Does anyone know of a safe antihistamine for kidney patients? I have been taking Mizolastine thinking there were not many side effects, but I was wrong. I have Bronchiectasis and found that the mizolastine did help with the wheezing and tightness. But aparently they are having trouble manufacturing them. My doctor prescribed cetrizine but on reading the information leaflet it says to take half if you have kidney problems. I am wondering if I should stop taking them completely and see what happens to my chest, or if there is a safter one on the market.
