How Long Does it Take for Cyclizine to Work?

Cyclizine is a medication commonly used to relieve nausea and vomiting. It is particularly effective for nausea caused by conditions such as vertigo, travel sickness, inner ear problems, radiotherapy, or after surgery involving general anaesthesia.

In this guide, we will break down how cyclizine works, how long it takes to relieve nausea, and important information you should know about this medication.

Cyclizine Quickly Relieves Nausea and Vomiting

Cyclizine, an antihistamine, starts to work within 30 minutes, with full relief typically felt in 1-2 hours. Its effects last about 4 to 6 hours, making it effective for motion sickness, vertigo, and post-surgery nausea.

How Cyclizine Works

Cyclizine blocks nausea signals from reaching the brain’s vomiting centre, reducing symptoms of nausea and vomiting, especially from inner ear issues and motion sickness.

Who Should Avoid Cyclizine

Most people over 6 can safely take cyclizine, but it may not be suitable if you have conditions like glaucoma, high blood pressure, or liver problems. Always consult a healthcare provider if you're unsure.

What Is Cyclizine?

Cyclizine is an antihistamine that works by blocking signals in the brain that cause nausea. It contains the active ingredient Cyclizine, which helps to stop the vomiting centre in the brain from reacting to triggers like motion, certain medical conditions, or after a surgical procedure.

Cyclizine can be used by both adults and children aged 6 years and older, and is available as an over-the-counter medication in the UK. It’s commonly used to prevent or treat nausea and vomiting due to a variety of causes, including:

• Travel sickness or motion sickness

• Vertigo or dizziness caused by inner ear problems

• Nausea following radiotherapy treatments

• Post-operative nausea after surgery involving general anaesthesia

How Long Does Cyclizine Take to Work?

Cyclizine is typically fast-acting, and most people begin to feel relief within 30 minutes of taking the medication [1]. You should start to notice a reduction in nausea and vomiting symptoms within 1-2 hours after taking it. The effects of cyclizine usually last for about 4 to 6 hours, providing temporary relief from nausea.

Key Points:

• Cyclizine starts to work within 30 minutes of taking it.

• You should feel better within 1-2 hours after taking cyclizine.

How Does Cyclizine Work?

Cyclizine works by blocking receptors in the brain that trigger nausea and vomiting. It prevents signals from the vestibular system (the part of the inner ear involved in balance) from reaching the brain’s vomiting centre. This helps to stop the body’s reaction to nausea, making you feel calmer and more comfortable.

Unlike some medications that target the stomach or digestive system, cyclizine works centrally in the brain, offering relief from nausea caused by a variety of factors such as motion sickness, inner ear issues, or the aftereffects of anaesthesia.

Cyclizine is safe for most people aged 6 years and older. However, like any medication, it’s important to be aware of situations where cyclizine may not be suitable.
