When you have a bad cold, you need to actively treat it with medication, and it is difficult to recover on your own. If you have a stuffy nose or runny nose, you can use cold medications, such as Senso-Kang, Vitamin C Yin Qiao tablets or Aminogalactone capsules for adults. For children, you can use Banlangen granules and pediatric aminophenol pseudo-lax dispersible tablets for treatment, which are more effective. If the symptoms of sore throat occur, adults or children need to take oral anti-inflammatory drugs, and the more commonly used ones are Pudilan Anti-inflammatory Oral Liquid or Blue Scutellaria Oral Liquid. If coughing and phlegm occur, anti-infection treatment is needed, and cough expectorant drugs are also needed. Anti-infective drugs need to be given according to the type of infection, appropriate antibiotics or antiviral drugs for anti-inflammatory.
