You should not take deworming medicine during breastfeeding because it can cause adverse effects to infants through breast milk. Since infants and young children’s liver and kidney functions are not well developed, if they consume milk containing deworming drugs, it may affect their liver and kidney functions, so it is not recommended for breastfeeding women to take deworming drugs. Commonly used worming drugs include albendazole, mebendazole, levamisole, piperazine citrate, etc. The most commonly used is albendazole, mebendazole, levamisole and piperazine citrate. The most commonly used is albendazole, i.e., intestinal wormer, which is broader spectrum and has relatively lower side effects. However, it also has certain side effects, mainly on the liver and kidneys, and can cause headache, dizziness, insomnia, as well as nausea and vomiting. Therefore, pregnant women or nursing mothers should not take wormer, and children under two years old are not recommended to take wormer.
