Empty Stomach

It’s fairly clear what “take with food” means – not withstanding the details of how much, what types, etc. Much less clear is the instruction “take on an empty stomach.”

In short, “take on an empty stomach” means having nothing to eat for at least two hours before taking the medicine and then not eating for at least thirty minutes. The medication should be taken with a full glass of water (not juice or coffee). Two examples of medications that should be taken on an empty stomach are thyroid supplements and stomach acid blockers. Most people take these medications upon awakening; by the time they have finished washing and brushing a half hour has passed. Others are too rushed in the morning – taking the medication before bed is fine as long as there has not been any after-dinner snacking.


When in doubt, consult with the pharmacist. And while you are asking: are there any medications that should be taken at different times? It’s tempting to just swallow a handful of pills all at once but there could be interactions.
