Neuroleptic Malignant Syndrome (NMS) is a rare but life-threatening reaction to antipsychotic drugs, including haloperidol, with a reported mortality rate of around 10-15%. This severe adverse effect is a critical concern for both patients and healthcare providers, requiring prompt recognition and treatment. While uncommon, the potential for **haloperidol to cause NMS** is a known risk associated with its use.

According to prescribing information and clinical data, muscle stiffness is a well-documented side effect associated with risperidone use. This can range from mild discomfort to severe, potentially life-threatening conditions like Neuroleptic Malignant Syndrome (NMS).

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.

Recent data suggest the incidence of Neuroleptic Malignant Syndrome (NMS) is approximately 0.01–0.02% in patients exposed to neuroleptics [1.2.1]. A critical question for clinicians and patients is: **Can haloperidol trigger NMS?** The answer is yes; it's a well-documented association [1.2.5, 1.2.6].

While neuroleptic malignant syndrome (NMS) is primarily associated with antipsychotic medications, a small number of recent case reports illustrate that abrupt benzodiazepine withdrawal can be a risk factor for developing NMS. This reveals a more complex relationship than a direct causal link, suggesting that the cessation of these drugs can alter the central nervous system in a way that predisposes vulnerable individuals to this rare and life-threatening condition.

Neuroleptic Malignant Syndrome (NMS) is a rare but life-threatening reaction to antipsychotic drugs, affecting a small percentage of patients who take these medications. This severe adverse reaction is characterized by profound muscle rigidity and hyperthermia, making the question of what muscle relaxant is used in NMS a critical concern for effective and rapid treatment.

Up to 10% of reported cases of Neuroleptic Malignant Syndrome (NMS) have been linked to the withdrawal of dopaminergic medications, not just antipsychotics. This includes the anti-parkinsonian drug amantadine, and its rapid cessation can precipitate a serious, and sometimes fatal, NMS-like reaction.

Although historically more associated with first-generation antipsychotics, published case reports confirm that quetiapine can cause neuroleptic malignant syndrome (NMS). This potentially fatal, idiosyncratic reaction requires immediate medical attention and remains a serious, albeit rare, risk for patients on this medication.

Neuroleptic Malignant Syndrome (NMS) is a life-threatening reaction most commonly triggered by antipsychotic medications. However, rare case reports suggest that sertraline, a selective serotonin reuptake inhibitor (SSRI), can also be implicated, either alone or in combination with other drugs. This raises crucial questions for patients and clinicians about this potential risk.

Despite the life-threatening nature of neuroleptic malignant syndrome (NMS), there is no single, specific antidote for NMS. Treatment is a rapid, multi-faceted medical response involving immediate medication withdrawal and intensive supportive care.
