Safr to take xantac after having tums (calcium carbonate)? Any good heartburn remedies?

Tums (calcium carbonate) are an antacid (chemically neutralizes acid) Zantac (ranitidine) PREVENTS the effect of acid by blocking the RECEPTOR sites and finally PRILOSEC and other :Purple pills stop the release of acid altogether! They can be taken together AFTER a complete evaluation by your Primary Care Provider/Gastroeneterologist! since heartburn bad enough to require more than ONE of these needs diagnostic study! Hope this help.
