Indications

Vertigo Nausea and Vomiting

Clizin tablets are used to manage the nausea, vomiting and dizziness associated with motion sickness, and vertigo caused by diseases affecting the vestibular system.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Meclizine works as an antiemetic with anticholinergic and antihistaminic effects, and it lowers the sensitivity of the inner ear's labyrinthine apparatus. This action likely involves nerve pathways connecting the chemoreceptor trigger zone (CTZ) to the vomiting center (VC), along with peripheral nerve pathways, the VC itself, or other centers within the CNS. Its effects typically begin within 30 to 60 minutes, depending on the dose, and last between 12 and 24 hours.

Pregnancy & Breastfeeding

Pregnancy Category B (FDA). Not established as safe for breastfeeding mothers.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
