They need to beassessed clinically and supported with blood investigations, CT, MRI brain and EMG whether they are idiopatic or essential, related with
alcohol abuse, excess thyroid hormone, liver failure, any trauma to brain, certain medications like amphetamines and steroids, etc. management would differ for each type of tremor and hence I cannot prescribe you one drug which may help without clinical evaluation. I suggest that you consult a neurologist for the same. Wishing you all the best.
