Omeprazole and stomach cramps

After reading all of the comments, I am embarrassed to say that I have taken omeprazole for the past 2 years. Originally, I began taking it for nausea from GERD. I began taking it soon after the death of my cousin (as I figured the anxiety from her death caused my stomach issues). I began to become depressed shortly after, which I also attributed to her death, financial issues, etc. However, when life got better I was still depressed and anxious. Two years passed and I still couldn't figure out why I felt so bad mentally. Not to mention I was mildly nauseous most of the time and NEVER had a normal appetite. I would only know it was time to eat when I felt faint. Light-headedness, stomach cramps and lethargy were also side-effects that I experienced almost daily. The worst part was that I didn't know if the nausea was caused by my stomach issues or by the omeprazole. It was obviously the omeprazole. About 2 months ago I switched to Prevacid which caused much less nausea but many of the other side effects were still there although a little less. I weened myself off completely (which I would recommend to anyone) and I actually feel like my old self again mentally and physically. I didn't realize how low my energy was until this last week that I've been off those meds. I'm actually HAPPY again, I WANT TO EAT something, I have ENERGY, and no light-headedness or stomach pain at all. It saddens me to think that I spent over the last 2 years feeling this way needlessly and thinking that I was crazy. There ARE other alternatives to acid reflux, GERD, etc out there that are much safer and more tolerable. If any of you are experiencing some of the symptoms that I or others have described, explore other options before you just "get used to" feeling like crap.

I have been taking Omeprazole 20 mg timer release tabs for 7 days now,
I am always tired, sever stomach cramps, sever gas, and diarrhea, and sometimes dizzy. I have decided to stop taking it at this point I have enough trouble eating I don't need more or what I do going right threw me. Thank you all for letting me know your symptoms are so I knew it was not just me. I wish you all the best of luck.

I have been taking Omeprazole since December 2007 now so 2 and a half months.

I had the dose increased to 40mg 3 weeks ago as 20mg wasn't curing the burning in my throat.

For a few weeks now i have had increasing vertigo/dizziness and palpitations. I only linked the 2 to the medication just yesterday, googled it just now and confirmed my suspicions to the Omeprazole.

Other feeling i have had since taking this medication...

Severe dizziness
vertigo
palpitations
headaches/migraines
weakness
fatigue
sweating
nausea
bloating
stomach cramps
visual problems
intolerance to bright lights
aching joints
chest pain

Now my question to myself is do i come off the tablets and endure the misery of my acid reflux? surely there must be something else we can take for our stomach problems that don't cause these awful side effects.
Anyone tried anything else that worked and didn't make them unwell?

My nine week old son has been on this drug for 3 weeks due to reflux. He suffers from lengthy bouts of crying, incredibly bad stomach cramps, raspy throat, constant sneezing, diarrhea. The reflux was easier to deal with than the side effects of this drug

I have been taking OMEPROZOLE for around 9 months for Barretts Asophegus reflux.
In general I was beginning to feel I was very ill with symptoms mainly: hot flushes, my face was burning for a few seconds, dizziness, stomach cramps top right mainly, feelings of diareah, and dry mouth.
Has anybody else experienced any of these symptoms... my GP is sending me for a scan on my Gall Bladder, but in my mind all these cramps are associated with Omeprozole... I cannot stop taking it or I get severe pain between my shoulder blades with reflux burning.

I have been taking Omeprazole for about 2 months and since the start of taking it I have had stomach cramps that range from slight discomfort to buckling pain that is almost unbearable, my hands and feet swell weekly and it was substantial enough for my wife to notice without question, also I have been experiencing nausea more frequently and more severe the longer I continue to take the medicine, I have occasional joint pain most often at night making it sometimes impossible to sleep, I've struggled with depression before and am not sure if the medicine is causing it or not but my wife says she has noticed a change in my attitude since being on Omeprazole, As far as other side effects I have developed a rash on my inner thigh that seems to coincide with starting the medication, also I have had sharp headaches behind my eyes probably about twice a week lasting anywhere from ten minutes to half the day

I have been taking OMEprazole for approximately 2.5 months and recently I feel dizzy to the point I want to get a doctor appointment to have an MRI or CT scan on my head - my fear is that I have a brain tumor. I feel dizzy as if I am going to pass out, occassional sharp pains in my head and I feel sick to my stomach. I also feel extremely tired and recently like the left side of my body is weak.

I am going to stop taking Omeprazole today to see if this is the side effect of the medicine. Anyone have similar experiences. If so, how soon do they stop after you stop taking the medicine? I was concinced I had a brain tumor - not so sure now.

PS I am a very healthy 50 year old who is a marathon runner. Lately I have sucked on my runs due to exhaustion.

After taking prilosec for many years I was switched to omeprazole 20 mg. I did not have any problem with reflux while on prilosec, but I do now. I have also had my entire body become very itchy, but more especially the bottoms of my feet. I get stomach cramps, a very bloated feeling usually follows. My blood pressure has increased, and I get bad headaches. I'm going back to prilosec.
