Dystonic Reaction

You have had a dystonic drug reaction. Symptoms usually include painful uncontrolled muscle spasms of the neck, face, or back. This type of reaction is seen most commonly in patients who are given a medicine to control nausea or vomiting. Dystonic reactions also occur during the first few days of treatment with major tranquilizers.

Dystonic reactions do not cause any permanent damage. They are frightening but nothing to worry about. They can usually be controlled with antidote medicines such as Benadryl or Cogentin. You should stop taking the anti-vomiting or tranquilizer medicine as recommended. Continue on the antidote drug for 2 days to prevent further dystonic reactions. Call your caregiver to discuss these changes in your medical treatment.
