The usefulness of taking cephalosporin for a cold with a sore throat and runny nose is related to whether the cold is combined or secondary. Colds are caused by viruses, and it is useless to take cephalosporin for simple viral infections, but cephalosporin is effective if combined with or secondary to bacterial infections. 1. Viral infection: colds are acute upper respiratory tract infections caused by viral infections, which can cause sore throat, nasal congestion, runny nose and other symptoms. Cephalosporin belongs to the β-lactam class of antibiotics, which usually has no effect on viral infections. This condition can be treated symptomatically to relieve symptoms. 2. Combined or secondary bacterial infections: bacterial infections can be directly infected or secondary to viral infections, in this case, taking cephalosporin may have a certain effect, but it is recommended that patients do not abuse antibiotics, and should be taken appropriately under the guidance of a doctor. Alcohol should be avoided when taking Cephalosporin. Cephalosporin may also cause allergic reactions, in which case the drug should be stopped immediately. Cephalosporin should be used with caution in patients with liver or kidney insufficiency. Patients are advised to take the medication under the guidance of a doctor.
