1. There must be a drug approval number (X * * * * * *) X on the outer packaging of the drug you bought, which stands for English letters, usually H, chemistry, Z, Chinese patent medicine, S, biological agents, B, health care drugs, etc. You can query the drug by entering the approval number.
2. You should also query by entering the generic name of the drug.
3. When you know the network information of the drugs you bought, you can compare the drugs in your hand with the network information, including the approval number, generic name, chemical name, manufacturer, production address, specifications, dosage form, etc.
If they are all the same, you should be relieved. If there is a difference, there is probably a problem.
5. Comparatively speaking, I personally think the approval number, dosage form and specifications are the most important.
What's more, you must go to a regular hospital pharmacy or a regular pharmacy to buy medicine. If it is a pharmacy, you have the right to ask him to show your drug business license before paying. You should carefully check whether the license is within the validity period. If the pharmacy refuses, don't buy it.
Finally, if you are worried about the quality of the drugs you buy, you can complain to the drug supervision department in the place where you buy them.
Answer, you didn't buy medicine! ! !
You bought health food!
Health food is still prepackaged foods after all! Don't be a medicine. There will be no "functional label" on any health food package, only "suitable for people". The quality problem of health food belongs to the food and drug supervision and management department. If you are not at ease, you can also complain to the local food and drug administration!
