Meclizine

Meclizine (proposed INN is meclozine) is an antihistamine, considered to be an antiemetic. It is most commonly used to inhibit nausea and vomiting. An alternative to dimenhydrinates like Dramamine, Meclizine is considered to perform the same functions at an equitable level of effectiveness, but with reduced side effects.

Uses

Motion Sickness

Meclizine is effective in inhibiting the symptoms of motion sickness, such as nausea, vomiting, and dizziness.

Vertigo

Meclizine may be effective in relieving vertigo experienced as a result of inner ear infections or other conditions.

Risks of Use

Drowsiness

Drowsiness may result as a side effect of taking Meclizine. While the effects are less than Dramamine, users are advised not to operate heavy machinery while under the influence. The consumption of alcohol while under the influence of Meclizine may result in additional drowsiness.

Pregnancy

Studies have shown that cleft palates of foetuses were formed when pregnant rats were exposed to 25-50 times a normal dosage. Nevertheless, pregnant women are advised not to take Meclizine unless it is absolutely necessary.

Anticholinergics

Due to its possible anticholinergic action, Meclizine should be used carefully with patients who suffer from asthma, glaucoma, or an enlarged prostate gland.
