Dihydrochloride of 2-[4-(4-chlorobenzhydryl)piperazin-1-yl]ethoxyacetic acid

Very Low Risk for breastfeeding


Safe. Compatible.
Not risky for breastfeeding or infant.

A second generation antihistamine, derived from piperazine and hydroxyzine metabolite, with minimal sedative effects and very low toxicity even at high doses.

No problems were detected in the short or long term in an infant whose mother took it during the first month after delivery as part of the treatment for pemphigus (Westermann 2012).

Its high binding to plasma proteins makes its transfer to milk very unlikely.

The British Society for Allergy and Clinical Immunology and other experts consider it safe during breastfeeding (Butler 2014, Powell 2007).
