Benzocaine

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Local anesthetic indicated for the relief of cutaneous, vaginal, rectal, otic, dental and oral mucosa pain and itching.
Topical application.

Since the last update we have not found published data on its excretion in breastmilk.

Topical anesthetics (dermatological, otological and stomatological preparations) when applied well have virtually no systemic absorption through intact or mucosal skin, so that levels in plasma and breastmilk are zero or insignificant and do not pose any danger to the infant (Hale 2019 p, PDR 2018, AEMPS 2018, Briggs 2017, AEMPS 2008, Nice 2000).

Benzocaine can produce methemoglobinemia and systemic toxicity if absorbed (PCR 2018, AEMPS 2018, Hoffman 2015, Lepe 2015, Bittmann 2011, Chung 2010, Bouziri 2010, Bong 2009).

Do not apply to the breast or, if necessary, apply after a feed and clean thoroughly with water before the next one.
Never apply to the nipple.

Alternatives

  • Lidocaine ( Safe. Compatible. Minimal risk for breastfeeding and infant.)

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.

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.
