Tardive dyskinesia (TD) is a movement disorder. It's caused by using medicines called antipsychotics, often for a long time. Doctors use these medicines to treat mental health conditions such as schizophrenia.
Some people can take these medicines without getting TD. But for those people who do get it, the symptoms can cause distress.
TD causes a person to repeat the same movement over and over without being able to stop. If you have TD, you might have symptoms such as:
- Repeated chewing motions.
- Smacking your lips.
- Thrusting your tongue out of your mouth.
- Twitching your tongue.
- Quick and jerky movements (tics).
Treatment depends on how much you need the medicine that causes the symptoms. If symptoms are causing big problems for you, your doctor may have you lower the dose or stop the medicine. Or your doctor may switch you to a different medicine.
Other medicines sometimes can help relieve the TD symptoms. But you may still have symptoms, even if you stop taking the antipsychotic medicine.
