My allergy dr just prescribed me a drug called aterax, as required though evenings only,
for my
allergy issues. She also told me that it might help with some of the weird sensory stuff.
Anyway, I researched this drug - it is one of the first antihistamines, and seems to be very safe. Aside from antiallergy, it's effects include sedation, antianxiety, anti-nausea (I sure need that at the moment), some effect on pain relief, and it also enhances the effects of other pain killers.
