Why do you have to take some prescription medicines on an empty stomach?

Question

What happens if you take a medicine that should be on an empty stomach with food?

Answer 1

Medications all have different ways of being absorbed into your bloodstream, and if you take them with food when you are supposed to take them on an empty stomach, it might take longer for them to disseminate and will only be partly effective. It's along the same reasons that some pills are supposed to be taken at the same time every day-- because their make-up means they will stay in your system for X period of time, so if you take it sooner or later than you are supposed to, then you are having too much, or letting it out of your system completely.

Hope this helps!
