In brief: Probably not

There have been many studies on the good effects of new generation antihistamines and up to this point, these medications have not been shown to develop "tolerance.
" in these clinical trials, the medications continued to work just as well with continued use. This is group data. However, very long term studies are not available. For a specific individual it's possible that a change may help.
