Peanut Patch Eases Allergies in Toddlers.

A wearable patch called Viaskin could prevent severe allergic reactions in toddlers with peanut allergies, according to the results of a promising clinical trial. After wearing the experimental patch around 22 hours a day for a year, 67% of the children were able to tolerate 300 to 1,000 milligrams of peanut protein. The patch contains a small dose of peanut protein equal to about 1/1,000th of a peanut kernel. The Viaskin trial is the first to study a non-oral option for children under 4 with peanut allergies. The patch could eliminate some of the barriers to access for parents and children with peanut allergies.
