Primidone
"I was diagnosed with Benign Essential Tremor, a month ago...my Dr started me out on 12.5 mg of Primidone. I have increased my dosage every 3/4 days by 12.5 mg. I'm at 112.5mg and the tremors are still there. I also take a beta blocker as well. The side effects are flu like for me the day after I up my dosage. Then I have a "good day " & then the tremors start all over again. I cannot climax as a horrible side effect so I'm frustrated in more ways than one."
