Can prozac, klonopin, ziprasidone or vyvanse cause shaky hands?

I would go to Drugs.com and read side effects of each and all other meds and OTC stuff you take. Then. I would search for interactions of these with each other. Then discuss with your team.

Yes, one or more may on occasion result in tremors of hands and arms when held upright. But NOT shaking at rest, or while doing a coordinated task. As has been recommended, obtain opinions from your involved clinicians to decide the next steps.
