Hello, This shaking can be due to mainly two drugs- licab and aripiprazole. You must talk to your doctor about the side efects. Had i been treating you I would have stopped both of these & shifted you on some safer anti psychotic / or simply increased the dose of quitipin. Even there is usually no need of giving so many drugs in one case, that too in such low doses. Looks like you have bipolar disorder and are put on three mood stabilizer instead of one- quitipin, lithium & topaz-- all in low and insufficinet doses. If you are so prone to CNS side efects, like tremors, I would have preffered oxcarbazepine as a mood stabilizer. So, the tremors/ shaking are side efcts o these drugs, and treatment definitely needs revision to save one from long term damage and daily embarrasment. Good luck. Dr. Manisha Gopal MD psychiatry
