What are the symptoms at the onset of a cold? Generally, at the initial stage of a cold, we definitely experience symptoms such as a runny nose, nasal congestion, low-grade fever, and slight coughing. If it's just a runny nose and nasal congestion, in this case, we can take some antiviral medications, some proprietary Chinese medicines, and also provide some acetaminophen chlorpheniramine granules to relieve these symptoms of runny nose and nasal congestion. If there is a cough, appropriate cough suppressant medication can be taken orally. At the same time, pay attention to body temperature; if there is a fever, fever reduction measures should be taken. If it is a low-grade fever, physical cooling should be the main approach. If the body temperature exceeds 38.5 degrees Celsius, oral ibuprofen or acetaminophen can be administered. Also, pay attention to the child's mental response and other conditions.
