Prednisone is a commonly prescribed medication, and for breastfeeding mothers, concerns about its safety for the infant are natural. Understanding how this medication works and its potential effects on breastfed infants can help mothers and healthcare providers make informed decisions. This information aims to provide clarity on prednisone use during lactation, helping to balance maternal health needs with infant well-being.
Understanding Prednisone
Prednisone is a corticosteroid medication that reduces inflammation and suppresses the immune system. Healthcare providers prescribe it to manage conditions like allergic reactions, asthma, autoimmune disorders (e.g., lupus, rheumatoid arthritis), and inflammatory bowel disease.
It functions by mimicking cortisol, a hormone naturally produced by the adrenal glands that helps the body respond to stress and regulate metabolism. Prednisone is a “prodrug,” meaning the liver converts it into its active form, prednisolone, after it is taken.
How Prednisone Enters Breast Milk
Prednisone, once converted to prednisolone, can transfer from the mother’s bloodstream into breast milk. The amount of medication that enters breast milk is very low.
Several factors influence the quantity of prednisone in breast milk, including maternal dosage, frequency of intake, and timing relative to breastfeeding. Peak levels in breast milk occur about one to two hours after a maternal dose. Even at higher maternal doses, the amount transferred to the infant remains a small fraction of the maternal dose, often less than 1%.
Potential Effects on Breastfed Infants
Prednisone is compatible with breastfeeding, particularly at lower dosages. This compatibility stems from the minimal amount transferred into breast milk and its rapid clearance from an infant’s system. No adverse effects have been consistently reported in breastfed infants whose mothers were taking prednisone.
Theoretical concerns exist with very high maternal doses or prolonged use. These rare effects include growth suppression or temporary adrenal suppression in the infant. Monitoring the infant for unusual changes, such as poor weight gain or excessive sleepiness, is important, especially with higher maternal doses. The benefits of continuing breastfeeding outweigh these minimal risks when prednisone is managed appropriately.
Minimizing Infant Exposure While Breastfeeding
For mothers taking prednisone, strategies can minimize infant exposure through breast milk. A common recommendation is to take the medication immediately after a feeding. Alternatively, taking the dose before the infant’s longest sleep period maximizes the time between medication intake and the next feeding. This timing allows the medication’s concentration in breast milk to decrease before the next feeding.
Consulting with a healthcare provider is important to determine the lowest effective dose for the mother’s condition. Using the lowest necessary dose further reduces the amount of medication that could transfer to the infant. Communicating with the infant’s pediatrician or healthcare provider about maternal medication use enables monitoring for any potential, though rare, side effects. The benefits of breastfeeding outweigh the minimal risks associated with prednisone use when these measures are followed.
