Risk Factors and Precautions
Certain individuals may be at an increased risk of experiencing side effects or complications when taking meclizine. Factors that may increase your risk include:
- Age: Older adults may be more sensitive to the side effects of meclizine, particularly drowsiness, dizziness, and confusion. Therefore, healthcare providers may recommend a lower dosage or close monitoring for this population.
- Medical history: People with a history of asthma, glaucoma, heart problems, high blood pressure, kidney or liver disease, seizures, or an enlarged prostate may be at higher risk for complications when using meclizine. Inform your healthcare provider of your medical history before taking this medication.

Additionally, meclizine can pass into breast milk, so nursing mothers should consult their doctors before using this medication.
Meclizine may interact with other medications, which could increase the risk of side effects or reduce the drug’s effectiveness. Some potential interactions include:
- Sedatives and tranquilizers: Combining meclizine with medications that cause drowsiness, such as benzodiazepines, sleep aids, or antihistamines, can increase the risk of excessive drowsiness or impaired cognitive function.
- Antidepressants: Meclizine may interact with certain antidepressants, such as tricyclic antidepressants or monoamine oxidase inhibitors (MAOIs), leading to an increased risk of side effects.
- Alcohol: Consuming alcohol while taking meclizine can increase the risk of drowsiness and impair your ability to concentrate or perform tasks that require mental alertness. It is best to avoid or limit alcohol consumption while using this medication.
Tips for Managing Side Effects
If you experience side effects while taking meclizine, there are several steps you can take to manage them:
- Drowsiness and dizziness: Avoid engaging in activities that require alertness, such as driving or operating heavy machinery, until you know how the medication affects you. Also, be cautious when getting up from a sitting or lying position to reduce the risk of falls.
- Dry mouth: Stay well-hydrated by drinking water regularly and consider using sugarless gum or candy to stimulate saliva production. You can also use an over-the-counter saliva substitute if necessary.
- Headache: Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can help manage headaches. Be sure to follow the instructions on the label and consult your healthcare provider if your headaches persist or worsen.
