You really want to think about and treat the pill the same way you do or would other medications:
• read the patient information that comes with your pill, and know that if it working is reliant on any specific conditions (like when you eat, how often you need to take it, etc.), that information is included. If something isn't there, it's almost always because it doesn't need to be.
• ask your prescribing physician or pharmacist any questions you have about it
• have faith that so long as you follow the most basic directions, it will be effective: after all, it has been studied enough to be prescribed (and the pill, specifically, is one of THE most studied medications of all time, so we REALLY know for sure that it does what it says), and it is in the self-interest of the company that makes it for it to work as directed.
So, check that pill insert (they are posted online by pill companies/manufacturers if you don't have a paper copy handy). Notice how it doesn't say anything about this, so know that's because this isn't a thing.
