pharmacogenomics
In cases where patients need to take more than 50 mg of Tetrabenazine per day it is required to do genetic test to determine if the patient is am extensive or poor metabolizer if CYP2D6 (as suggested by FDA). As poor metabolizers are much more susceptible to side effects it is important to increase the dose slowly and watch for any side effects that appear/intensify. For poor metabolizers the maximum dose per day of Tetrabenazine is 50 mg, on the other hand extensive and intermediate metabolizers can go as high as 100 mg per day.
