Drug Levels and Effects
Summary of Use during Lactation
Although tamsulosin is not FDA approved for use in women, it is used off-label in women with kidney stones. No information is available on the use of tamsulosin during breastfeeding. Because it is 94 to 99% bound to plasma proteins, amounts in milk are likely to be small. If tamsulosin is required by the mother, it is not a reason to discontinue breastfeeding. However, the breastfed infant should be carefully monitored.
