Hello, 

Diploma in Pharmacy certificate holders may start practicing as pharmacists in India. They may work at drug stores in Government hospitals, private hospitals, clinics, community health centres or private drug stores. In such a work setup, they usually check prescriptions (made by the Doctor), dispense drugs to patients, give them advice & directions, keep stock of drugs in storage, keep accounts and maintain the inventory.

Other than working for hospitals or private drug stores, D Pharm certificate holders may even start their own private drug store

Hope this helped. 

Good luck!
