Abuse of antiparkinsonism drugs. Feigning of extrapyramidal symptoms to obtain trihexyphenidyl

Abstract

Many physicians may be unaware of the abuse potential of antiparkinsonism medications. A case report suggests that the deliberate abuse of these drugs may be considerably more widespread than has been hitherto believed. Patients may feign extrapyramidal symptoms to obtain antiparkinsonism agents. Physicians should exercise greater caution when prescribing these drugs.
