Meclizine hydrochloride (HCL) is the generic name for a prescription medication. Doctors commonly prescribe meclizine HCL for the treatment of nausea and vomiting due to motion sickness or vertigo.
Doctors typically prescribe between one and four meclizine HCL 25 mg tablets for use every 24 hours for the treatment of vertigo, reports RxList. For motion sickness, it is one or two meclizine HCL 25 mg tablets every 24 hours while traveling by car, boat, airplane or train.
Meclizine HCL 25 mg tablets are dispensed in bottles of either 100 or 1000. If you are receiving the drug for occasional motion sickness, your doctor is more likely to authorize you to receive fewer pills.
Types of Side Effects
The most common side effects of meclizine HCL 25 mg tablets are drowsiness and dry mouth, reports RxList. Blurred vision is another rare side effect of meclizine HCL.
Because it has the potential to cause drowsiness, do not drive or operate a motor vehicle while taking meclizine HCL 25 mg tablets. It is also important to avoid alcohol as drinking increases the sedative properties of the drug, cautions RxList.
Meclizine 25 mg tablets are not recommended for use by pregnant women or children under 12 years of age. If you have a history of asthma, emphysema, chronic obstructive pulmonary disease, an enlarged prostate, glaucoma, intestinal or urinary tract blockages or heart failure, it may not be safe for you to take meclizine HCL, warns the Mayo Clinic.
