Class Action Filed Against Makers of Budeprion XL

Teva Pharmaceutical Industries Ltd. (TEVA) and Impax Laboratories Inc (IPXL), are facing a class action lawsuit over allegations that Budeprion XL, their generic formulation of anti-depressant Wellbutrin XL, is less effective than Wellbutrin XL.

According to a report in today's Wall Street Journal, the suit, filed in California, states "It is scientifically proven that Budeprion XL contains an inferior delivery mechanism to that contained in Wellbutrin XL. That inferior delivery system results in a much more rapid, and potentially harmful, release of Budeprion XL's key ingredient to end-use consumers. The result is that Budeprion XL is less effective in treating depression and, indeed, is much more likely to cause certain dangerous side effects, as compared to Wellbutrin XL."

The allegations remain to be proved, and the US Food and Drug Administration (FDA) currently considers the drug to be safe, based on its evaluation of reports of side effects from users of generic Wellbutrin. However, the FDA may request a special clinical trial to further evaluate the generic formulation, although that has yet to be confirmed.

The plaintiffs in the lawsuit are seeking reimbursement of prescription costs paid for the generic drug, plus interest, and other, non-specified costs.

I now have extreme depression, fatigue, brain fog, memory loss, this medicine was prescribed to give me more energy and less depression/anger and I have been more depressed and frustrated since taking this medicine.

My depression increased markedly. I had unpredictable attacks of abdominal/back pain so severe it caused vomiting and diarrhea and I was nonfunctional several hours when it occurred. I also had painful stiffening of the joints to the point I could barely walk to the bathroom at night. I am a medical transcriptionist, and even though I am back on the original Wellbutrin, the stiffness still impairs my typing. I have had to go to a local emergency room once and urgent care centers twice because of the symptoms.

Name brand Wellbutrin was a life saver. It helped me quit smoking and I even quit caffiene. I was switched to the generic without any kind of notice and experienced a vast multitude of crippling side effects. The depression returned, along with suicidal idealization. I have lost friends, family and my job because of being on this pill. I might also still lose my apartment.

For over six months, I have suffered daily headaches, memory loss, anxiety, exhaustion and no energy.
