Can i take reglan (metoclopramide) for the stomach flu?

Might back fire: Reglan (metoclopramide) is a prokinetic, meaning it makes the gut move faster. It can make it move faster one way or the other . So if you are having vomiting or diarrhea, it could make it worse. Reglan (metoclopramide) is used in folks whose GI tracts do not move well, ie delayed gastric emptying. If you have been prescribed this, then talk to you doctor. Don't every use something prescribed for someone else. Try probiotics.

Probably won't help: There are usually two phases to stomach flu. First, when vomiting, the gut just wants to shut down for a few hours and says" don't put anything in me right now 'cuz i'm just going to give it back". Reglan (metoclopramide) won't help here if the gut is shut down. The second diarrhea phase, the gut goes into overdrive to get rid of the virus from the "other end" and flush you out. You don't need to add fuel to fire.
