Affecting an estimated 500,000 people in the U.S., tardive dyskinesia (TD) is a significant concern [1.9.2]. This raises the critical question for many patients and clinicians: **Does gabapentin cause tardive dyskinesia?** While not a classic trigger, the answer is nuanced.

While the incidence of Neuroleptic Malignant Syndrome (NMS) has decreased to about 0.01% to 0.02% of patients taking neuroleptics, the question remains: **can atypical antipsychotics cause NMS?** Yes, virtually all atypical antipsychotics have been associated with this life-threatening reaction.

Though rare, with an incidence estimated between 0.01% and 0.03% among patients taking antipsychotics, neuroleptic malignant syndrome (NMS) is a life-threatening medical emergency. Understanding which factors increase the risk for neuroleptic malignant syndrome (NMS) is crucial for both healthcare providers and patients to facilitate prompt recognition and management.

In chronic psychiatric patient populations, the prevalence of drug-induced parkinsonism, a condition marked by muscle stiffness, can range from 17% to 72% [1.3.1]. Yes, **can antipsychotics cause muscle stiffness** is a significant concern, primarily through a group of side effects known as extrapyramidal symptoms (EPS) [1.2.1, 1.2.3].

An estimated 0.02 to 3 percent of patients taking antipsychotic agents may develop neuroleptic malignant syndrome (NMS). When this occurs, physicians often **give lorazepam for neuroleptic malignant syndrome** as a first-line intervention to help manage severe symptoms, including muscle rigidity and agitation.

According to pharmacological data, droperidol's potent dopamine D2 antagonism is the primary mechanism behind its ability to cause extrapyramidal side effects. As a butyrophenone, it shares this risk with other antipsychotic medications, though the incidence is often dose-dependent.

The prevalence of acute dystonic reactions (ADRs) can range from 3% to 10% for patients on certain medications, and may be as high as 51.2% with high-potency antipsychotics [1.4.6]. Understanding what drugs cause dystonic reactions is crucial for patient safety and awareness.

Droperidol is a powerful antiemetic and antipsychotic medication that can cause acute extrapyramidal side effects, including distressing dystonic reactions. This occurs due to its potent dopamine-blocking action in the brain's motor control centers.

While most people are familiar with their use for psychiatric conditions, certain antipsychotic medications are also powerful tools against severe nausea and vomiting. Prochlorperazine, a well-known example, has been utilized as an antiemetic since its introduction, leveraging its ability to target specific brain receptors. Understanding which antipsychotic is used for anti-nausea reveals an important therapeutic overlap in pharmacology.

Based on data from 2013 to 2018, approximately 1.6% of adults in the U.S. use antipsychotic medications, a major class of drugs that can deplete dopamine [1.10.1]. Understanding **what drugs deplete dopamine** is crucial for recognizing potential side effects and health implications.
