Watson pharmaceuticals symptoms and conditions

My teenage daughter was taking generic Wellbutrin (manufactured by Watson pharmaceuticals) 150 mg. daily for about 3 weeks or so and started having serious hair loss on the top of her head. The prescribing psychiatrist told her to stop the medication and after about 2 weeks, the hair loss has stopped almost completely. I have read a number of blogs including this one that indicate that hair loss is a side effect yet the Wellbutrin trials only listed hair loss as a side effect for less than 1% of patients. Given the U.S. Supreme court ruling today that says that even if the FDA has approved a medication, a pharmaceutical company is still responsible for fully reporting side effects and can in fact be sued in individual states if they do not provide sufficient warning, I would be interested in hearing ideas of how we can put more pressure on the manufacturers of Wellbutrin and its generic equivalent so that they give better warning of this side effect.
