WHAT YOU NEED TO KNOW: What are extrapyramidal symptoms? Extrapyramidal symptoms (EPS) are side effects of antipsychotic medicines. EPS can cause movement and muscle control problems throughout your body. What symptoms may I have? Symptoms may be noticed after you take one dose of medicine or after long-term use. You may not be aware of these symptoms, but others close to you may notice any of the following: - Restlessness and nervous energy shown by pacing, marching, shuffling, or foot-tapping
- Severe, uncontrolled muscle contractions of your head, neck, trunk, and limbs that cause stiff tongue, twisted neck, or back arching
- Tremors, stiff posture, or no arm movement when you walk
- Uncontrolled movements of your tongue, jaw, lips, or face, such as pursing, chewing, or frequent eye blinking
- Uncontrolled movements of your fingers or toes, head nodding, or pelvic thrusting
- Fast, irregular breathing with grunts, gasping, or sighing
- Weak voice, drooling, or little or no facial expression
What should I do if I or someone close to me notices that I have symptoms? - Do not stop taking your medicines unless your healthcare provider says it is okay.
- Contact your healthcare provider.
- Take a list of your medicines with you to your appointment.
