The active ingredient of this product group, to which the Fenistil® gel, which is probably best known under the name Fenistil®, belongs, is called Dimetinden and is a drug from the group of H1 antihistamines.

Allergic reaction come about because the body is actually a harmless foreign body, such as Animal hair or Bee pollen, classified as dangerous and that Defense system consequently shows a hypersensitivity reaction. In order to combat the apparently harmful substance, the organism reacts by producing a large number of messenger substances that are supposed to protect it. This is also included Tissue hormone histamineleading to an inflammatory reaction. This makes histamine one of the main triggers of the symptoms that arise from an allergy.

This means that this substance blocks the H1 receptors that histamine normally docks with in order to be effective. The body continues to release histamine as always, but since the binding sites for it are now occupied, the body can no longer react as usual. The inflammatory reaction is consequently attenuated or does not occur (Fenistil®). Because this mechanism not only takes place in the body tissue, but also in the brain, and there the action of messenger substances that are similar to histamine is inhibited, some of the side effects such as fatigue or Dry mouth to explain.
