The reason why babies have drooling during a cold is that the cold often leads to more serious laryngitis, and children have a more painful throat, so they tend to be less likely to swallow saliva at this time. Effective anti-inflammatory treatment of the throat can relieve the symptoms of drooling caused by a cold in babies. If there is no pus in the throat and it is only slightly inflamed, you can use Pudilan Anti-inflammatory Oral Liquid, Blue Scutellaria Oral Liquid or Four Seasons Anti-viral Compound to give your baby anti-inflammatory treatment. If there is pus in the throat, it is best to use antibiotics for anti-inflammatory treatment. If there is no allergy to penicillin, you can use intravenous penicillin or intravenous cephalosporin antibiotics, which are also more effective. If the child has a serious cold, accompanied by a serious fever, the child must be hospitalized for treatment, especially if the temperature is greater than 38.5 degrees, it is easy to lead to febrile convulsions, which is very dangerous.
