I read that both meds help symptoms such as tremors and rigidity. If such, why do docs prescribe Amantadine over Benadryl? Also, can Benadryl (as a sleep aid) be taken long term??And can both Amantadine and Benedryl be taken together?

Thanks.

benadryl can be used long term if under the direct supervision of a physician. if it it used for sleep on a nightly basis, once it is stopped, it can cause severe insomnia in some patients.
