Women should avoid using drugs during breastfeeding because they may be secreted through breast milk and affect the baby. If a woman has a high fever during breastfeeding and the effect of other methods of cooling is not obvious, she can drink acetaminophen drops to reduce fever under the guidance of her doctor, but she must strictly grasp the indications and should not take the drug casually. Acetaminophen drops are non-steroidal anti-inflammatory drugs, mainly for fever caused by the common cold or influenza, but also to relieve mild to moderate pain, such as headache, joint pain, toothache, dysmenorrhea, muscle pain, neuralgia, etc.
