Doctor's answer:

Hello: Do not use antibiotics casually for children's colds.
Since most colds are caused by viral infections, antibiotics are ineffective against viruses, so antiviral drugs must be used. Commonly used antiviral drugs include:
1. Ribavirin: 10–20 mg per kilogram of body weight per day, taken three times a day, or 10–15 mg per kilogram of body weight per day by intramuscular injection or intravenous infusion.
2. Isatis root granules: Half a bag each time, three times a day, taken with boiling water.
3. Dipyridamole (Persantine): 5–25 mg per dose, twice a day, orally.
The above drugs can be selected as appropriate, with reliable effects and minimal side effects.
