When it comes to a drug like Raptiva, the risks most certainly outweigh the benefits. On its extensive list of side effects—including a brain damage disease called progressive multifocal leukoencephalopathy (PML) that is lethal—the drug company should add STRESS. I’ve talked with several people and one nurse in particular, who took this psoriasis drug for a few years before noticing any side effects. None of the psoriasis sufferers I spoke with have been diagnosed with PML, but not a day goes by that they aren’t fearful. And because the disease is rare, not much is known about it. Gloria, the nurse I spoke with, said that much of the medical community hasn’t put 2 and 2 together. In Gloria’s case she was hospitalized for neurological problems. ” The doctors couldn’t say that Raptiva was the direct cause, but they didn’t rule it out either,” she said.
