Meclizine Patient Tips

How it works

Meclizine acts on histamine receptors to relieve the symptoms of motion sickness.


  • Used to treat nausea, vomiting and dizziness associated with motion sickness.
  • May also be used to relieve symptoms of vertigo associated with diseases such as labyrinthitis and Meniere's disease.


If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:

  • May cause drowsiness and affect a person's ability to drive or operate machinery. Avoid alcohol.
  • May also cause a dry mouth and rarely, blurred vision.
  • Not recommended for use in children under 12 years of age.

Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

Bottom Line

Meclizine effectively relieves symptoms such as nausea and vomiting associated with motion sickness; however, it may cause drowsiness.


  • Take one hour prior to travel when used to prevent motion sickness from developing. Dosage may be repeated after 24 hours.
  • Do not drive or operate machinery if meclizine makes you drowsy or impairs your judgement.
  • Not recommended for use in children under 12 years of age.

Response and Effectiveness

Onset of effect takes approximately one hour when used for motion sickness. Recommendation is to take an hour before travel to get maximum benefit. Effects persist for 8 to 24 hours
