How long can you breastfeed your baby again after taking antipyretic medication needs to be analyzed on a case-by-case basis. If the mother has taken antipyretic medicine, it is recommended to stop taking the medicine for 3 days before breastfeeding; if the baby has taken antipyretic medicine, it is recommended to breastfeed 2-4 hours after taking the medicine. If the mother has taken antipyretic drugs, the drugs can enter the breast milk after being absorbed by the organism, and if fed within a short period of time, it may have an adverse effect on the baby’s growth and development, so it is recommended to breastfeed 3 days after stopping the drugs. In addition, you should drink more water, rest more, strengthen nutrition and actively treat the original disease. If your baby takes antipyretic medicine after having a fever, it is generally recommended to breastfeed after 2-4 hours to avoid affecting the absorption of the medicine. If the baby appears hungry and keeps crying, a small amount of nursing can be done, never too much to avoid vomiting and other situations. In conclusion, both mother and baby are advised to drink more water, rest more, eat a light and easy to digest diet, pay attention to keeping warm and avoid getting cold during the fever. If the fever persists, you should go to the hospital promptly.
