I have had a allergic reaction (hives). im breakin out on my hands and vagina.(spread there last time) can it be an allergic reaction?

May be: However, you can get hives without having an allergic reaction to something. If you get any trouble breathing or swelling in your tongue, you need to call 911. Otherwise, Loratadine or Diphenhydramine can really help. Sometimes adding ranitidine can help as well. You can see a doctor about it to make sure you don't have allergies. (hives without allergies is called idiopathic urticaria).

Visit allergist: A physician should perform a physical exam and review your symptoms history and any medications you might be taking. They can recommend an aggressive antihistamine regimen including h1 and h2 antihistamines and might include a lt rc blocker such as singulair (montelukast).
