Safety in Lactation: Contrast media

Sarah Fenner, Specialist MI Pharmacist, Midlands and East Medicines Advice Service (Midlands site) & UK Drugs in Lactation Advisory ServicePublished

Only very small amounts of iodinated or gadolinium-based contrast medium given to a lactating mother reach the milk, and only a minute proportion entering the infant’s gut is absorbed. The very small potential risk associated with absorption of contrast medium is considered insufficient to warrant suspending breastfeeding for any period following either iodinated or gadolinium contrast agents.
