Allergic Reaction

An allergic reaction is the body’s way of responding to an “invader”. This triggers the immune system of the body which is helpful in fighting bacteria and toxins. The substance that causes an allergic reaction is called an allergen. Dust, pollen, plants, medication, and certain types of food are all example of allergens. The reaction could also be in one of many forms such as a small skin rash, itchy eyes, and even all over the body. It is very rare that deaths occur as a result of an allergic reaction. Penicillin is one of the medications which is known to cause allergies.

Allergies could also run in the family and be passed on from parent to child. Most people are aware of their allergy triggers and the corresponding allergic reaction. The best thing to do is to stay away from any of the substances that are known to cause allergies. Individuals with certain medical conditions may also be prone to some allergies; for instance, those with asthma or frequent infections of the nasal sinuses, ears or respiratory tract. A person with sensitive skin might also develop an allergic reaction to certain things. Different medications are prescribed depending upon the type of allergy and the kind of allergic reaction it produces.

Long-term allergies such as hay fever, or reactions to animal dander are prescribed long-term antihistamines which help control the symptoms without causing any drowsiness. Most have to be taken only once a day and their effect is felt the whole day. Nasal sprays are also prescribed if the nasal symptoms are not relieved by antihistamines. Allergy shots are also administered to some people who have persistent symptoms. These shots are usually given in a series over a certain period of time and the effectiveness of the treatment depends upon the individual.
