![]() The milk/ plasma ratio reflects the concentration of a drug in the mother's milk divided by the concentration in her blood. ![]() For antidepressants, paroxetine (half-life 21 hours), is a better choice than fluoxetine (half-life of 2≣ days). So for example, among anti-inflammatories, ibuprofen (half-life 1.8≢.5 hours) is a better choice than naproxen (half-life 12≡5 hours). A woman on a medication with a half-life of 2 hours can take her medication immediately after breastfeeding, and most of the drug will have cleared her system by the next feeding. For lactating women, drugs with a short half-life are preferred. TABLE 1 Which drugs are OK for mothers to take while breastfeeding? Factors to be considered when assessing the safety of drugs taken by lactating women include passive diffusion, molecular weight (MW), plasma protein binding, half-life, milk/plasma ratio, oral bioavailability, volume of distribution, ionization characteristics, and lipid solubility (Table 1). ![]() To gain access into breast milk, a drug in the maternal circulation must first cross the capillary endothelium, enter into the mammary alveolar cell and then be secreted into the lumen of the alveolus. The principles of pharmacokinetics govern drug transfer across membranes into breast milk as well as drug metabolism in the mother and nursing infant. Our goal here is to help busy clinicians understand this often confusing area of health care. Weaning, even temporarily, is traumatic for both mother and baby. Women are often advised against breastfeeding even when the medication of concern is actually approved for use in infants. Mothers should balance short-term concerns over medication with the longer-term health risks of formula feeding. A baby may not accept "temporary weaning." In fact, he or she may stop feeding altogether. In our experience, clinicians and many of the resources they turn toare too cautious when providing advice on breastfeeding and medications. 2,3 One report suggests that half of all mothers are more reluctant to take medication while nursing than during their pregnancy. Unfortunately, all too often that concern translates into noncompliance, unnecessary weaning, or complete avoidance of breastfeeding. 1 It should come as no surprise to discover that many of these women worry about whether these drugs will harm their nursing infant. Two experts in this area provide an informed, balanced perspective.Ībout nine out of every 10 breastfeeding women are prescribed some type of medication during their first week postpartum.

Another useful tip is to shorten the length of each breastfeeding session.Instead of stopping breastfeeding suddenly, mothers should gradually stop breastfeeding by reducing the number of breastfeeding sessions over a few weeks. ![]() This may be a problem if the baby doesn’t take to formula or solid food easily. The nutritional advantage of breast milk is lost, and dependency on external nutrition increases.The risk of infection increases as breast milk contains antibodies that fight off infections, which the baby is no longer consuming. ![]()
