Summary
Meclizine is used to prevent and treat symptoms of motion sickness such as nausea, vomiting, and dizziness. It can also be used for dizziness caused by certain ear conditions.
Meclizine works as an antihistamine with antiemetic properties. It blocks signals in the brain that trigger nausea, vomiting, and dizziness, particularly those related to motion sickness.
For adults and children over 12 years, the usual dose is 24 caplets once daily. For children under 12 years, it is advised to consult a doctor for the appropriate dosage. Meclizine should be taken 1 hour before travel for motion sickness.
Common side effects of Meclizine include drowsiness, fatigue, and dry mouth. A serious side effect is blurred vision. If these symptoms are severe or persistent, contact your doctor.
Meclizine can increase drowsiness, especially when combined with alcohol or sedatives. It can also cause blurred vision, which may impair your ability to drive or operate machinery. It is important to inform your doctor if you have glaucoma, an enlarged prostate, urinary tract blockage, or asthma before taking Meclizine.
