Q
Period of time to trial antihistamine

I have chronic hives and appeared to have 5 good days with fewer hives and minimal itch with 2 x fexo in morning, 1x montelukast and 2 x Clarex (desloratadine) at night (usage for a period of 2 weeks). Thereafter i swopped to Levocetirizine (allerway) and now the hives appear to be many more with more itchiness. How long does it take for our body to adjust to an antihistamine?shoudl we do a trial of 2 weeks? Do some generally do better with one over the other? Should i purchase more Clarex instead

Some antihistamines suit different individuals better, so it makes sense to try different ones and find what suits you. Generally speaking, one needs to take high dosages of antihistamines (up to 4 times the normal dose) under your doctor's supervision on a regular daily basis.
