Cinnarizine

Cinnarizine is an antihistamine that helps stop nausea and/or vomiting. It has noticeable sedative properties in contrast to other antihistamines and can make you feel drowsy or sleepy. It is often used to treat travel sickness and dizziness caused by inner ear problems, such as tinnitus, vertigo, and Meniere's disease. It works by preventing H1 histamine receptors from receiving nerve signals sent by the part of your ear involved in balance, which then allows it to reduce or block the effects of histamine in your brain that cause sensations like vertigo, nausea, and the vomit reflex.

Cinnarizine is sold in 15-mg tablets and the dosage will depend on the reasons for taking it. It is recommended that you take your cinnarizine tablets after a meal so that it will be less likely to upset your stomach. The tablets can be sucked, chewed, or swallowed whole with a glass of water.
