Let's take a minute to talk about your medication. 

This is meclizine, and you should take it as directed by your doctor. 

Meclizine is an antihistamine. It helps control nausea, vomiting, and dizziness from motion sickness and other disorders, like vertigo. 

At first, this medicine can have some side effects. Most patients will feel drowsy or dizzy, so don't do activities that require you to be alert, like driving, until you know how it affects you. It can also cause a dry mouth or headache. These effects are normal if they are mild. If your doctor tells you to take this medicine consistently, your body should adjust to these effects after a few days. But, if these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist.

As with any medicine, serious side effects can occur. You should read the Patient information Sheet to know what symptoms to watch for and when to report them. Contact your doctor right away if you notice any unusual changes to your body, like blurry vision or problems urinating.

To reduce side effects, you should ask your doctor or pharmacist before taking any new medicines, even if they don't require a prescription. It's important to avoid other medicines that also cause drowsiness, and to avoid drinking alcohol. 

Women should talk to their doctor before becoming pregnant or breastfeeding.

For best results, take meclizine as directed, and talk to your doctor if you don't get the results you were expecting.
