The appearance of a cold and runny nose. First of all, you need to observe the nature of the runny nose. If the nasal water is blue, it is often caused by viral infections, so it is better to use cold medicine for treatment or antiviral drugs for relief. Anti-viral drugs can be chosen from Pudilan Anti-inflammatory Oral Liquid, Blue Scutellaria Oral Liquid, Four Seasons Anti-Viral Compound, Ribavirin Granules. There are also more anti-cold medications to choose from. Adults can use Aminophenol Pseudo-anesthesia Dispersible Tablets, Aminga Flavin Capsules, Sensitive Health, Cold and Flu Granules or Vitamin C Yin Qiao Tablets. If it is a child, there are relatively fewer drugs to choose from, such as pediatric Banlangen granules, pediatric aminophenol pseudo-lax dispersible tablets, pediatric aminophenol xanthamine granules, pediatric cold and fever granules for treatment, which are all more effective. If the phenomenon of yellow nasal discharge indicates a bacterial infection, antibiotics can be used to reduce inflammation, such as amoxicillin can be taken.
