Radiologic procedures


Safe substance and/or breastfeeding is the best option.

X-rays, CT scans and other X radiations, such as mammography that are done to a mother do not affect the human milk or breastfeeding (HSE 2015). X rays used neither remain in the body nor are excreted in the milk.
The X radiation does not alter Prolactin levels.

The various contrasts used for these scans (whether Iodine or not) are compatible with breastfeeding because they are biologically inert, undergo a very rapid body clearance without iodine released particles and not excreted in the milk. Furthermore, it cannot be orally absorbed by the infant.
You can consult one by one of them, by searching on a particular name.

After a radiological examination, even with iodinated contrast, it is not necessary to transiently withheld nursing (Mitchell 2019, ACR 2018 p99, Cova 2014, Quintana 2014, Sachs 2013, Tremblay 2012, Wang 2012, Chen 2008, Newman 2007, Webb 2005, Nielsen 1987).
You may search for Mammography under its proprietary name.

Avoid unnecessary testing (as they use radiation emissions).

A number of dye materials (iodine based or not) used for diagnosis imaging procedures (x-Ray, CAT scan, MRI) are compatible with breastfeeding since they are inert, metabolize rapidly without leaving free iodine and are not or very little absorbed by the gastrointestinal tract.

Look after diverse dyeing material being used.

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.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

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.
