Hello and hope you are doing well.
Normally, during the course of evolution from a baby to an adult, we develop a mechanism by which we desensitize ourselves to all the materials we are exposed to. But sometimes, the desensitization may not be perfect and we develop allergic reactions to those few substances. This is what happened in your case. On exposure to the allergen, an Immunologic (IgE) or a non-immunologic reaction is set in process, which ultimately releases histamine, which acts at the peripheral receptors, resulting in allergic reactions and rashes.
The aim of the therapy is identification and removal of trigger factor. It is the most important and the only effective long-term therapy. Maintain a diary and note down your symptoms, this will help to narrow down the search and you could avoid the allergens.
Local measures like ice packs and antipruritic lotions are helpful. Antihistamines block the histamine receptors and prevent histamine from acting and thus help in preventing rashes. Loratadine belongs to the class of medications called second-generation antihistamines. So, as long as you take the medication, you are unlikely to have the symptoms.
For now continue with the medication, long term you can plan to consult an allergy specialist for desensitization.
Hope this helped and do keep us posted.
The loratadine started working for me. Should I go to a allergy specialist soon or wait few days to see the action of loratadine?
Looks like you're allergic responses are causing rash, and Allergic Conjunctivitis. Consult an allergy specialist. First he may do a blood IgE levels to see if they are raised. Next, he will do skin testing. This test is painless, in which a very small amount of certain allergens are pricked into the surface of your skin. If you have allergies, just a little swelling will occur where the allergen was introduced. Reactions occur within about 15 minutes. If needed more sensitive intradermal tests will be used in which a small amount of allergen is injected within the skin. Based on this he may plan for immunotherapy.
