Severe reactions occur rapidly, usually immediately after the patient eats, is bitten by an insect, or takes medication; Treat a severe allergic reaction as a medical emergency and follow primary care procedures

Patients having severe allergic reactions may have hives, wheezing, chest tightness, stomach pain and complain of nausea, difficulty breathing and swallowing sometimes due to swollen throat tissue, their blood pressure may drop leading to dizziness and fainting

Mild allergic reactions include sneezing, itchy eyes, runny nose and skin rashes, they are not usually life threatening and usually controlled by antihistamines

Anaphylactic shock is having a severe allergic reaction that often results in breathing difficulties for the sufferer. The person may also develop a weak thready pulse accompanied with low blood pressure and altered levels of consciousness. A doctor may prescribe an auto-injector EpiPen® when a person is identified as being at risk of anaphylactic shock.
