Antiviral Oral Liquid belongs to the class of drugs for clearing heat and detoxifying the toxins, and its main ingredients contain Panax notoginseng, gypsum, rehmannia, raw groundnut, yujin, Zhimu, calamus, patchouli and forsythia. The drug is widely used as a proprietary Chinese medicine for the treatment of influenza and wind-heat colds, although the safety of the drug is better and the ADR labeling in the drug instructions of the drug is not yet clear. However, all kinds of traditional Chinese medicines have their own taste and meridians, and this drug is mainly used for clearing heat and detoxifying toxins, which is cold in nature and not suitable for people with a cold spleen and stomach. The use of proprietary Chinese medicine preparations can easily lead to various adverse events if the nature and taste do not match or if the function of the drug is not accurately grasped. Remember that the drug is indicated for wind-heat colds, which are characterized by fever, slight wind, sweating, thirst, runny nose, sore throat, cough and yellow sputum. It should also be used with caution in patients with allergies. Consult your physician or pharmacist during use, avoid smoking, alcohol, spicy, cold, greasy food, and do not increase the dose to be on the alert for adverse reactions.
