Hello Everyone,
My 16 year old daughter has suspected mast cell overactivity and has been trying out various antihistamines (H1) and has been on Famotidine (H2) for a week. So far Clarityn/loratadine has been the best. She is now trying out Benadryl/acrivastine which she has been told to increase to three a day. I can't tell from the patient info if it contains ingredients other than lactose, and haven't found (so far) detailed info online. Or maybe my brain has shut down trying to get to grips with everything going on for her. She has had to drop down to one A level this year, and is supposed to restart her two A level years starting from next September, but if she doesn't get well enough we don't know how things will be. Doctors are looking into migraine, epilepsy, mast cell excitability. She was healthy until about two years ago when all sorts of symptoms started. Thank you very much.
