gman524. Good questions.
Yes a fat meal of rich sauces, whole milk buttered puddings, whole milk ingredients, cream cheese, cream loaded chocolate cake etc, such as at holiday times of Thanksgiving etc. is extremely dangerous on the digestive systems.
The taker of the IR Opioids must take responsibility and not take the IR opioids at this time. IF HOWEVER they are in pain with a bad back, torn cartilage etc., then the Direction Instructions would instruct to open the capsule and sprinkle on apple sauce otherwise the Oxy will be delayed 2 to 3 hrs before absorption. It is up to the patient to be aware of this exact situation.
For ALL IR opioids it is ALWAYS best to
"Swallow the pill one hr before a meal or two hrs after a meal"
