He sneezes and blows his nose constantly, but especially at night. My Mom is recovering from surgery and not getting much rest here lately. Dad has problems with dementia and his heart and is taking several other medications. I would like to find the right allergy med that will work for him. I was using Allegra, but it doesn't appear to be working any more. I next thought Benadryl, but it is highly un-recommended for seniors. I want to know what other options I have.
