Natural?: It is not a common natural function to block normal function(as most meds do) it is more natural to support normal function. Changing diet, adding fruits and veggies, and adding digestive enzymes and probitoics can all help reflux. ...Read more

H2 blockers can be used together with antacids?

H2 blockers can be used together with antacids?

Of course: H2 blockers (tagamet, zantac, (ranitidine) pepcid) reduce acid production, while antacids (mylanta, maalox) neutralize acid that has already been produced. Talk to your doctor about stepping up to proton pump inhibitor treatment to achieve improved acid suppression, if clinically warranted by persistent acid-related symptoms refractory to the combination of h2-blockers and antacids. ...Read more

I heard about the side effects of prolonged use of PIP's & was wondering if H2 blockers r any better 4 someone who had bleeding ulcer thats inactive?

Better tolerated: H2 blockers don't seem to have the same degree of effects like increased risk of osteoporosis, hypomagnesemia(low magnesium) and pneumonia as do PPI's. Remember, they both lead to lower levels of acid secretion, so you still have to have some concern of similar affects in the long run. ...Read more

I have chronic urticaria. What can I do? I heard that h2 blockers can help.

I have chronic urticaria.  What can I do?  I heard that h2 blockers can help.

Many meds for hives: H2 blockers are easy and inexpensive to try and they do sometimes help with treating chronic urticaria. They include cimetidine, ranitidine, Famotidine and nizatidine. They are all available over the counter without a prescription. In my experience, they rarely work well by themselves, but sometimes work well along with a good h1 blocker, like Cetirizine or fexofenadine. Use an allergist for help. ...Read more

Is one class of acid blockers generally considered more safe for long term use? PPI vs H2 Blockers specifically.

Is one class of acid blockers generally considered more safe for long term use? PPI vs H2 Blockers specifically.

No clear answer. As: with all medications, the big issue is not the medication but the situation; the dominant issue. Being alive is fantastically complex. Rx meds are only single molecules recommended in specific quantities/time to shift behavior, hopefully toward better. Stomach acid production can vary a million fold/24 hr, pH 7 to pH 1. H2 blocker can ? acid 100 times; PPIs 1,000 times ? of the million range. ...Read more

Why would reactive gastritis be seen on endoscopy if low acid diet and h2 blockers are the norm? What other recommendations are there?

Why would reactive gastritis be seen on endoscopy if low acid diet and h2 blockers are the norm?  What other recommendations are there?

Gastritis causes: Gastritis (inflammation of the stomach) can be caused by excess stomach acid associated with smoking, alcohol or caffeine. Gastritis can also be due to anti-inflammatory medications (nsaids) e.G aleve (naproxen), motrin/advil (ibuprofen) and others. Another cause: bile reflux after gallbladder removal. Diet has a minimal role and h2 blockers may need to be upgraded to ppi (prilosec, prevacid). ...Read more

Prilosec10yrs+ Short seg Barrett's.HALO ablation2015.Barrett's gone.Prefer stop PPI's. Endoscopy July '16. Wait? H2 blockers enough? Combo approach?

Endoscopy: I would wait for July's endoscopic results before making any changes in your management. If there's no sign of Barrett's, your gastroenterologist may agree with avoiding more long-term ppi therapy in view of recent reports of adverse potential side effects. On the other hand long term ppi treatment does protect against malignant transformation. ...Read more

What is the likelihood of missing h-pylori on various tests 2-3 times? For the breath test I didn't use PPIs or H2 blockers for 1 week prior.

Tests for H. Pylori.: Granted, some tests are more accurate and reliable than others, but most tests repeated three times should have sufficient accuracy to give us confidence in a negative result. That being said, the EGD with biopsy would likely be the most definitive. ...Read more

Small meals: Small frequent meals, low in fat and fried foods- cause they delay stomach emptying. Foods that dont contain caffeine such as coffee and tea and dark chocolate would be helpful since these products also increase acid production in the stomach. If overweight, losing weight can decrease the pressure on the abdomen that is contributing to reflex. ...Read more
