I would say a big fat NO to that kind of drug at that age.
It's a disease manageable without medications of that kind of strength. It's neither progressive nor life-threatening. I would look into physical management of symptoms and mental management--a LOT can be done through the right kind of warm up, even within a single movement, and in training oneself to use the minimum effort to achieve the goal at hand--that prevents a LOT of freeze-ups.
