Hi aspirants

Some state authorities has a requirement of 18 months work experience of production or quality testing of schedule c drugs while some of the states do not have this requirement any experience.

It is possible to become drug inspector even after B. pharm after clearing exam.

you have to check your respective state for  eligibility before applying it.  To become a drug inspector, candidates are required to go through a selection process conducted by the UPSC and/ or SPSCs.  The recruitment to the position of Drug Inspector is conducted by UPSC and also various state PSCs on an annual basis.

Hope this Helps

Good Luck!
