Description
Haldol (Haloperidol) is a medication commonly prescribed to treat mental health disorders, including schizophrenia, acute psychosis, and bipolar disorder. It belongs to a class of drugs known as antipsychotics, which work by blocking the effects of dopamine, a neurotransmitter in the brain.
Schizophrenia is a chronic mental illness characterized by disturbances in thinking, emotions, and behavior. Symptoms can include hallucinations, delusions, disorganized thinking, and a lack of motivation or social withdrawal. Haldol helps to alleviate these symptoms and improve overall functioning.
Haldol works by blocking dopamine receptors in the brain, which helps to restore the balance of chemicals and reduce psychotic symptoms. It is available in various formulations, including oral tablets, injectable solutions, and long-acting depot injections for maintenance therapy.
