hopefully when you take zantac or pepcid over-the-counter type of h2 blockers you should feel some relief within 30 minutes to an hour. so once again if you don't feel like it's helping then you could also take possibly an antacid like a maalox or tums or mylanta that would be okay. but if you find that that's still not helping in some cases you may need to be referred to a physician or a healthcare provider to have it looked at further. you can try one and of course the antacid may have a quicker effect because of the fact that its a liquid. so it doesn't take as long to dissolve as compared to the tablet.
how long after i take zantac will i begin to feel relief?
