2. Log on to the website of the US Food and Drug Administration /WS0 1/CL00 1/, and enter the approval number in the data quick check box for inquiry (drugs and health products are classified, please pay attention to the selected category). If you don't have this number, it must be counterfeit. If there is a serial number, you can check the manufacturer and other information.
3. Look at the company name and contact information. If there is an approval number, you can consult the manufacturer whether it has produced this batch of drugs according to the online contact information of the National Bureau. If not, it's fake.
The next step is to judge according to the name and appearance of the product. This is a bit long and too professional, mainly to understand the naming principles of drugs (don't use exaggerated, boastful and unrealistic terms. Such as "Bao", "Ling" and "Jing", the names must not contain flattering words such as "imperial system", "secret system" and "refinement". Protecting animals should not be named. ), you can read the "Regulations on the Administration of Drug Instructions and Labels" in detail to understand the regulations on drug appearance.
5, see the functional indications and indications. The written expression of drug instructions and labels should be scientific, standardized and accurate. Instructions for over-the-counter drugs should also be expressed in easy-to-understand words, so that patients can judge, choose and use them themselves. It's suspicious to say something too magical.
6. Look at the way of packaging. If the specifications and packaging specifications of the same drug produced by the same pharmaceutical manufacturer are the same, the contents, formats and colors of the labels must be consistent; If the drug specifications or packaging specifications are different, the labels shall clearly distinguish or indicate the specifications. You can use this method if you often take the same medicine with the same approval number. Drugs that are often taken suddenly appear to have the same packaging appearance but different details or different feel, indicating that there are quality problems.
7. Check the external label for any suspicious words. Drug labels shall be subject to the instructions, and their contents shall not exceed the scope of the instructions, and shall not be printed with words and labels suggesting curative effect, misleading use and improper promotion of products. Drug labels shall not be printed with the words "exclusive sales in xx province", "original authentic products", "imported raw materials", "well-known trademarks", "patented drugs", "exclusive distribution in xx region" and "general agent in xx region".
The latter four methods are more professional. If you don't want to buy fake drugs, the easiest way is not to believe the contents of advertisements easily and buy drugs through formal channels. It is definitely not enough to buy drugs by mail or home delivery.
