"3 years ago I was suffering constant diarrhea and the dr thought I might have an ulcer so while I waited on tests and having a scope I was put on omeprazole. While taking it I started having increasing abdominal pain and while it did stop the diarrhea issue, by the end of the second week the stomach pain was so bad I couldn’t keep taking it. I had severe cramps and bloating. Ever since then literally everything makes me burp or have gas, even water. I never had a gas problem before. I was only taking omeprazole for 2 weeks and my body has been messed up for over 3 years now. I almost always have cramping gas pains which I have to push my belly with my hand to move the pain around when it gets too bad. The doctor didn’t seem interested or didn’t want to believe me that this all started from the drug and has never gone away. I’m looking for another doctor but I fear that my digestion is messed up for life now. I wish I never took it."

"I had severe nausea and hunger pains, started taking Prilosec OTC, began to slowly help and my stool became a little off. Doctor said gastritis/GERD, 40mg omeprazole prescription, 30 days worth. Within a couple days it went downhill, every trip to the bathroom was terrifying, had strange color stool, strange texture, was so much undigested food and mucus I thought I had something else and was dying, not to mention the anxiety this medicine gave me was horrifying, would have insane panic attacks before bed, and every time the side affects hit I would nearly have a stroke my heart was racing so fast with nervousness. Various places in my stomach would burn and throb at various times, pain in my lower right abdomen and behind my ribs, I would have a sharp pain through my ribs and back that felt like all my organs were being destroyed right in front of me"

"I was prescribed omeprazole to help control my gastritis flare up, although it was never specified if all my symptoms were due to gastritis in the first place. Anyways, I took omeprazole and for about two days and I felt better. Now I have been taking it for a week and it seems all my symptoms, minus the diarrhea came back in full force. If anything I wake up normal and as soon as I take the capsule my stomach begins to go sour within half an hour and I have to deal with that all day. I can’t eat anything because it threatens to come back up with my random bouts of nausea. I will stop taking it tomorrow to see if it really is the medicine causing these side effects."

"It is really a bad medicine. The doctor prescribed my wife to use this for gas relief. but my wife was not comfortable after one pill. Her ears and nose were blocked and she could sense the skipped heart beat. I don't recommend this product."

"Second day of taking this medicine I felt chest pains and diarrhea few minutes after taking. It helped with my acid reflux and ulcer but, the chest pain and stomach cramps is mild compared to what was happening to me before I was prescribed this medication. I take two pills every morning once a day, I think I'll reduce the dosage to one pill, and will see how it goes. Yes there are side effects, but what I went through before taking this I couldn't live a normal life. Try changing your diet. Eat solid non spicy food for some time, no alcohol and acid soft drinks."

"I mean, I completely won’t knock omeprazole. It works. This is my second time dealing with gastritis and my second time taking omeprazole for it. Yes, omeprazole has side effects, and I know it’s from the drug because it’s been the same feeling both times. (Slight chest pain, trapped gas, dizziness, slightly elevated heart rate upon motion and general unwell feeling) however, when compared to the worst side effects I get from gastritis (no appetite, constant nausea, cannot eat, I get severe anxiety that comes with it) the ones from the omeprazole definitely don’t seem so bad. I take it until I’m eating normally again and my stomach has healed, then I discontinue it. Usually about 3-4 weeks. All I can say is, yes the side effects suck but everyone’s different. My grandmother has been taking it for years for GERD and has zero adverse effects. Give it a shot, the worst it can do is not work for you."

"Tried this stuff (omeprazole) for about a month, since doctor put me on it for acid damage in my stomach. First day I was minorly nauseous with it slowing building up more each day. For the past to weeks I have been waking up and vomiting for several hours even if my stomach is empty. Yesterday I was completely incapacitated due to the vomiting. Looked up side effect and saw nausea and vomiting so decided to not take it today and I feel 100% better. Will not be taking this again."

"I am having really strong side effects with these meds. I am not sure if they occur in the first few days. I can't take them during a working day as I get too tired. I have felt slight relief after taking them. I have chronic gastritis."

