"1. i can't find tagamet here, just Kremil-S which includes Magnesium Hydroxide 233 mg, don't know that it can be a good choice for antacid?
Otherwise, Milk Of Magnesium is the better choice for Antacid?"
Antacids containing magnesium hydroxide are considered to be a good choice.
So Mylanta or milk of magnesia may be good choices. Kremil-S may also be a good choice.
H2 BLOCKER / ANTACID :
Some people believe an antacid may be faster acting and more effective, but opinions vary. H2 blockers reduce the amount of acid your stomach makes, whereas antacid neutralises the acid already in your stomach.
H2 blockers : Tagamet (Cimetidine) / Zantac (Ranitidine), or supermarket own brands of cimetidine / ranitidine. Pepcid may also be suitable (though I haven't confirmed or researched).
Other options : Maalox, Rennie, Tums.
I'm not sure if Sodium Bicarbonate (eg Alka Seltzer), is a good choice, since it was removed from the peaceful pill handbook. The suitability of Gaviscon has also been questioned.
Note : As @Quarky00 states, they are not considered to be essential, and can be omitted.
