At latest update, relevant published data on excretion into breast milk were not found. Topical anesthetics (intended for dermatological or oral use) when properly used, show limited systemic absorption which is practically nil, with nil or non-significant systemic levels in the plasma and breast milk. Benzocaine may induce appearance of methemoglobinemia and systemic toxicity if absorbed. Avoid use on the breast, otherwise, in case of use on the nipple, let it be done after a feed and wipe it out by thoroughly washing with water before the next feed. Do not apply creams, gels and other products that would contain paraffin (mineral oil) to avoid absorption by the infant since it is a hydrocarbon-derived substance.

Dimethicone is a fluid type of silicone with a methyl as organic group radical. Silicones are polymers of silicon tied to oxygen atoms with high molecular weight (see information on silicone and dimethicone). Dimethicone is water repellent and it is used in creams, dressings for skin protection and pediculicides. An activated form of Dimethicone is Simethicone that is used for treatment of flatulence (see info on Simethicone) At latest update, relevant published data on excretion into breast milk were not found. Because it is not absorbed through the skin or orally along with a high molecular weight, excretion into breast milk in significant amount or absorption by the infant gut is highly unlikely.

Substance which can be extracted under distillation from the Camphor tree bark. Nowadays it is synthesized from the Turpentine. Used with creams and lotions as local anti-inflammatory agent. There is no proof of effectiveness as decongestant or expectorant when used in inhaled preparations, but as a toxic agent. Camphor is a highly lipophilic substance which is well absorbed by whatever via of administration (skin, inhalation, mouth) that crosses easily the cell membrane. Pharmacokinetic data support the likelihood of excretion into breast milk in a significant amount. Camphor has been shown to be toxic at low dose on infants in whom it may cause headache, vomiting, seizures and coma. It should never be administered by mouth. It is not appropriate its use during breastfeeding, and, in whatever case, it should not be applied on the mother's breast, since severe intoxications be occurred in infants after use of small ingested amounts. Be aware of not using it in the nostrils.
Herb which is widely used by many cultures. It has been used even for pain relief during pregnancy and colicky pain in fussy babies (without proved data on this). Since it is non toxic at appropriate dose and a tiny excretion into breast milk of active metabolite Menthol, a moderate consumption is believed compatible while breastfeeding. Dessicated leaves and essential oil of the plant that contains Menthol are used. Properties that have been demonstrated and approved indications are: as spasmolytic for Dyspepsia, Irritable Colon and flatulence. It has been used for the treatment of cracked nipple with best results than placebo or Lanolin. Although with no proven effectiveness, it is traditionally used for cough relief, common cold, pain or itching by local application or inhalation. Overdosing of essential oil may be harmful. Do not expose infants to inhalation of products that contain Menthol (irritation of the air way) In case of use on the nipple, do it after feeding the baby and cleanse thoroughly the surface before the next one.

Topical benzocaine has not been studied during breastfeeding, but is unlikely to affect her breastfed infant if it is applied away from the breast. Benzocaine should not be applied to the breast or nipple, because the infant may ingest the drug during nursing and it has been associated with severe methemoglobinemia.
Peppermint (Mentha x piperita) contains menthol, menthone, menthyl acetate as major ingredients. Minor ingredients include 1,8-cineole, pulegone, bitter substances, caffeic acid, flavonoids, and tannins. Peppermint is a purported galactogogue; however, no scientifically valid clinical trials support this use. Galactogogues should never replace evaluation and counseling on modifiable factors that affect milk production. Topical peppermint gel and solutions have been studied for the prevention of pain and cracked nipples and areolas in nursing women. The peppermint preparations were more effective than placebo and expressed breastmilk, and about as effective as lanolin, although a meta-analysis concluded that application of nothing or breastmilk may be superior to lanolin, but good studies are lacking. Menthol is excreted into breastmilk in small quantities; the excretion of other components have not been studied. Peppermint is "generally recognized as safe" (GRAS) as a food by the U.S. Food and Drug Administration. Large doses can cause heartburn, nausea and vomiting. Allergic reactions, including headache, have been reported to menthol. If peppermint is used on the nipples, it should be used after nursing and wiped off before the next nursing. Dietary supplements do not require extensive pre-marketing approval from the U.S. Food and Drug Administration. Manufacturers are responsible to ensure the safety, but do not need to the safety and effectiveness of dietary supplements before they are marketed. Dietary supplements may contain multiple ingredients, and differences are often found between labeled and actual ingredients or their amounts. A manufacturer may contract with an independent organization to verify the quality of a product or its ingredients, but that does certify the safety or effectiveness of a product. Because of the above issues, clinical testing results on one product may not be applicable to other products. More detailed information #about dietary supplements# is available elsewhere on the LactMed Web site.
