My husband has recently been put on this drug (he is being treated for hallucinations and does have vascular dementia) He has started shaking and jerking this last 2 weeks (has taken haloperidol for about 4 weeks in total). His mobility has become seriously impaired and is now bent over on the occasions he does walk. Can this be the haloperiodol? He is also being given Trazadone. I understand that today the doctor has removed the haloperidol from his daily drug regime.
