yo, not posted in a while. My opinion is that antacids DOES have an effect on reducing redness IF you take it with famotidine. Here is why.
I read on wiki that when you take generic famotidine such as Pepcid AC, it is absorbed into the walls of our stomach, but it is only about 50% (or less) efficient. However, if you take an antacid with the famotidine, it increases the absorption efficiency and therefore increasing the productivity of famotidine. We have all known for some time that Pepcid AC reduces redness but no one really knows why. By taking an antacid with it, it should increase its effectiveness in hiding the glow - that is according to wiki!
http://en.wikipedia.org/wiki/Famotidine read the last paragraph in "History and Development"
Over the counter stuff such as Pepcid Complete falls into the catagory of drugs that contain both famotidine and antacids.
I live in the UK and we have PepcidTwo which is a combo drug containing 10mg famotidine, 800g calcium carbonate and 165mg magnesium hydroxide. I also got some Pepcid AC 20mg famotidine off ebay.
MY EXPERIMENTS:
1. I've been taking PepcidTWO for a while now. It worked worked great for the first year. I could drink as much and as fast as I wanted and all I got was a very slight glow when it would otherwise have been red hot. Its effects started to wear off after about a year.
2. Started taking Pepcid AC on its own 20mg famotidine. It was ok, masked the redness but only when I drank slowly. Any huge gulps would cause the redness to show.
3. Recently, started taking one PepcidTwo and one Pecip AC. Works better when taken together than taken separately - for me anyway.
It would be interesting to hear what other ppl experiences are with the combination of famo and antacids.
