How Are Steroids Used To Treat Allergies


Steroids, also called corticosteroids, can lower swelling that comes with allergies. They prevent and treat sneezing and stuffy, runny, or itchy nose. They also help with red, itchy eyes. These drugs can be used for allergies, hay fever, and asthma. They come in pills, nose sprays, inhalers, eye drops, or skin creams. Steroids work very well, but must be taken regularly and often when you dont have symptoms. It may take 1-2 weeks for the medication to kick in fully.

    How Does Dr Kumra Customize Your Injection

    Allergy shots are a very precise science that involves a thorough test to determine to which;specific substances you have an allergic reaction. Dr. Kumra applies suspected allergens one by one to sections of your skin and then measures your allergic response. He can then formulate an allergy shot to those specifications.

    You receive these injections in two phases:

  • Buildup phase. Over a period of three to six months, receive injections with increasing amounts of the substance to which you are allergic. This reduces the chance of an adverse reaction to the shot itself.
  • Maintenance phase. Once the substance has built up in your system, you need injections less frequently to maintain your results.

    How Does Benadryl Help In Treating An Allergic Reaction

    Allergy is a reaction caused by our bodys immune system in defense to an external stimuli which the body sees as a potential danger. The main function of the immune system is to protect the body from harmful viruses and infection by producing certain antibodies. An allergic reaction is known to occur when the bodys immune system begins to fight other elements that are normally harmless. The body misunderstands that these harmless elements to be harmful and attacks them to cause an allergic overreaction. This reaction can manifest in various forms of allergies including rashes, itching of the eyes, runny nose, breathing problems and diarrhea to name a few.

    A person does not necessarily contract an allergic reaction the first time after coming in contact with the allergen or elements that trigger the allergy. The response is slowly created by the immune system and may be seen in the second or third interaction with the allergy causing agent.

    Besides dosing, there are some slight differences in how quickly or well the drugs work.;For example, while Claritin is effective for treating hay fever and hives, other antihistamines, such as;Zyrtec and;Allegra, work better and faster and last longer.

    Zyrtec and Allegra work quickly for the treatment of allergic rhinitis and hives, typically within less than an hour. On the other hand, studies show that Claritin takes many hours to start working.

    Studies show that Allegra is nearly as good as;Zyrtec;at treating hayfever. However, Zyrtec and its isomer Xyzal appear to be better medicines for the;treatment of hives.

    There are also some unexpected nuances associated with each of the antihistamines.

Juices such as orange juice or grapefruit juice;can decrease the absorption of Allegra;by nearly half.
