Have acid reflux and hiatus hernia I have been prescribed rabeprazole 20mg, omeprazole 20mg and lansoprazole 30mg, which would you say was best?

All comparable: All of the PPI's (proton pump inhibitors) are very effective at reducing acid. Some keep the gastric pH <4 longer than others, but the bottom line, is which one works for you at the lowest dosage and the cheapest price. Check with your insurance company and find out which is their preferred drug. ...Read more

Basically same...: While you will hear anecdotal stories that one worked better for someone than the other drug, a number of randomized clinical trials (gold-standard for science) found that they were equivalent, both with respect to safety and efficacy.

On 30mg lanzoprazole and 10mg omeprazole. What are potential side effects?

PPI's: It is unusual for someone to be on two of the same class of medications at the same time. Was this prescribed this way or did you just take it on your own? Generally PPIs are relatively safe. Short term they have very few side effects. Long-term there are some concerns over kidney, electrolytes, and possible pneumonia risks. Talk to your doctor to manage this. Good luck. ...Read more

The same: Generally, PPI medications such as Prevacid (lansoprazole) and Prilosec usually do not have any effect whatsoever on bowel movements.

I started taking Plavix once a day and I also take Prevacid (lansoprazole) and on occasion Prilosec. Is there any interactions with these drugs?

Absolutely: There is a well know interaction between plavix and proton pump inhibitors. Plavix is a prodrug (inactive) and is activated in the liver. This process of activation is blocked by proton oump inhibitors. Specifically with nexium and prilosec, also somewhat with other ppis. The only one safe to use is dexilant (dexlansoprazole) and possibly protonix. Or change plavix to effient or brilinta under guidance of MD ...Read more

Is there any treatment for a double pylorus besides pump inhibitors like Prilosec and prevacid (lansoprazole). Need answers?

Is there any treatment for a double pylorus besides pump inhibitors like Prilosec and prevacid (lansoprazole). Need answers?

Usually no therapy: Most commonly a double pylorus is due to prior ulcer disease. If there is ongoing ulcer disease than a proton pump inhibitor (eg Prilosec or prevacid) is the standard of care. If you have ulcer disease, a test for helicobacter pylori should be done. If there is no ulcer than no therapy for the double pylorus is required. ...Read more

Meningioma, enchondroma, psoriatic arthritis & ankolysing spondylitis. Could any of these be caused by being on Prilosec or prevacid (lansoprazole) for 15 years?

Prilosec effects?: Prilosec and Prevacid (lansoprazole) are proton pump inhibitors that reduce stomach acid production. They are used to treat heartburn, stomach inflammation and ulcers. Recently there have been some reports that long term usage could increase the risk of osteoporosis (decreased bone density). I am not familiar with the drug causing any of the problems you have, however. ...Read more

Conservative rx: Be sure all conservative measures have been taken such as no eating after dinner, elevation of the head of the bed, avoiding greasy food, garlic, onion, stop smoking, lose weight. The addition of carafate and welchol may be of benefit, welchol binds bile acids, and carafate helps heal erosions. A short course of Reglan (metoclopramide) may help as it increases the tone of the lower esophageal sphincter. ...Read more

Is there any difference between PPI drugs like prilosec, nexium, (esomeprazole) prevacid, etc?

Not at all: No they are all, as you said PPI's and appear to provide similar relief. Some are more expensive than others and drug companies would like you to believe their PPI works better than the generic. It is my belief that in general, you should stick with generic medications. Do not fall for the marketing hype. ...Read more

Taken Nexium, (esomeprazole) generic Nexium, (esomeprazole) and Protonix which cause drowsiness. Would it be worth taking Prevacid or Prilosec? Will tired feeling go away with time

Taken Nexium, (esomeprazole) generic Nexium, (esomeprazole) and Protonix which cause drowsiness. Would it be worth taking Prevacid or Prilosec? Will tired feeling go away with time

Doubtful: None of the actions of any of these drugs would have anything to do with drowsiness. That is a very uncommon side effect of any of them. BUT
Prilosec is well known to gum up the liver's ability to get other drugs out of you including all sedatives including alcohol.... so. That one is doubly out.
Otherwise, while I cannot explain why these drugs do that on you, the entire group is similar ...Read more
