My dermatologist put me on fexofenadine this year. I've used piriton, loratadine and cetirizine for long periods without any problems, but my reactions are breaking through and the doctor felt I needed something stronger.
In the last few weeks I've been getting random itchy weals. I thought at first insect bites, but they're definitely not. I've currently got 3 on each arm and one on my face. They last for several days.
Could they be a reaction to the fexofenadine?
I've not even been using it in large amounts recently. I know to taper my use, so I don't go from 4 daily to zero overnight.
