Although there are number of different treatments available for allergies, most if not all only treat the symptoms and not the root cause of the problem. Well-known antihistamines such as Benadryl a.k.a. diphenhydramine, Claritin also called loratadine together with decongestant sprays such as Nasonex, are available by prescription or over the counter and do a good job in providing relief for allergy sufferers. Allergic reactions are ultimately caused by an overactive immune system and a treatment known as allergy immunotherapy attempts to offer a longer-term solution by changing how the immune system responds to various allergens. It is, in effect, a form of vaccination better known as allergy shots

New allergy research is continually being carried out in an effort to discover ways to combat and control allergy symptoms, particularly for those who suffer from the severity of one or more allergies. Even folks who experience mild types of allergies find that they can disrupt their life and make it difficult for them to perform their usual daily activities.
