Meclizine, a medication commonly used to treat motion sickness and vertigo, has become a topic of concern for pregnant women. As with any medication, it is crucial to understand the risks and benefits associated with its use during pregnancy. In this article, we will explore the uses and effects of meclizine, discuss medical opinions on its safety, and provide alternatives for pregnant women.

Understanding Meclizine: Uses and Effects

What is Meclizine?

Meclizine is an antihistamine medication that belongs to a class of drugs known as anticholinergic agents. It works by blocking certain signals within the brain, which can help alleviate symptoms such as nausea, vomiting, and dizziness.

Meclizine is a widely used medication that has been on the market for several decades. It was first approved by the Food and Drug Administration (FDA) in the 1950s and has since become a staple in the treatment of motion sickness and vertigo. Its effectiveness and safety profile have made it a popular choice among healthcare professionals and patients alike.

When taken as directed, Meclizine can provide relief from symptoms that can significantly impact a person's quality of life. By targeting the underlying causes of nausea, vomiting, and dizziness, it allows individuals to regain their balance and enjoy everyday activities without discomfort or disruption.

Common Uses of Meclizine

Meclizine is primarily used to treat motion sickness, a condition characterized by feelings of nausea and dizziness when traveling in a car, boat, or plane. It is also prescribed to individuals suffering from vertigo, a type of dizziness caused by inner ear problems.

Motion sickness is a common occurrence for many people, especially when embarking on long journeys or engaging in activities that involve rapid or repetitive movements. Whether it's a road trip, a cruise, or a thrilling amusement park ride, the symptoms of motion sickness can quickly turn an enjoyable experience into an uncomfortable one.

Vertigo, on the other hand, is a more persistent and often chronic condition. It can be caused by various factors, including inner ear infections, Meniere's disease, or even certain medications. The sensation of spinning or a loss of balance can be debilitating and significantly impact a person's ability to perform daily tasks.

By targeting the underlying causes of these conditions, Meclizine provides relief and allows individuals to regain their equilibrium. It helps to restore a sense of normalcy and enables people to engage in activities they may have previously avoided due to the fear of experiencing symptoms.

How Does Meclizine Work?

Meclizine works by blocking histamine receptors in the brain, specifically those associated with the inner ear. By doing so, it reduces the stimulation that leads to dizziness and nausea.

When we experience motion sickness or vertigo, our inner ear sends signals to the brain that conflict with the visual information we receive. This mismatch between what we see and what our inner ear senses can trigger a cascade of symptoms, including nausea, vomiting, and dizziness.

Meclizine acts as a mediator in this process by blocking the histamine receptors in the brain that are responsible for transmitting these conflicting signals. By reducing the stimulation in the inner ear, it helps to restore balance and alleviate the associated symptoms.

It's important to note that Meclizine does not cure the underlying causes of motion sickness or vertigo. Instead, it provides temporary relief from the symptoms, allowing individuals to function more comfortably and go about their daily lives.

Meclizine is typically taken orally in the form of tablets or chewable tablets. The dosage and duration of treatment may vary depending on the individual's condition and response to the medication. It is always recommended to follow the prescribed instructions and consult with a healthcare professional for personalized advice.

Meclizine and Pregnancy: A Detailed Look

Meclizine's Role in Treating Pregnancy Symptoms

Many pregnant women experience symptoms such as nausea and dizziness, especially during the first trimester. These symptoms can greatly affect a woman's quality of life and make it difficult to carry out daily activities. In an effort to find relief, healthcare providers may prescribe medications such as meclizine.

Meclizine, commonly known by its brand name Antivert, is an antihistamine that is sometimes prescribed to alleviate pregnancy-related symptoms. It has been found to be effective for motion sickness and vertigo, which are common causes of nausea and dizziness. By targeting the inner ear, meclizine helps to reduce the sensations that trigger these symptoms, providing much-needed relief for pregnant women.