"I was prescribed omeprazole for ongoing nausea in 2021. After 3 months I was advised to stop it. It had worked brilliantly and I felt so much better. My symptoms re-occurred and I was advised to restart and referred for gastroscopy which I had in December and showed mild gastritis and duodenitis. Biopsies neg for helicobacter, to continue PPI for several months. Reluctant to get "hooked" on PPIs I am now ( nearly 3 months later) trying to reduce to alternate days, however the nausea persists on the day without omeprazole and GP suggests take daily and try again "in a few months". I have had no adverse effects but am concerned re possible blocking of magnesium absorption as I take this for heart arrythmia.."

"After trying pregabalin for nerve pain, it gave me gastritis and the most horrific reflux. I couldn't breathe. I started Omeprazole on the 7th of Jan 2021 and the reflux reduced within 2 days. I then bumped up to 40mg (20 twice a day) to help my stomach heal (on the 14th of Jan). During my time on it I've had some horrible gas and bloating with sharp pains in my groin and the feeling like I was going to have a horrible BM, but with nothing happening. I have IBS too which doesn't help. The main concern I have is the pressure in my groin that makes me feel like I need to pee. Reading down this page and I'm thinking Omeprazole is the cause of all these extra issues not gastritis. I kept taking it because the problems were still there, but thinking back they only started when I started the Omeprazole. I would highly recommend it for reflux, but stick to the 2 week warning. (I've had scans so I know it's gas)"

"I was prescribed this drug by an NP to treat gastritis, at 20mg daily for 30 days. I had been diagnosed with gastritis before and was told to take Pepcid daily and I had no issues with that. The NP told me the only side effect I might experience taking omeprazole was diarrhea. In reality, what I experienced was a massive increase in anxiety depression and nightly panic attacks. My resting heart rate has gone up about 20 bpm after taking omeprazole for just 20 days. I am unable to fall asleep until well into the morning so only 3-5 hours per night. I have had anxiety and depression for years, but never as intensely as it is now. I did not consider that the omeprazole was the cause of it! I started a new anxiety medication a little over a month ago and blamed it on my body adjusting to that- after reading these reviews I am almost certain the mood and sleep disturbances I am experiencing are due to taking omeprazole. The acid in my stomach is reduced but that could be my change in diet."

"Took this to take care of gastritis. I thought I had an ulcer, but luckily I didn't. I took it for about two weeks and then discontinued it. I will say it helped improve my appetite and eased the stomach pain. That being said, the second week I was feeling a bit out of it. Mildly anxious and just didn't feel like myself. I think it's good to treat an acute case of gastritis but not something I would want to be on for more than a week or two."

"I was prescribed omeprazole after being diagnosed with gastritis and over many years I have suffered with palpitations, terrible tightening in my stomach, night sweats with insomnia, aches & pains and nausea. Also had the paramedics out one evening and an overnight stay at the hospital as they thought I was suffering a heart attack. Every time that I have seen the doctor and said these symptoms were worst than the gastritis and not helping at allI have been told to carry on taking them incase the gastritis changed into an ulcer or cancer!! This has left me in a dilemma as I have already had my kidney removed (16 years ago) due to cancer. I have pondered over the years why I have been having these awful symptoms but was always told it was stress & anxiety! Having read these I now realise that it isn't just me that's suffering and it helps a great deal knowing that omeprazole is causing my problems - definitely not curing them."

"I had the worse gastritis where I could only curl up in a ball and roll. My back was on fire, I was nauseous, and it was horrible. Dr. did a GI test to diagnose. He put meet on our twice a day. I was fine and it definitely helped. No crazy size effects. But, it didn't help right away. What did help with the crazy burning in my stomach (felt like a lit match being put to my stomach from inside) was a mix of coconut oil and peppermint essential oil, mixed correctly obviously, and rubbed all over where my stomach was. Took about a half hour to stop the pain, but I couldn't believe it actually worked! I was desperate for the pain to stop so I tried the essential oil. I didn't want the Karen's to be right lol but this time they were! In the end I and thankful for that and the Omeprazole. Oh, , one more note .. my health insurance charged me more for the Omeprazole than it cost to buy at the pharmacy, can you believe that! So I ended up buying it over the counter the next time I needed it."
