How do antihistamines work?Updated 4 months ago

Antihistamines work by inhibiting the binding of histamine to various receptors. 

In order for histamine to cause a histamine response, histamine must bind to a receptor.

When antihistamines are not used, the histamine is then free to bind to a receptor - causing a histamine response.

Thus, long-term use of an antihistamine is needed if one does not have sufficient ability to break down and eliminate histamine.

Antihistamines do nothing for the breakdown.

If one wants to support the healthy breakdown of histamine in the body, using supplements such as Histamine Nutrients and Histamine Digest can help.*
