Can I return a drug I just bought from a major pharmacy?

Upstairs is right, there are provisions for drugs sold non-quality problems do not return, because after the sale of drugs, even if you do not open, but you can not prove that you buy drugs to return the time of preservation is reasonable and effective, that is, you can not prove that the quality of drugs is qualified, so the drugstore will not accept the return. Pharmacies sell drugs, as long as the formal channels, from production to stores to sell out between all aspects of the relevant legal provisions of the storage and transportation conditions, and to do records, such as the pharmacy to register the temperature and humidity every day, the operation of the equipment, etc. ...... These are all proof that the drugs are stored in the pharmacy in accordance with the regulations, that is, proof of the quality of the drugs. In order to ensure the quality of the drugs, the general drugs sold after the non-quality problems will not be returned. The relevant laws have provisions.
