Desensitization, which is a slow process of eating tiny amounts of milk, until the body is able to tolerate more significant exposure, results in reduced symptoms or even remission of the allergy in some people and is being explored for milk allergy.[8] This is called oral immunotherapy. Sublingual immunotherapy may be somewhat safer, but less effective.[9] A 2014 meta-analysis found desensitization to be relatively safe and effective but found that further study was needed to understand the overall immune response to it, and questions remain open about duration of the densensitization.[1][10]
