Tardive Dyskinesia Q&A
What is tardive dyskinesia?
Tardive dyskinesia, a neurological disorder, is caused by taking specific medications namely dopamine blocking medications such as antipsychotic medications or dopamine blocking anti nausea medications. These medications can cause involuntary movements that can be embarrassing and lead to social isolation. These movements affect your tongue, face, lips, torso, arms, legs, and hands and feet.
- Rapid blinking and eye-twitching
- Frowning, sticking out the tongue, pursing of the lips
- Rapid arm, leg, and torso movement
- Hand-wringing and/or foot-tapping
Sometimes difficulty swallowing, facial distortion, and difficulty breathing can result.
What are the causes of tardive dyskinesia?
Tardive dyskinesia usually happens when you take specific neuroleptic drugs to treat psychiatric disorders. The condition can develop after months or years on these medications.
Older antipsychotic drugs are the ones that most cause tardive dyskinesia. These drugs include:
- Chlorpromazine (Thorazine® and Largactil®)
- Fluphenazine (Prolixin®)
- Haloperidol (Haldol®)
- Perphenazine (Trilafon®)
- Prochlorperazine (Compazine®)
- Thioridazine (Mellaril®)
- Trifluoperazine (Eskazine® and several other brand names)
Metoclopramide, a medicine taken for stomach problems, can also cause tardive dyskinesia. Not everyone who takes these drugs experiences movement disorder as a side effect. Newer antipsychotics are less likely to cause the problem, but they aren’t without risk.
Is tardive dyskinesia rare?
About 500,000 people in the United States are affected by tardive dyskinesia. That’s about 10% of all people who take the previously mentioned medications. Those most at risk include people who are:
- Female gender
- Older than 55
- On any of the medications mentioned above for an extended period
