The Cons Of Allergy Shots

If you are considering allergy shots, there are some of the cons or negatives of the procedure that you should be familiar with:

• Allergy shots don’t work for all kinds of allergies. For instance, this treatment is not available for chronic hives (urticaria) or for food allergies.
• Also allergy shots are not for everyone. People with certain medical conditions are unable to use this therapy; such as those with high blood pressure.
• This treatment requires considerable commitment as it is a long term solution and benefits may be noted only after about 6 months to a year. And sometimes there may be a need to change therapy if it is seen not to work. For a person to develop full resistance to allergens, they may have to be in treatment for as long as 3 to 5 years.
• For 20% of people, allergy shots are not effective.
• Extra care needs to be taken when in therapy; HEPA filters and environmental precautions would have to be continued.
• Local reactions like redness, swelling and irritation to the injection site may be seen. Less commonly, there could also be systemic reactions such as nasal congestion, wheezing and throat swelling; very rarely anaphylaxis could also occur as a reaction to allergy shots.
