Sale of expired product

You can take resort of consumer court.

Thank you.

Since shopkeeper sold you expired date product and refused  to replace the same so  such act of shopkeeper amounts to his unfair trade practice and for which he is liable to compensate you.File complaint before District Consumer Commission and claim not only cost of product but also compensation towards mental and physical agony. 

Unless the cash memo reflects the batch no. , mfg. date and expiry date on the body of the memory you won't be able to do much. Suggest always to purchase medicinal products who does ethical business. 

It is true that you can move to the consumer court but you can prove from the documentary evidence about the authenticity of the particular medicine from the particular shop. Instead the dispute will continue 

Raise the complaint to food and drugs authority of India at your district. Don't forget to submit proof of the package clearly showing expiry date.

The consumer can register the grievance with the drug controller of the state and can also approach the Drug Controlle General of India.

Additionally:

If a pharmacy has sold you expired medication, the following legal steps can be taken: Report the incident to the state board of pharmacy: Contact the state board of pharmacy in the state where the incident occurred and file a complaint. The board will investigate the incident and take appropriate action if necessary.
