Requirements for production of an Over The Counter product?

Hello all,

I will need help to direct this posting to a more suitable topic category, I apologize.

May someone shed some light on the type of certifications/general requirements to pursue the production of an Over The Counter product?

Thank you 

PD it might help if you tell us what kind of product, lawn mower, lollipop? :smile:

Many thanks,
Simon

What is the product - supplement, drug, etc.

This would be an over the counter cough syrup.
