Hi there is anyone else on four x fexofenadine (or similar antihistamine) daily for chronic urticaria/angiodema? What have you done when you’ve still experienced a flare on that dose? Has your GP/consultant prescribed piriton or cetrizine on top of it? Also, if you’ve stopped taking your fexo and then it’s flared, how long has it taken for the 4 x fexo daily dose to kick in properly and prevent further flares?
