Levonorgestrel tablets is a kind of emergency contraceptive containing progestin, once in a while after taking breastfeeding, the baby usually does not have an effect, during this period you need to let the child drink a lot of water, and to avoid recurrence of similar situations. Because the drug will enter the baby’s body through the breast milk, if you breastfeed after a long period of taking contraceptive pills, it will affect the normal growth and development of the baby. In addition, because the contraceptive pill contains estrogen or progesterone, it will affect the level of estrogen and progesterone in the baby’s body, and there is a risk of causing the baby to develop prematurely, resulting in the phenomenon of precocious puberty. If a breastfeeding woman breastfeeds after taking levonorgestrel tablets once in a while, it usually has little effect on her baby, so she can let her baby drink plenty of water and stop breastfeeding for a while, and then continue to breastfeed after 72 hours of taking the pill. In the future, you can avoid breastfeeding after taking the medicine again. It is not recommended to take levonorgestrel tablets or other emergency contraceptives during breastfeeding, but to use condoms for contraception.
