Psychiatric medications are psychoactive drugs that act on chemical messengers in our body called neurotransmitters and hormones.  Neurotransmitters travel across synapses, while hormones travel through the circulatory system from glands to target organs.
In the U.S., prescription and over-the-counter medications are regulated and must be approved by the Food and Drug Administration (FDA) to be marketed.
