An Erning and Ambroxol can be taken together, and there will be no reaction between the two drug ingredients and no adverse consequences. An Erning is a heat-clearing and detoxifying proprietary Chinese medicine containing artificial oxalis and other herbal ingredients, mainly used for the treatment of fever and sore throat and other upper respiratory tract infections, but it should be avoided by children suffering from serotonin, allergies to ingredients such as oxalis, as well as wind-cold colds. Ambroxol is a mucolytic agent, mainly used for children with thick phlegm, with the effect of removing phlegm, but it should be used with caution for children with weak cough reflexes, so as not to cause the risk of choking. If you need to use medication after your child is sick, be sure to take your child to a hospital pediatrician and use the medication under the guidance of a professional physician to avoid adverse consequences.
