Woman with heartburn, gallstones, PPI complication, take omeprazole

We know you are getting weary of reading about serious side effects linked to proton pump inhibitors (PPIs). They are among the most popular drugs in the pharmacy. They include dexlansoprazole, esomeprazole, lansoprazole, omeprazole, pantoprazole and rabeprazole. OK, you probably don’t recognize those tongue twisters. But the brand names are familiar: AciphexDexilantNexiumPrevacidPrilosec and Protonix. There’s a new PPI complication to add to the list of possible adverse reactions: liver cancer.

Another PPI Complication:

Proton pump inhibitors are powerful acid-suppressing drugs. They are widely used to treat a range of digestive problems: gastroesophageal reflux disease (GERD), heartburn, indigestion, acid reflux, stomach ulcers and to counteract NSAID irritation of the stomach lining.

Doctors don’t usually think of PPIs as having serious side effects. The FDA considers drugs like Nexium, Prilosec and Prevacid so safe that the manufacturers are allowed to sell them over the counter. No doctor necessary!

PPI Side Effects:

There is a growing list of adverse reactions associated with proton pump inhibitors. Many were not known when these drugs were first introduced. They include:

  • Kidney disease
  • Infections (C. diff, pneumonia)
  • Nutrient malabsorption (magnesium, calcium, zinc, vitamin B12)
  • Weakened bones (osteopenia, osteoporosis, fractures)
  • Heart attacks (vascular calcification)
  • Dementia (Alzheimer disease)
  • Blood disorders (iron deficiency anemia, thrombocytopenia)
  • Disturbances in the ecology of the gut (microbiome)
  • Liver inflammation (liver disease)

PPI Side Effects Continue to Scare Us To Death

A new PPI Complication: Liver Cancer

A recent analysis of data from two large studies suggests that PPI use is linked to liver cancer (Alimentary Pharmacology and Therapeutics, July, 2018). Liver cancer is frequently deadly, and rates have been increasing sharply in both the US and the UK (World Journal of Gastroenterology, Feb. 14, 2014; Gastroenterology, March, 2017).

The scientists did a case control studying comparing people with liver cancer to others who were healthy. They also reviewed data from a prospective cohort trial. People who used PPIs were about twice as likely to be diagnosed with liver cancer. The researchers write:

“Using data from two large population-based studies which differed in design (case-control vs prospective cohort) and method of exposure ascertainment (self-report vs prescription records), we found a consistent association between PPI use and liver cancer risk.”

They caution, however, that their analysis does NOT prove a cause-and-effect relationship.

Possible Mechanisms:

The authors offer some possible reasons for this PPI complication:

“The cause of the observed increased risk of liver cancer with PPIs use is unknown. If real, our findings are consistent with an experimental study which showed that PPIs can promote liver tumors in rats. Various potentially harmful mechanisms of PPIs have been proposed. In particular, long-term PPIs use can lead to hypergastrinemia which has been shown to have a carcinogenic effect, particularly on liver cells. Also PPIs reduce gastric acid secretion increasing the survival of various microbes in the stomach. The resulting bacterial over-growth could greatly contribute to the transformation of primary bile acid in the intestine to secondary bile acid and has been shown to impact upon the liver exacerbating various liver diseases in mice.”

The authors hasten to point out that the association between PPIs and liver cancer needs to be confirmed by other research. They go on to say:

“However, the widespread use of PPIs, and particularly their use without clear indication, and the high mortality of liver cancer highlight the need for further research.”

We doubt that pharmaceutical companies are lining up to perform such research. The FDA is not likely to require it. After all, the FDA has clearly signaled that PPIs are so super safe that they can be used without medical oversight. The agency hates to admit it might have made a mistake. That leaves the funding for such research up to governments. It remains to be seen whether the NIH will sponsor this kind of expensive study.

