Physicians aren't sure why, but peanut allergies have been on the rise in recent years. Approximately 50 to 100 people die every year in extreme cases of allergic reactions to peanuts.
A drug that could prevent peanut reactions called TNX-901 is in its final stages of testing. Those with peanut allergies develop anti-peanut antibodies called IGE. Studies show the drug cleans the body of those peanut antibodies, so in the even there's an accidental ingestion, the person will have a less severe reaction.
"This new drug is not a vaccine because it doesn't change your immune system. It's given once a month and the cost may be $10,000 per year and the drug may not be available for a few years," said Dr. Satish Gupta, M.D.
Until the drug becomes available, allergists recommend patients keep an emergency self-injection handy in case they accidentally eat food with peanuts in it. The injection is available by prescription.
