The study concluded certain people who use PPA are 15 times as likely to suffer a hemorrhagic stroke as nonusers. First-time users of the ingredient are three times as likely to suffer a stroke. Now that these numbers have been verified by scientific data the risks of using phenylpropanolamine clearly outweigh the benefits. Additionally these conclusions raise concerns over these companies continuing marketing of this product for so long without adequate testing. The Yale University study showed who are the highest risk people from use of PPA products are women aged 18 to 49.
Men are also at risk.
Many products now advertise that they are PPA free. Most of the PPA products have been pulled from the market. I have used products that contain phenylpropanolamine. In general, the increased risk of hemorrhagic stroke occurs among women aged 18 to 49 who used weight control products. There is also a risk in using PPA products for nasal decongestion.
