There are a number of nonpharmacologic options she could try. I recommend hypoallergenic or anti allergen pillow and mattress covers and a small airfilter for her bedroom as first line options. If she has carpets or throw rugs, a vacuum cleaner with a HEPA filter is a good option as well. If she does get hives from time to time an over the counter medicine like zyrtec (cetirizine) is usually very effective.
