Dystonic drug reaction causes symptoms such as fast and irregular heart rate, fever, sweating, confusion, and uncontrollable muscle movements of mouth, tongue, cheeks, arms, eyes, or legs.
It is a very alarming side affect to taking a certain medicine. It's a very rare side affect but can happen. The muscle spasms can be very painful and annoying. But it's treatable with medicines like benadryl.
I was taking Geodon for only 3 days and I started to have all the symptoms of dystonic drug reaction. It was so horrible I couldn't control my tongue or close my mouth!
