Allergic reaction to preservatives
Many manufacturers often add preservative chemicals such as sodium benzoate to perishable goods. Most cases of food allergies can occur from a reaction to these chemicals. Eczema, hives, nausea, vomiting and a metallic taste are the usual symptoms of a food allergy.
There are also cosmetic products that contain preservatives in order to prolong their shelf lives. Highly sensitive individuals can end up with symptoms from direct exposure such as swelling or rash. Based on studies conducted, it was discovered that those who have preservative allergy have increased throughout the years since many companies have introduced new chemicals in their products.
Diagnosing an allergy
If you suspect that an individual has preservative allergy, allergy testing must be carried out in order to confirm if there is indeed an allergy. The doctor will perform tests in order to determine the allergy. In most cases, skin testing is carried out in which a small amount of the allergen is introduced into the skin. Irritation or swelling at the site indicates an allergy. In case a skin test poses as a safety risk, blood testing can be performed since it can also provide consistent outcomes but the results will take some time.
How to prevent and manage allergies
It is important to bear in mind that preventing an allergy is possible by avoiding the offending substance. In some circumstances, this avoidance is impossible. There are over-the-counter medications that are highly effective in managing the minor allergy symptoms. As for severe symptoms, it would require immunotherapy which involves a series of injections to control the immune system. The doctor will recommend the ideal course of action for managing the symptoms of an allergic reaction. If the individual is prone to severe allergic reactions, the doctor will prescribe an epinephrine shot that the individual must bring at all times.
