There is no such thing as the best treatment for a cold and runny nose, so this statement is not true. Cold and runny nose is a common clinical symptom. Viral infections such as rhinovirus, coronavirus and other viral infections cause progressive damage to the mucous membrane of the nose, leading to an increase in secretion and causing the symptom of runny nose. The common cold is self-limiting. If the symptoms are mild, it can be cured in about 1 week. If the symptoms are obvious, symptomatic treatment can be given. Theoretically, there is no specific drug treatment for viral infections. If the runny nose is severe, drugs such as loratadine and levocetirizine hydrochloride can be given symptomatically to help alleviate the symptoms of a runny nose. If necessary, with acetaminophen, cold and fever particles, can achieve significant results. In summary, the runny nose during the cold is self-limiting, if the symptoms are obvious, it is recommended to go to the respiratory medicine department of the hospital, under the guidance of the doctor, symptomatic treatment, which is conducive to relieving the symptoms.
