What special precautions should I follow?

• Do not drive, operate heavy machinery, or do other dangerous activities until you know how Latuda affects you. Latuda may make you drowsy.

• Do not exercise too much.
• In hot weather, stay inside in a cool place if possible.
• Stay out of the sun.
• Do not wear too much clothing or heavy clothing.
• Drink plenty of water.
• Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Latuda is not approved for the treatment of patients with dementia-related psychosis.
• Increased incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) may oocur with Latuda. Latuda is not approved for the treatment of patients with dementia-related psychosis.
• A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with administration of antipsychotic drugs, including Latuda. If NMS is suspected, immediately discontinue Latuda and provide intensive symptomatic treatment and monitoring.
• Tardive dyskinesia is a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements that can develop in patients treated with antipsychotic drugs. If signs and symptoms of tardive dyskinesia appear in a patient on Latuda, drug discontinuation should be considered.
• Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk. Monitor for hyperglycemia/diabetes mellitus, dyslipidemia and weight gain
• Leukopenia/neutropenia has been reported during treatment with antipsychotic agents. Perform complete blood counts (CBC) in patients with a pre-existing low white blood cell count (WBC) or a history of leukopenia or neutropenia. Consider discontinuing Latuda if a clinically significant decline in WBC occurs in the absence of other causative factors.
• Latuda may cause orthostatic hypotension and syncope, perhaps due to its α1-adrenergic receptor antagonism. Monitor heart rate and blood pressure and warn patients with known cardiovascular or cerebrovascular disease, and risk of dehydration or syncope.
