Haloperidol Richter (Haloperidol)

Haloperidol Richter is indicated for the management of several psychiatric disorders where dopamine blockade is therapeutic. It is commonly prescribed in clinical practice for the following conditions:

• Schizophrenia, including acute exacerbations
• Acute psychotic episodes unrelated to schizophrenia
• Manic episodes associated with bipolar disorder
• Severe agitation that requires rapid control
• Tourette syndrome when other treatments are insufficient

Side effects of haloperidol can vary in frequency and severity. Patients should be aware of both common and potentially serious reactions.

Common

• Drowsiness or sedation
• Extrapyramidal symptoms such as tremor or rigidity
• Dry mouth
• Constipation
• Blurred vision
• Weight gain

Serious

• Neuroleptic malignant syndrome
• Tardive dyskinesia
• Severe hypotension
• Cardiac arrhythmias (QT prolongation)
• Elevated prolactin levels causing galactorrhea or menstrual disturbances

Before starting Haloperidol Richter, certain precautions should be considered to ensure safe use:

• Assess cardiovascular status, especially in patients with a history of arrhythmias or heart disease.
• Monitor for signs of extrapyramidal symptoms and tardive dyskinesia during prolonged therapy.
• Evaluate liver and kidney function, as impairment may affect drug clearance.
• Use cautiously in patients with a history of seizures or epilepsy.
• Discuss pregnancy and breastfeeding plans with a healthcare provider, as safety data are limited.
• Review any history of neuroleptic malignant syndrome before initiating treatment.

Haloperidol can interact with several other medications, influencing its efficacy and safety profile.

Avoid

• Other dopamine antagonists or antipsychotics, which may increase the risk of extrapyramidal symptoms.
• Medications that prolong the QT interval (e.g., certain antiarrhythmics, macrolide antibiotics).
• Strong CYP3A4 inhibitors such as ketoconazole, which can raise haloperidol plasma levels.

Use with caution

• CNS depressants (e.g., benzodiazepines, opioids) that may enhance sedation.
• Anticholinergic agents, which can mask early signs of extrapyramidal side effects.
• CYP2D6 substrates, as haloperidol may affect their metabolism.
• Alcohol, which can increase central nervous system depression.
