"i started abilify because my bipolar disorder drug cocktail became less effective. abilify was new on the market. it lifted my mood considerably, i felt great. and without any bad side effects. i thought.  after about 6 weeks i developed hand tremor. it got worse. my psychopharmacologist sent me to a neurologist who began treating me for a kind of tremor that&#039;s inherited. he did not believe it was due to abilify- which now has a side effect listed as &quot;muscle movements that could become permanent.&quot; naturally i stopped taking abilify. so either the neurologist is right, and abilify activated the tremor or i developed the permanent muscle movement side effect. either way, i now have to take an anti-tremor drug."
