Yes that's a symptom & is why it must be taken sitting upright or standing & full glass water nothing else before after for about an hour I believe. Correct me if this is wrong.....

When I take the Fosamax because you have to stand , I take a shower than dry my hair and that takes about an hour, then I eat

You must take it with a full cup of water and stand up or sit up DO NOT LAY DOWN the medicational is known for causing esophagus damage

why dont you on' get Prolia. Its so much better then subjecting yourself to medications that you take orally and getting gerd. I am wondering, too if the meds I have been taking, for Blood Pressure, Losartan, and now on Amlotapine. I read that Arbs, and calcium channel blockers can also cause gerd. I have an appointment today with the cardiologist to switch blood pressure meds. Please Lord, let him give me something that agrees with me!!! you really have to be your own avricate. (sorry spelled that wrong) but you know what I mean. You have to look out for yourself!

I have acid reflux & recently stopped taking painkillers which quelled symptoms. This drug isn't suitable for us all. Please read finer details on NHS website & make sure it is suited to you. There are other options for those who suffer like you.
