Introduction
Lianhua Qingwen is primarily used to relieve symptoms associated with COVID-19. If symptoms such as sore throat, cough, or fatigue persist after fever subsides, taking an appropriate dose may help eliminate residual pathogens and promote recovery. However, if there are no significant discomforts after the fever resolves, or only mild fatigue remains, continued use may increase the body's burden. Moreover, this medication is not intended for preventing relapse, and excessive use provides no additional benefits.

Generally, after recovering from fever due to COVID-19 infection, if symptoms such as sore throat and cough persist, medication can be taken under medical guidance. However, if there are no symptoms or only mild ones, continued use is unnecessary. If in doubt, it is advisable to consult a healthcare provider in advance. Detailed analysis is as follows:

Lianhua Qingwen is primarily used to relieve symptoms associated with COVID-19. If symptoms such as sore throat, cough, or fatigue persist after the fever subsides, taking an appropriate amount may help eliminate residual pathogens and promote recovery, especially accelerating improvement when symptoms are noticeable.

However, if there is no significant discomfort after the fever resolves, or only mild fatigue remains, continued use may increase bodily burden. Moreover, this medication is not intended for preventing relapse; excessive use provides no additional benefit and may impair digestive function.

Medication should be based on individual symptoms—do not blindly extend treatment duration. Monitor your body's response during use, and discontinue immediately if adverse effects such as diarrhea or nausea occur. Individuals with special constitutions or underlying medical conditions should seek professional medical advice before use.

Lianhua Qingwen is a traditional Chinese medicine formulation with functions of clearing away epidemic toxins, relieving toxicity, promoting lung dispersion, and alleviating heat. It is indicated for influenza characterized by lung invasion due to heat-toxin syndrome.

How long after taking Lianhua Qingwen Granules can I breastfeed?
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.
