Antipsychotic medications work by blocking a certain type of dopamine receptor in the brain, but over time, this blockage can lead to an imbalance of dopamine and other neurochemicals. For some people, this can create abnormal signaling in the area of the brain that controls movement. If TD develops, the first step is to notify your doctor so medication can be safely adjusted, stopped, or switched. Medications and supplements may help ease symptoms. To prevent TD, your physician may prescribe a newer class of drugs with a decreased risk of developing the disorder.
