this is actually not common. i looked at the literature to see if there was any type of drug interaction and there is not. i would advise calling your health-care provider and letting them know that you are experiencing symptoms of gerd they may want to see you to re-evaluate. they may order a blood test to see what your level of vitamin d is.
i have gerd and take prevacid. my symptoms have exacerbated since taking a vitamin d prescription. is that common?
