I Took My First Dose Of Ibandronate Sidium 150mg Saturday

I took my first dose of Ibandronate sidium 150mg saturday morning and 4 days later am still having side effects, pain right side then moved to left, much belching, back pain, it all comes and goes. My Dr put me on omeprazole, which I have now taken for 2 days. Symptoms seem to be lessening slowly. Is there something I can take to get this out of my system and how long is it possible for me to have these side effects.
