How do antihistamine drugs affect the inflammatory immune response?

Experimental studies have documented that H1-antihistamines may affect several inflammatory events, including chemotaxis and the survival of eosinophils, the expression of adhesion molecules, and the release of chemokines and cytokines from different sources, thus highlighting the potential for a modulation of chronic …

The liver function is usually only slightly deranged, and returns to normal with substitution of another antihistamine or cessation of the therapy.

Do sedating antihistamines impair innate immune responses to bacterial infection?

Effects of antihistamines on innate immune responses to severe bacterial infection in mice Our findings indicate that sedating first-generation H1R antihistamines and H2R blockers might impair innate immune responses to bacteria and that these drugs should be used with caution in patients with severe bacterial infections.

Can antihistamines make you more susceptible to viral or bacterial infections?

Actually they can. C. Difficile is just one type of infection that can be precipitated by use of antihistamines, specifically H2 blockers. Perhaps by surpressing the production of gastric acid.
