He has done quite well with Allegra for seasonal allergies, and even better
with Zyrtec. Zyrtec is OTC but allegra is not. Both are well tolerated
with Risperdal. Benaadryl is not good with Risperdal. My son, age 17, is zonked out when he takes both. He basically is out like a light and doesn't wake up in the morning (until about 12 hours later) the few times he has taken it. Not good at all. Claritin does not work for him either, nor anyone in my family.
