We report a 71-year-old woman with tactile hallucinations induced by trihexyphenidyl. Six and a half months after starting trihexyphenidyl, this patient with Parkinson's disease complained of tactile hallucinations, mainly on her feet, at night while in bed. Four days after stopping the medication, the sensations disappeared. Although tactile hallucinations induced by trihexyphenidyl are rare, it should be noted that the condition can be induced by anti-Parkinson's disease drugs.
