Why does Haldol make you feel so bad?

Haldol (haloperidol) is an antipsychotic medication that can cause side effects due to its effects on neurotransmitters in the brain, particularly dopamine. Common side effects include sedation, restlessness, and extrapyramidal symptoms such as tremors or stiffness. These reactions can contribute to feelings of discomfort or malaise. Additionally, the medication's potency and the dosage can influence how a person experiences side effects.
