nothing. for lactose intolerance you can take a lactose pill. lactose intolerance is the gut's incapability to deal with milk sugar. this should never be confused with a true and possibly deadly allergy. food allergy reactions can be serious. if you have mild allergy-induced asthma, your doctor might be able to put you on an asthma maintenance medication that would help control the effects of the allergy. Singulair is one that comes in pill form.
