As Lamar Odom fights for his life after being found unconscious in a Nevada brothel, officals with the Food and Drug Administration are warning about the herbal Viagra he was taking. They say the herbal supplements are wildly different from prescription Viagra, and if you have any, you should throw it away.

Herbal Viagra isn't regulated by the FDA, and can be bought pretty much anywhere without a prescription. Because there is no federal oversight on the manufacturers of the supplements, they can put whatever they want into the product. FDA officials say they have found ingredients in the herbal supplements that could cause a dangerous drop in blood pressure, especially if the user takes nitrate medications for heart problems.

Odom had been taking Reload herbal supplements from the brothel's shop. Officials say he also tested positive for other substances including cocaine.
