Cyclizine is a first generation antihistamine and antiemetic drug derived from piperazine used for the prevention and treatment of nausea, vomiting and dizziness associated with motion sickness and vertigo and in Ménière's vertigo. Moderate sedative effect. Oral administration up to three times a day.

At the time of the last update, we found no published data on its excretion in breast milk.

The scarce pharmacokinetic data published do not allow predicting its possible excretion in breast milk, although some authors consider it moderate. (Solhaug 2004)

Pending further published data on this drug in relation to lactation, safer known alternatives may be preferable, especially during the neonatal period and in case of prematurity. (Nice 2000)


  • Dimenhydrinate (Safe substance and/or breastfeeding is the best option.)
  • Diphenhydramine (Safe substance and/or breastfeeding is the best option.)

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.

José María Paricio, founder of e-lactancia.
