Osmolex ER is a prescription drug used to manage movement disorders related to problems with dopamine transmission in the central nervous system (CNS). Your doctor may prescribe it to treatParkinson's disease(PD) or drug-induced movement disorders calledExtrapyramidal symptoms(EPS). PD starts with small tremors and eventually progresses to more severe movement disorders that can include movements that are too fast or too slow. EPS are caused by the long-term usage of antipsychotic medications for psychiatric conditions like bipolar disorder and schizophrenia.
