It is topically used as a keratolytic, antiseptic, antifungal, dermatological and stomatological agent. At last update no published data on excretion into breast milk were found . Systemic absorption (distribution into the body) depends on the concentration of the product used and the duration of application. Absorption may reach 10 to 25% of the total amount applied on the skin. It is recommended not to use during lactation in large areas of skin or for prolonged periods. Available data on the elimination of Acetylsalicylic acid (Aspirin-ASA) in breast milk indicates it is clinically insignificant.No cases have been reported on Reye's syndrome by ASA through the breast milk which is considered very unlikely to occur with isolated and/or small doses used as antithrombotic treatments and anti-abortion measures, even less after application on the skin or topically in the mouth. Do not apply on the breast to prevent ingestion by the infant. If necessary, apply it after the feed and wipe it off thoroughly with water before the next feed.

Capsaicin is an oleoresin contained in ripe and dry fruits of hot peppers. It is used for seasoning food and as medicine for topical analgesia in the form of creams, gels or patches. A low absorption into plasma (very low levels or undetectable in plasma) and rapid clearance make it highly unlikely the passage of significant amount toward breast milk. Do not apply on the chest or thoroughly clean it off before breastfeeding.

No information is available on the clinical use of salicylic acid on the skin during breastfeeding. Because it is unlikely to be appreciably absorbed or appear in breastmilk, it is considered safe to use during breastfeeding.[1] Avoid application to areas of the body that might come in direct contact with the infant's skin or where the drug might be ingested by the infant via licking.
