Meclizine

Meclizine is a medication that is commonly used to treat and prevent motion sickness, vertigo, and dizziness caused by inner ear problems. It belongs to a class of drugs known as antihistamines and works by reducing the activity of certain natural substances in the body that can cause these symptoms. Meclizine is available in both prescription and over-the-counter forms.

Meclizine is usually taken orally in the form of tablets or capsules. It is absorbed well by the body and reaches its maximum effect within 1-2 hours after ingestion. The duration of its action can vary depending on the individual, but it usually lasts for about 24 hours.

This medication is primarily used to relieve symptoms such as nausea, vomiting, and dizziness associated with motion sickness. It can also be effective in treating vertigo, a condition characterized by a spinning sensation, and dizziness caused by inner ear problems. Meclizine is generally well-tolerated, and serious side effects are rare when taken as directed.

Restrictions

Meclizine should not be used in individuals who have a known hypersensitivity to any of its components. It is also contraindicated in patients who have narrow-angle glaucoma, urinary retention, severe liver disease, or respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD).

Caution should be exercised when using Meclizine in individuals who have a history of alcoholism, liver disease, kidney dysfunction, or certain heart conditions. It is important to inform your healthcare provider about all your medical conditions before starting this medication.

This drug should not be used in children under 12 years old unless specifically directed by a healthcare professional. Pregnant women should consult their doctor before taking Meclizine as its safety during pregnancy has not been established.

Meclizine is generally safe for use while breastfeeding, but it is always advisable to consult a healthcare provider before taking any medication while breastfeeding.
