A member asked:

Im on 180mg x2 daily fexofenadine and cimetidine for mast cells but even this dose is not helping my hay fever-is normal considering it's a high dose?

A doctor has provided 1 answer

Allergies: Yes this is overdosing on fexofenadine (allegra). Consider going to an allergist to get further help.

A member asked:

My allergy medication is no longer working. How long should I wait after stopping daily 10mg Loratadine doses before switching to daily 180mg fexofenadine doses? I've read that don't want to mix anti-histimines, so is a wait period necessary?
