Depending on the intensity of development of gravity flow, the amount of associated symptoms and complications are three severity of allergic reactions.
1 degree – light – localized. At this severity unpleasant symptoms are observed only in allergen exposure (as a bee sting – the bite, when exposed to household chemicals – in action). In the case of small severity of the allergic reaction in the patient may experience itchy skin, hives, fever up to 38 degrees, chills. Can also be observed tearing and difficulty in nasal breathing (swelling of the lining of the nose). In this case, possible to treat the injury site of allergen exposure and anti gel or cream relieves itching (e.g., fenistil-gel), and to give the patient a tablet fast antihistamine (e.g., Suprastinum). The intensity of an allergic reaction may increase for several hours.
2 degree – moderate – nonlocalized. Signs of allergy severity coincide with signs of mild, except for the localization of allergic reactions. They are not limited to the bite site, allergen exposure, and can be observed in all parts of the body. In addition, further may appear symptoms such as abdominal cramping, vomiting, diarrhea, asthma, throbbing headache and brief loss of consciousness.
3 degree – severe – anaphylactic shock. Reaction develops immediately, in a few seconds. May be accompanied by angioedema, severe throbbing headache or stomach pain (with the internal use of the allergen), long-term loss of consciousness (up to 2 hours). Typically, a consequence of drug allergy. The symptoms quickly joins edema of the larynx, blood pressure drops dramatically.
