cetirizine + famotidine

A combination therapy that blocks both histamine-1 (H1) and histamine-2 (H2) receptors. Cetirizine is an antihistamine that primarily affects the respiratory system and skin by blocking H1 receptors, while famotidine blocks gastric H2 receptors to decrease stomach acid production. This dual-histamine receptor blockade has been studied for various conditions including COVID-19, interstitial cystitis/bladder pain syndrome, and allergic conditions. The combination has shown beneficial effects in reducing inflammation and cytokine release.
