Hi. I'm new to the mail list and am hoping you can help. My Dad, 80 y.o. has Parkinsons for about 6 years. Was taking Sinamet and Elderpryl and doing very well with Parkinsons symptoms, but several times a day was experiencing severe low blood pressures on standing. (Florinef and salt helped for a while, but not much any more.) Tried Midodrine, but didn't help. Domperidone didn't help. PD specialist suggested dropping the Elderpryl. Now his Parkinsons symptoms are quite a bit worse, and still the low blood pressure. Any suggestions? Thank you for any help... Ruth
