Antihistamines: what effect do they have?

Do natural antihistamines exist?

The physical reaction to an allergy is usually very unpleasant. In these cases, anti-allergy medication is highly appreciated.

When a person suffering from allergies comes into contact with their personal allergen, such as pollen, food or an insect bite, the body releases the messenger substance histamine.

Histamine attaches itself to the histamine receptors in the cells, causing an allergic reaction in the form of a skin rash, itching, redness of the eyes, swelling, sneezing or a cold.

How antihistamines work

Anti-allergy drugs counteract this process, with antihistamines forming the main group. These are active substances that neutralise the effect of the body’s own histamine by blocking the receptors and thus preventing the onset of allergic symptoms. Antihistamines also alleviate the symptoms of an allergic reaction.

Antihistamines are used for the following allergies and diseases

  • Hay fever (pollen allergy)
  • House dust mite allergy
  • Animal allergy
  • Anaphylaxis (part of emergency kit)
  • Allergic conjunctivitis
  • Hives or nettle rash
