I Am Asking About Medication Reactions For My Husband's Medications.

I am asking about medication reactions for my husband's medications. He has been having (what I think) are dystonia like symptoms with facial grimacing, irratic arm and hand movements, verbal repetitive words speaking ie "baby,baby,baby" - all lasting less than a minute and then all of this brings on sweating for a few minutes. He has been worked up for seizures (negative) and no tumors found - EEG and Sleep Study - all negative.
Meds are Gabapentin, Mertazipine, Quetiapine, Tamsulosin, Levothyroxin, Naprosyn, Effexor
Only other symptoms has been the pin rolling of fingers ie?Parkinsons. Going back to Primary Internal Medicine next week for 6mo. checkup.
