Cyclizine is an antihistamine that prevents and treats motion sickness.
What are cyclizine’s uses?
Cyclizine is used in the prevention and treatment of nausea, vomiting or dizziness caused by motion sickness.
Its other benefit is the prevention and treatment of vertigo (loss of balance), nausea and vomiting caused by so-called labyrinthine disorders (diseases affecting the inner ear) like labyrinthitis and Meniere’s disease.
What dosage should you take?
A typical oral dose for nausea/vomiting is 50mg three times daily. As a suppository, the dose is 100mg three times daily.
For the prevention of motion sickness specifically, take 50mg orally 20 to 30 minutes before departure, and repeat four to six hourly if necessary.
However, first check the correct dosages with your Clicks pharmacist, including paediatric dosages.
What special precautions should you take?
- Cyclizine should not be used by children younger than six years old.