However, the use of meclizine during pregnancy should be carefully considered. While it may offer relief from uncomfortable symptoms, it is important to weigh the potential risks against the benefits.

Potential Risks and Side Effects for Pregnant Women

When it comes to the safety of using meclizine during pregnancy, research is limited. The U.S. Food and Drug Administration (FDA) categorizes meclizine as a pregnancy category B drug, which means it has not been proven to be harmful to unborn babies in animal studies. This classification provides some reassurance, but it is important to note that animal studies may not always accurately reflect the effects on human fetuses.

While meclizine has not been definitively linked to birth defects or adverse outcomes in humans, healthcare providers and pregnant women should exercise caution. It is always best to err on the side of caution during pregnancy, as the safety of the developing fetus is of utmost importance.

It is worth noting that some studies have suggested a potential association between meclizine use during pregnancy and an increased risk of certain birth defects. However, these studies have been small in scale and further research is needed to establish a clear link, if any, between meclizine and birth defects.

As with any medication, the potential risks must be weighed against the potential benefits. If a pregnant woman is experiencing severe symptoms that significantly impact her daily life, her healthcare provider may determine that the benefits of using meclizine outweigh the potential risks. In such cases, close monitoring and regular check-ups are essential to ensure the well-being of both the mother and the developing baby.

It is important for pregnant women to have open and honest discussions with their healthcare providers about the use of meclizine or any other medication during pregnancy. By considering individual circumstances and weighing the risks and benefits, healthcare providers can make informed decisions to provide the best possible care for pregnant women.

Medical Opinions on Meclizine During Pregnancy

FDA Classification of Meclizine for Pregnant Women

The FDA assigns a classification to each medication based on its potential risks during pregnancy. Meclizine falls into category B, which suggests that there have not been sufficient studies conducted in pregnant women to determine its safety conclusively. However, many doctors still prescribe meclizine to pregnant women when the benefits outweigh the potential risks. It is important to consult with a healthcare provider for an informed decision.

Doctors' Views on Meclizine Use in Pregnancy

While some healthcare providers consider meclizine relatively safe for use during pregnancy, others may recommend alternatives due to the lack of extensive research. It is essential to discuss your specific situation with your doctor to fully understand the potential risks and benefits.

Alternatives to Meclizine for Pregnant Women

Natural Remedies for Nausea and Dizziness

Many pregnant women prefer to explore natural remedies before turning to medications. Ginger, for example, has been used for centuries to alleviate nausea and is generally considered safe during pregnancy. Acupressure wristbands and deep breathing exercises are also popular non-medicated options that may provide relief.

Other Safe Medications for Pregnant Women

If meclizine is not recommended or preferred, there are alternative medications that may be suitable for pregnant women experiencing symptoms of motion sickness or vertigo. Promethazine, for example, is another antihistamine that is sometimes prescribed to pregnant women. Again, it is crucial to consult with a healthcare provider before initiating any medication.

Making the Decision: Should You Take Meclizine While Pregnant?

Factors to Consider Before Taking Meclizine

Before deciding to take meclizine during pregnancy, it is important to consider several factors:

  • Your individual medical history

  • The severity of your symptoms

  • Alternative treatment options

Your healthcare provider can provide guidance based on your specific situation.

Discussing Meclizine Use with Your Healthcare Provider

Open communication with your healthcare provider is crucial when making decisions about taking medications during pregnancy.

Together, you can make an informed decision that prioritizes both your wellbeing and the health of your baby.


When it comes to taking meclizine during pregnancy, the available data is limited. While some healthcare providers consider it relatively safe for use during pregnancy, it is essential to discuss the potential risks and benefits with your doctor. Additionally, exploring natural remedies and alternative medications can provide additional options for managing symptoms of motion sickness and vertigo during pregnancy. Remember, the wellbeing of both you and your baby should be the primary concern throughout your pregnancy journey.
