If your boyfriend has a fever, the first thing you need to do is to take his temperature. If the temperature is below 38.5℃, you need to ask him what all discomfort he has. If there are symptoms of nasal congestion, runny nose and sore throat, it is a viral cold, and you need to give him antiviral drugs for treatment, such as Pudilan Anti-inflammatory Oral Liquid or Blue Scutellaria Oral Liquid, cold and fever clearing granules are also available. If the temperature of fever exceeds 38.5℃, you need to give him antipyretic medicine, such as ibuprofen suspension or acetaminophen suspension. Usually take 10ml at a time and use it no more than 4 times a day, and can be repeated once at an interval of 4-6 hours.
