I'm hoping someone here can help me. I've been taking anti-histamines for abou 4 months now for what my dermatologist calls general over-active immune system which causes itching and hives. I've been on Claritin, Aerius, Benadryl and now Reactine (Zyrtec).
I've noticed my hair thinning during this time. Does anyone know if this is a side effect of antihistamines? If it is, is there anything I can do to stop it without going off the meds? I'm really freaked out over the hair loss. Maybe I should just quit the meds and hope for the best?
