reading of the PDR for Wellbutrin SR that there should have been a red flag at the pharmacy when the bad script was presented. I took a photocopy of the DPR entry and took it to the pharmacy. The pharmacist on-duty (not the one that filled the script) was doing a major CYA. She was sorry that my wife was sickened, but she said doctors prescribe off-label (deviate from FDA approved labeling) "all the time" and they "were just doing what the doctor ordered". I know that State Board of Pharmacy regulations prohibit the dispensing of any prescription that the pharmacist has reason to believe that such prescription COULD cause harm to the patient. As terms of their license, they are bound to double-check or question prescriptions that dont look right. So I said I wanted to know if the dispensing pharmacist had called to verify the script before filling it.
We've talked to about 10 health care professionals we know about the case, and their initial reactions were all the same... They'd drop their jaws and say "She was talking HOW MUCH per day!?!?!?" One friend, who's a nurse, asked a 3rd year pharmacy student about what they'd do if presented with a script for 800 mg of Wellburtin SR a day. The student immediately responded "I wouldn't fill it.... the maximum dose of that is 400 mg per day!"
Four days later I still hadn't heard back from the pharmacy. So I called again. Later in the day the district pharmacy manager called me back. He, for the first time, said they should not have filled the prescription. He also said their computer system should have flagged the script as questionable. He tested it with the same drug and dosage to be sure. He said the pharmacist on-duty at the time would had to have OVERRIDDEN the warning to dispense the drug. He said hed investigate what happened and get back to me. In the meantime I have an Allegation form from the state on my desk with their name on it!
