In clinical work, we often encounter so many outpatients who inquire whether anti-inflammatory drugs should be used for colds. There are some patients who, after catching a cold, routinely buy anti-inflammatory drugs such as amoxicillin capsules on their own and take them orally. And there are some older patients who believe that a cold cannot be improved without oral anti-inflammatory drugs. Have you encountered these situations? Or do you often take anti-inflammatory drugs orally right after you have a cold? Let’s first understand the common illness of cold and flu. More than 95% of common colds are viral infections, and colds are self-limiting diseases, meaning that they can improve on their own without treatment for 5-7 days. Daily cold medicine is mainly used to relieve symptoms such as nasal congestion, runny nose, sneezing, sore throat and cough caused by cold. Since it is a viral infection, anti-inflammatory drugs are of no use at all, and oral anti-inflammatory drugs are also prone to cause side effects of drugs, and long-term oral intake is also likely to cause dysbiosis of normal flora in the body. So there is no scientific reason to use anti-inflammatory drugs for colds. There are also some patients, as long as the cold, require infusion treatment. In fact, the general cold does not need infusion treatment, unless the cold causes nausea and vomiting, can not eat, easy to cause dehydration and electrolyte disorders, this situation can be appropriate to supplement fluids and electrolytes. But not infusion of anti-inflammatory drugs! Of course, if the cold is complicated by acute sinusitis, pneumonia, this situation needs to be treated with anti-inflammatory drugs under the doctor’s orders. To avoid delaying the condition.
