i’ve been trying to figure out what works better for my mast cell stuff, h1 or h2 antihistamines. imo been on cetirizine for ages, but recently added famotidine to the mix. anyone have experience with both? i’ve noticed that when i take them together, my flushing and hives are way more manageable, especially with aged or fermented foods. but i’m curious, does the order matter? should i be taking the h1 blocker first, or the h2? and how long after a trigger does it take for histamine levels to drop? been tracking my reactions in careclinic and it’s been helpful to see the weekly trend summary, but still trying to nail down the timing. anyone have insights?
What biomarker are you using to track histamine levels dropping?
