Very Low Risk
Insufficient vaginal lubrication causes urinary discomfort, vaginal itching and pain during sexual intercourse (dyspareunia) (MedlinePlus 2017). The most frequent cause is estrogen deficiency (MedlinePlus 2017) which produces a temporary or permanent atrophy or hypotrophy of the vaginal wall.
It can occur in diseases such as multiple sclerosis (Cordeau 2014), diabetes (Carati 2016), Sjögren's syndrome (Romão 2018), endometriosis, depression, stress, some anticancer and hormonal drugs (eg tamoxifen), pelvic radiotherapy and also appears in circumstances such as breastfeeding (Agarwal 2015, Anzaku 2014, Solana 2008, Barrett 2000) and menopause (MedlinePlus 2017).
Irritating soaps and perfumes should be avoided. The treatments used are non-hormonal (water-based lubricants or vaginal moisturizers), non-hormonal topical applications such as creams, gels or ovules), and whether they are topical estrogens (Zsolnai 1982) or systemic, they are compatible with breastfeeding.
Oral estrogens have very low (<10%) oral absorption (O'Connell 1995).
The vaginal absorption of estrogens can be minimized using low/minimal doses or certain preparations (Santen 2015, Del Pup 2013 and 2012, Tan 2012, Bhamra 2011, Eugster 2010).
Estrogens have a high (98%) binding to plasma proteins (O'Connell 1995), so they are not excreted in breastmilk in significant amounts.
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.
