👩🏽‍⚕️ Additional questions (FAQs)

💬 Chlorpromazine Injection / Thorazine is a very powerful medicine used to treat which disease?

This is not an ordinary medicine! This is an injection of the oldest and most powerful (First-Generation Antipsychotic) emergency medicine used to immediately calm the patient and put him into a deep sleep (sedation) in cases of severe 'mental madness' (Severe Psychosis/Agitation) caused by schizophrenia, bipolar disorder, and drugs, when the patient is uncontrollably agitated, and is in extreme danger of harming others or himself/herself.

💬 When you are screaming/screaming like crazy, how does this injection (Chlorpromazine) help your brain heal/sleep?

Such strange things are seen/are extremely disturbing when the chemical 'Dopamine (Dopamine / D2)' in the brain overflows! This vaccine completely blocks/closes and locks all the 'Dopamine receptors' in the brain (Dopamine antagonist). In addition, it also turns off the machines in the 'Histamine (H1)' and 'Adrenaline (Alpha-1)' stages, so the patient becomes silent and sits still/sleeps in a few minutes.

💬 What are the potentially fatal side effects (Black Box Warnings) of this severe brain-damaging vaccine (Thorazine)?

The biggest danger is that if this is given to elderly people with dementia (Dementia-related psychosis), they can suddenly stop breathing and die (Increased mortality)! The other most dangerous thing is that this can cause the patient to fall into a coma due to 'Fatal Hypotension / Orthostatic'. Also, a severe neurological disease that makes it impossible to stay still, causing the limbs to shake like crazy and the neck/eyes to move (Extrapyramidal Symptoms / EPS / Tardive Dyskinesia) can definitely occur.
