Introduction
It is recommended to wait 4–6 hours after taking Lianhua Qingwen Granules before breastfeeding. Lianhua Qingwen Granules contain heat-clearing ingredients such as Forsythia suspensa and honeysuckle. Although these are commonly used traditional Chinese herbs, some components may pass into breast milk and affect the infant, especially newborns who have relatively weak gastrointestinal function, thus direct drug exposure should be avoided. A 4- to 6-hour interval allows partial metabolism of the drug, reducing its concentration in breast milk.
Generally, it is recommended to wait 4–6 hours after taking Lianhua Qingwen Granules before breastfeeding. For individuals with mild symptoms, this interval may be shortened accordingly, while those with severe symptoms should follow medical advice. If in doubt, professional evaluation is advised prior to resuming breastfeeding. Detailed analysis is as follows:

If a breastfeeding woman has only mild symptoms such as slight sore throat or fatigue, the waiting time may be reduced to 3–4 hours after medication. However, if symptoms are severe or the infant is very young (under 3 months), it is advisable to extend the interval to more than 6 hours or temporarily suspend breastfeeding, resuming only 24 hours after discontinuation of the drug.
During medication, drink plenty of water to promote drug metabolism and maintain a light diet to reduce gastrointestinal burden. Closely monitor the infant's condition, and discontinue breastfeeding immediately if abnormalities such as diarrhea or persistent crying occur. Before taking the medication, ensure there is no history of drug allergy; if symptoms do not improve, seek timely medical consultation to adjust the treatment plan.
