Is it ok to take antacid tablet after drinking beer? Once I had couple of large beers. After that I've got acidity.
So Is it OK to take antacid tablet after drinking beer?
It depends... I don't see an issue with the standard Tums or Rolaids but there might be issues with ranitidine according to some studies.

  "The effect was striking," says author Charles Lieber, MD. In a
  three-hour test period, conducted under conditions similar to social
  drinking, the study showed that ranitidine can increase blood alcohol
  content by 38%. Levels reached in the study exceeded the legal
  drinking limit -- and the effects lasted up to two hours after
  drinking stopped.
