Antivert is an anti-emetic drug which works to block the signals to the brain that cause nausea, vomiting, and dizziness.
This drug is useful mainly in motion sickness and to a lesser extent in morning sickness, postoperative and some other forms of vomiting. However, it is less sedative and longer-acting anti-emetic that protects against sea sickness for nearly 24 hours.
Meclizine blocks the vasopressor response to histamine and has a slight blocking action against acetylcholine. It decreases the excitability of the middle ear labyrinth and blocks conduction in the middle ear vestibular-cerebellar pathways. Thus, it is also used for vertigo and vestibular disorder.
This medicine is available only with your doctor's prescription. This product is available in the following dosage forms:
2 What to Know Before Using
Before using Antivert, you must know all about the risks and complications associated with it. The suitable drug therapy is chosen by a doctor with the active participation of the patient.
There are some important factors such as drug interactions, the presence of any metabolic impairment, history of hypersensitivity reaction, pregnancy, lactation etc. that may alter the desired therapeutic effects of a medicine. Sometimes the presence of other health disorders affects the beneficial effects of this medicine and even may cause serious toxic effects.

Animal reproduction studies have shown an adverse effect, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus in any trimester.
Thus, this drug should be used during pregnancy only if clearly needed and caution is recommended when it is used in lactating women.
