Introduction
In general, whether it is safe to breastfeed after taking ibuprofen for fever during lactation depends on several factors, including the time interval after medication, the baby's health condition, and medical guidance. If any discomfort occurs, it is recommended to seek timely evaluation and treatment at a正规 hospital. When using ibuprofen, it is important to follow a doctor's instructions to determine the proper dosage and the appropriate interval between medication and breastfeeding; self-adjustment of the regimen should be avoided.

Generally, whether it is safe to breastfeed while taking ibuprofen during lactation when experiencing a fever depends on several factors, including the time interval after medication, the baby's health condition, and medical guidance. If any discomfort occurs, it is recommended to seek timely evaluation and treatment at a正规 hospital. The specific considerations are as follows:

If ibuprofen is taken at the standard dose as advised by a doctor, breastfeeding is generally considered safe when resumed 4–6 hours after taking the medication—provided the baby is healthy, has no history of allergies, and no underlying medical conditions. By this time, most of the drug will have been metabolized, and only a minimal amount enters breast milk, unlikely to cause noticeable effects on the infant. In such cases, normal breastfeeding can continue.

However, if insufficient time has passed since taking the medication or if an excessive dose of ibuprofen was taken, higher levels of the drug may remain in breast milk. Additionally, if the baby is particularly sensitive or has conditions such as impaired liver or kidney function, the drug components may affect the infant’s health through breast milk. In these situations, breastfeeding is not recommended, and nursing should be temporarily stopped until the drug is fully cleared from the body.

While using ibuprofen, it is essential to follow a doctor’s instructions regarding dosage and timing of breastfeeding; self-adjusting the dose or schedule is not advised. During any interruption in breastfeeding, a breast pump should be used regularly to empty the breasts and prevent milk stasis. Closely monitor the baby for any unusual symptoms such as excessive crying or diarrhea, and seek immediate medical attention if these occur. Women who have a known allergy to ibuprofen should not use this medication during breastfeeding.