In the meantime, we caution patients to use PPIs only as intended. The label on OTC products like Nexium 24HR is quite clear:

Directions:

• adults 18 years of age and older
• this product is to be used once a day (every 24 hours), every day for 14 days
• may take 1 to 4 days for full effect

14-Day Course of Treatment

swallow 1 capsule with a glass of water before eating in the morning
take every day for 14 days
do not take more than 1 capsule a day
swallow whole. Do not crush or chew capsules.
do not use for more than 14 days unless directed by your doctor

Repeated 14-Day Courses (if needed)

you may repeat a 14-day course every 4 months
do not take for more than 14 days or more often than every 4 months unless directed by a doctor

    I read PPIs are not good for you, so I had my dosage reduced to 20 mg & now 10. I also have hiatal hernia. I cannot go away without 10 mg. However, a Dr I saw a few days ago said 10 mg is barely therapeudic. What are alternatives? A 14 week trial will not work. I need a lifelong alternative. Karen A , northern NJ

    I started recently with Prilosec OTC for 7 days for stomach discomfort, then went to Doctor to be on safe side. He prescribed the stronger version (40 mg) for a two-four week course of treatment to see if the discomfort went away. It seems to be helping although it has only been a few days. However, I’ve noticed since I started with the OTC that my stool seems much darker than usual. The doctor did a stool check for blood that was negative, so I’m wondering if others have seen this same thing using this med? I don’t remember seeing this in the list of side effects.

    I reversed my acid reflux symptoms by drinking alkaline water. We make it ourselves using baking soda and filtered water. It was a pleasant surprise to find out i can eat wheat products without having the gastro side effects of gluten.

    My husband takes Equate Antacid + Anti-Gas Chews at bedtime. The active ingredients are Calcium Carbonate, 750 mg and Simethicone, 80 mg. I didn’t see these ingredients mentioned. Are they also risky?

    I have been on daily PPI (Prilosec) for many, many years because of daily and massive heartburn. I eat right and not excessively. I am male at 5′ 11″ and weigh 158 lbs.
    The reason for the daily heartburn is because I have a hiatal hernia. The only thing that works for me is a daily PPI. I believe I am not suffering any medical consequences with this daily regimen, but that’s not to say that some effects might not appear later. What am I supposed to do? It seems there is no other alternative. If there is, I would like to hear it.

    What a nice “Cash Cow” the PPI drug is for the pharmaceutical companies that manufacture and sell it to unsuspecting medical providers, who then prescribe it for sufferers of GI disorders. So many people on this forum have written about how they have tried to wean themselves off this drug only to be plagued with severe rebound pain, and often find themselves reaching for that PPI bottle once again, like an addict.
    It is hard to fathom that during the testing of these drugs that none of the participants experienced this themselves.

    I have Barretts’s esophagus and a huge – doctor’s words – hiatal hernia. I really don’t know how I could live without PPI’s, though I certainly would if I could. This is a study that requires duplication. Personally, I’d just as soon wait until there is proof of the association with liver cancer before receiving alarms – especially since I have no choice but to take the PPI. I’d prefer it if you could research and publish information regarding alternative methods of addressing horrific heartburn.

      I have Barretts esophagus and was told that I must take a PPI for the rest of my life. I am extremely concerned about all of the serious side effects. Is there an alternative to PPIs under the circumstances. What about Zantac? I am very careful with diet.

    I am not a physician. I looked into PPIs when a physician recommended that I take Protonix for a Hiatal Hernia. Went AMA, and said, “No thanks.” So glad that I did. I love my own self protection activities. They, I believe, have kept me alive.

    I use baking soda and water, it usually gets rid of acid reflux for me.

      Nancy in N.C., what are the amount of water to baking soda? How do you take it and how often?

      Thanks.

    Ha. Take only for 14 days. If only doctors had followed this. I was put on Aciphex and never told to take for just 14 days. I took it for 11 years! Yes, years! As a result, I am stage 3 kidney failure!!!

    How to get off the PPI?? have a friend who has been on them for years. Can she ever get off them?

    Have tried all the suggestions for getting off these medications to no avail. The acid reflux is too strong. I tried doing it gradually and reducing the doses until I got to every three days. But then I caught a cold and it all fell apart. I have been on some sort of medication for the reflux for years and would really like to be rid of them. Don’t have an answer.

    Is it safe to use a Pepcid every night to prevent reflux?

      Pepcid is not a PPI, so the problems described in this post do not apply.

    I have cut down using PPI to 2-3 days per week – Fri&Sat, and sometimes Sun. I have had to cut out fried foods, milk chocolate, some tomato based sauces, and certain spices. However, I will treat myself to Tex-Mex on weekends, after being good on my eating habits during the week.
