Also known as neuroleptics, they work by balancing brain chemicals like dopamine to reduce extreme thoughts and perceptions. These drugs aren’t for everyone—they’re meant for conditions like schizophrenia, bipolar disorder, and sometimes severe depression with psychotic features. But they’re not harmless. Many people don’t realize how common side effects like akathisia, a distressing inner restlessness often mistaken for anxiety or medication-induced psychosis, a rare but serious reaction where the drug itself triggers psychotic symptoms really are.

Antipsychotics can also cause weight gain, movement disorders, and heart rhythm issues. Some carry FDA boxed warnings, the strongest safety alerts the FDA can issue because of risks like sudden death in elderly patients with dementia.
