Primidone
seizures
"I'm a 64 yr old male. I have essential tremor of the hands and neck/head. Until 5 yrs ago, it had gone undiagnosed or misdiagnosed for 45 years.  I've been taking Primidone for 2 months now.  I've recently increased the dosage to 100mg - 2 times a day. This is the only Essential Tremor drug I'm taking at this time. I've been on Inderal, Topiramate, Gabipentin, Carbodopa/Levadopa  and combinations. Recently Phenol injections into my neck muscles did more harm then good. Now, I can't even lift my arms above my shoulders. Here's hoping the primidone increase has some effect on my hands and head shakes. No side effects so far. I have not figured out why some days I have almost no tremor. Have tracked my diet, doesn't seem to be connected ?"
