Cinnarizine

Cinnarizine is a medication primarily used to treat nausea and vomiting, and to prevent and treat vertigo and other symptoms of balance disorders. It is also used to treat migraines and to improve memory and attention in the elderly.

Pharmacology

Cinnarizine is a calcium channel blocker and an antihistamine. It works by preventing the tightening of the blood vessels in the brain, which helps to reduce the frequency and severity of migraines. As an antihistamine, it reduces the effects of natural chemical histamine in the body, which can lead to symptoms such as sneezing, itching, watery eyes, and runny nose.

Side Effects

Common side effects of cinnarizine include drowsiness, nausea, dry mouth, and weight gain. In rare cases, it can cause serious side effects such as jaundice, anemia, and liver disease. If you experience any of these side effects, you should contact your doctor immediately.

Interactions

Cinnarizine may interact with other medications, including antidepressants, antipsychotics, and antihistamines. It is important to tell your doctor about all the medications you are currently taking to avoid potential interactions.

Dosage

The dosage of cinnarizine depends on the condition being treated. It is usually taken with or without food. The usual dose for adults is 25 to 50 mg three times a day. For children, the dose is usually lower.

Precautions

Before taking cinnarizine, tell your doctor if you have any allergies or if you have a history of liver disease, kidney disease, or heart disease. It is also important to tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
