At present, there is no clinical research data on the use of Abidol hydrochloride in children under the age of 18, so it is not recommended that children use this drug, and the specific use of the drug should be in accordance with the doctor’s instructions. Abidolol hydrochloride is an antiviral drug used to treat upper respiratory tract infections caused by influenza A or B viruses. Currently, this drug is mainly used in the antiviral treatment of adults, and there is no clinical research data on the use of this drug in children in China, so it is not recommended that children under the age of 18 years old use the drug. However, it should be noted that some data show that this drug can be used in Russia for the treatment of influenza in children over 2 years of age, so the possibility of using Abidol hydrochloride in the treatment of pediatric patients in the future or under certain special circumstances is not completely ruled out. It should also be noted that the drug is contraindicated in people who are allergic to it, and there is a risk of nausea, diarrhea and other adverse reactions during the use of the drug. Therefore, those who have the need to use Abidol Hydrochloride, must be under the guidance of a doctor to regulate the use of medication, do not blindly use or increase or decrease the dosage of medication, in order to avoid adverse consequences.
