Side effects

---

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

High doses or long-term use of prochlorperazine can cause a serious movement disorder that may not be reversible. The longer you use prochlorperazine, the more likely you are to develop this disorder, especially if you are a diabetic or an older adult.

Call your doctor at once if you have:

• uncontrolled muscle movements in your arms, legs, or face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement);
• a light-headed feeling, like you might pass out;
• agitation;
• jaundice (yellowing of the skin or eyes);
• slow heart rate, weak pulse, fainting, slow breathing;
• fever, chills, sore throat, mouth sores;
• new or worsening symptoms of lupus--joint pain, and a skin rash on your cheeks or arms that worsens in sunlight; or
• severe nervous system reaction--very stiff (rigid) muscles, high fever, sweating, confusion, fast or uneven heartbeats, tremors, feeling like you might pass out.

Side effects such as dry mouth, constipation, confusion, and tremors may be more likely in older adults.

Common side effects may include:

• dizziness, drowsiness;
• feeling restless or jittery;
• blurred vision;
• constipation;
