FAQ

Evidence-based clinical answers to common patient questions

💬 Haloperidol / Haldol) tablets/vaccines are the last resort for which disease?

This is an extremely powerful and widely used drug of the older generation (Typical antipsychotic) designed to control 'Schizophrenia' and severe psychosis! It is often used in hospitals (as an injection) to calm the patient down in a few minutes (Chemical Restraint) when a patient is going crazy and breaking into the hospital/property and attacking/killing others (Acute Agitation/Violence).

💬 How does this powerful drug (Haloperidol) reach the brain and make the patient numb like a stone?

One of the main reasons for the development of severe mental illness/violence is the excessive increase in the chemical 'Dopamine' in the brain! This drug blocks/closes the dopamine receptors (Strong D2 blockade) 100% as soon as it enters the brain. It eliminates the crazy thoughts in the mind and calms the patient to the point where he cannot even move his leg/arm.

💬 What are the most serious side effects of using haloperidol?

The side effects of this old drug are extremely serious! The biggest danger is 'Tardive Dyskinesia (EPS).' That means that when you drink this, you can experience severe discomfort such as uncontrollable shaking of the legs/hands, rolling of the eyes, and sticking out the tongue. The other most dangerous thing is a fatal condition called Neuroleptic Malignant Syndrome (NMS)! It causes the patient's body to become 100% stiff like wood, develop a high fever, and can lead to kidney failure and death!
