At its core, drug allergy is a negative reaction of the human body to any drugs or substances contained in taking medication. The main causes of drug allergy is an immune system that prevents the injected drug.

Also allergies can be caused due to incorrect dosage of the drug. The visible evidence of such allergies can be nasal allergy . allergic conjunctivitis , And a number of allergic reactions that have been stimulated by drugs.

Before the manifestation of allergy to any drug in the body is in the process sensitization Which is a primary contact of the immune system, and the injectable preparation, often causing no unpleasant consequences.

Only if the drug is not terminated, the dosage will manifest symptoms of allergy. Everything will depend only on whether the drug is administered. Different preparations may have different impact on the body. Here the approach is completely different, because each person has their own individual biological characteristics of which depend on the nature of the allergic reaction, and then, a drug allergy treatment will be most effective.

Many modern drugs can cause an allergic reaction. Moreover, it can manifest itself in very different ways. We know that drug allergies can appear in two cases.

The first is an allergic reaction caused by prolonged exposure to the drug received on the body, caused by the patient, which the drug is administered intramuscularly, or intravenously (just under the circumstances allergy manifests). In these cases, the more likely anaphylactic shock   patient. It is a very sharp deterioration in health indicators that someone injected an allergen, if at the time not to intervene, possibly fatal.

The second type is chronic allergies Very often it happens to people who do not take the drug, but regularly introduced to anyone, so one way or another, but they present a daily contact with the substance. This type is characteristic of people who work in the medical field, and they can get information on a non-permanent or total disability. Here it is more likely acute   and chronic urticaria . Urticaria is the formation blisters And the manifestation of itching and redness on the skin. Acute urticaria lasts for a couple of days to two weeks. Chronic can last for weeks, months, in very rare cases - years.

In addition to these allergy symptoms can appear angioedema   ( angioedema ). Its symptoms are similar to symptoms of hives, but differ in the depth of its manifestation. For example, if urticaria shown only on the skin surface, in the case of angioedema process occurs in depth, not only causing intolerable itching, but also causing swelling (thereby gets its name). It is manifested most often in areas of the skin, which has a loose retina (lips, eyelids, cheeks, etc.). Angioedema lasts a few hours (in rare cases, no more than 3 days). However, it is possible its development, and that it will be delayed for a few days, in this case required urgent hospitalization.

Prevention and treatment of drug allergy primarily means identifying allergen among substances that are entered, or with which contact occurs. In severe cases, it should be injected antibodies that the body normalize and stabilize the patient's condition.
