Side Effects of Cyclizine

Cyclizine is a medication commonly used to help with motion sickness and nausea, and works by affecting certain signals in the brain that are responsible for causing these symptoms – helping to reduce feelings of queasiness and discomfort. 

But like with taking any medicine, some people taking cyclizine may experience unwanted side effects and it’s important to know what those side effects could be, how severe they could be and when you should seek medical attention.

Common Side Effects - More than 1 in 100 people

These common side effects of cyclizine, which happen in more than 1 in 100 people, are usually mild and tend to go away by themselves:

  • Feeling drowsy
  • Having a dry mouth
  • Headaches
  • Constipation (trouble having a poo)
  • Blurred vision

If these side effects continue to bother you, speak with your GP or pharmacist for further guidance. 

Serious Side Effects - Call 111 or visit 111.nhs.uk now

While serious side effects from cyclizine are rare, occurring in less than 1 in 10,000 people, it’s important to recognise and respond to them promptly. If you experience any of the following symptoms, don’t hesitate to contact your doctor or call 111 for immediate medical assistance:

  • Muscle stiffness or shaking, or unusual movements of the face or tongue
  • Severe bleeding or inability to stop bleeding, such as cuts or nosebleeds lasting more than 10 minutes
  • Yellowing of the whites of the eyes or skin, which could indicate liver issues


For a full list of Cyclizine’s side effects, please read through the leaflet inside your medicine packaging which will give you a fully-detailed list of the potential side effects.
