How to check the authenticity of drugs on the official website of the State Administration of Pharmaceutical Products?

1. After entering the website of Food and Drug Administration, we click to enter the "data query" sub-column under the "information disclosure" column on the home page. 2. After entering the query column, if you don't know which option to select for query, you can use "Advanced Query", in which you can check one or more of the approval number, trade name and production unit of the drug to be verified. 3. The batch number of each conventional drug is unique. For those health care products produced with the batch number of Wei Jian and counterfeit drugs produced with the batch number of others, we only need to check the batch number of the Food and Drug Administration and compare the batch number in the results with the manufacturer's situation, and we will know whether it is true or not.
