When should I start Entereg?

I'm considering starting a new medication called Entereg, but I'm unsure of the right time to begin taking it. Can you provide some guidance on when is the best time to initiate Entereg therapy? Are there any specific conditions or factors I should consider before starting the treatment? Additionally, are there any potential side effects or interactions with other medications that I should be aware of?
