I am having some nausea and stomach acid after VHL brain tumor surgery 1-8-14. Home now, couldn t find Mylanta in store, coulda I use Tums extra strength anti acid on occasion. Post surgery drugs are Ondansetron 4 mg 8 hrs PRN, I am tapering it off and have taken only 2 does in the last 36 hours. Also on Dexamethasone stepping it down too. Should I just forget about taking Tums, it warns of drug interactions thank you
