PRILOSEC  (OMEPRAZOLE):  Omeprazole is used to treat certain stomach and esophagus problems (such as acid reflux, ulcers). It works by decreasing the amount of acid your stomach makes. It relieves symptoms such as heartburn, difficulty swallowing, and persistent cough. This medication helps heal acid damage to the stomach and esophagus, helps prevent ulcers, and may help prevent cancer of the esophagus. Omeprazole belongs to a class of drugs known as proton pump inhibitors (PPIs).   FDA Approval Date: 1998-01-15 (Sources: U.S. Centers for Medicare Services, FDA)

 2  acid reflux After about 5 days of taking Prilosec OTC I started to feel really dizzy, have light headaches, and fatigue. I figured I was coming down with the flu. After 3-4 more days, I still didn't have the flu, but I started feeling nauseated all day and having stomach pain at night. My muscles also started cramping very badly everywhere from my fingers to toes to abdomen to legs. I have PCOS and am therefore prone to magnesium deficiency and therefore muscle cramps, but I couldn't figure out what was causing them to suddenly increase so severely. Finally I looked up Priolsec side effects online and sure enough, magnesium deficiency (and all of these related symptoms) are common side effects. I stopped taking the Prilosec yesterday morning and started taking a magnesium supplement, but I am still experiencing all these symptoms. I wonder how long it will take to get back to normal. It does work REALLY well for curing heartburn/acid reflux, and I know some people who swear by it. But I think if you have any trouble getting/retaining magnesium or any conditions (such as PCOS) where this common you probably want to avoid it. The side effects are much worse than the acid reflux.

 2  little burn\sting on left chest loss of appetite, muscle tightness, stoach numness/tightness/cramp, fuzzy feeling and not as self consious - as if I was on a mild drug. headaches. major adominal tightness, nummness,odd feeling. mild constipation, weezing and inner ear\right eye pain\numness. Walked into a few doorways, feel like body stiffening up. mood change. birping for no reason and sometimes regurgitation while bending over to tie shoes. Thirsty the 1st 4 days and then not thirsty enough. 2nd day appetite gone, didn't even want snacks! felt chest muscles were tighter, 3rd day arm muscles felt pumped and stomach tight and sort of little pains all over from knees to neck. 4th day stomach really tight and num off and on. next day hurt to walk back of legs above knees, wierd feeling all over, teeth aches, ear ache, head ache, slight dizzyness. after 1 week stopped for 2 days and started to feel better muscle and appitite wise, but headache got worst. Started taking it again and headache getting better, loosing appitite, stomach and muscle cramps off and on that are little and sharp and all over. lower back pain for the last 4 days. NUM feeling energy wise, but a little spacy. I even went walking the last 3 days, but lacked my normal Hulkamania energy level. Soda and caffeen have little effect while on this for spiking energy like it did before. Wrists hurt today as if I was getting carpal tunnel, but I know it is the prilosec. I am always happy and full of energy. I eat junk food all the time. On Prilosec I became mellow and monotone. Could be because I eat almost nothing now unless I force myself to eat something. wierd feeling sort of like out of the body sometimes which seems to me is because vision is altered. I can see better and read faster since on this, but at the same time, my peripheral vision is way down, sort of like a mild tunnel vision. I'm 39 and was 241.5 a week ago. I am down to 229 today and dehydrated - I have to remind myself to drink water bec M 39 9 days

 1  Stomach pain severe back pain, neck stiffness, throat tightness and dryness i was prescribed this at the ER because they didn't know what was wrong with me. after a couple days of taking this it made my throat feel super tight like there was a rubber band around it. i wasn't having any difficulty breathing but it was very uncomfortable. my throat felt very dry too no matter how much liquid i drank. then i got severe back pains that kept me on a heating pad for the whole duration of the medicine. 4 days after stopping the medicine the back pain and stiff neck went away and my throat went back to normal. but it didn't help my stomach problem. i was still having the symptoms i had before the medicine. this stuff is poison.you feel worse than you did before taking the medicine!

 1  Acid Reflux Extreme weakness and fatigue, shortness of breath, blurred vision, muffling of hearing, diarrhea, bloating, anxiety, panic, feeling of dread/doom. Provoked an extreme flare of a chronic illness. I had one night of insomnia due to a sudden bout of regurgitation and my doctor suggested Prilosec. Nothing seemed out of the ordinary the first 6 days, but then all the sudden all the side effects set in and I've been mostly bedridden for the past 3 days feeling like I've been struck with the flu yet have no signs of an infection. I am chronically ill, but this is the worst flare I've ever felt since diagnosis years ago. Too sick to work for the past 2 days. Had to make a trip to the store to pick up something and had a major panic attack just driving there and felt like I was going to pass out in the store; not like me. Going to stop taking immediately today after reading all the similar stories here. M 32 9 days

 1  Heartburn High anxiety and depression. Brain fog and disassociation with reality. Muscle fatigue and shakiness I had no idea a ppi could make you feel this way. I hope since I only took it for a short while that these symptoms subside. I can’t work. I can barely eat. It’s awful. Please tell me this goes away. M 34 9 days

 1  For Acid Reflux (Severe) I was taking other medications (high blood pressure, Pain medications) and couldn't figure out what started causing my leg cramps and I had fallen and hurt my arm about a week before taking the medication for my stomach. Then I stopped the medication for my arm but had severe leg cramps, pain in my head pressure, fuzziness, tingling and burning in my arm and pain in my back upper and lower back. Not until I read other people symptoms did I figure this out. I was only taking the medication for about two weeks. It helped the acid reflux but the other side effects are horrible. F 50 9 days

 1  Acid reflux Aching kidneys, nausea, heart palpitations, buzzing/tingling sensation all over, insomnia, aggitation, dry mouth, paranoia, fatigue. After I stopped taking them the side effects became worse for a few days, the acid reflux also got worse. Finally after about 5 days I started to feel normal again. Will avoid in future and will concentrate on a dietary approach to treatment. F 39 9 days

 4  acid reflux, heart burn constant burping I have no problems other than the incessant burping, which is not normal for me. my eating habits have not changed, but suddenly everything makes me burp. not a big deal at all since the acidity is diminished and my abdomen feels fine, but it's strange to me.

 3  gastritis diarrhea, gas It seems to work great in reducing my stomach pain but after a few days into it, I began to have diarrhea, loose stool, and gas. Last evening, I had to go to the bathroom about 7 times, not much coming out except a small amount of mucous like substance each time. Then was ok until this afternoon.....same thing again with lots of gas. I had similar experience about 2 months ago when I took Prilosec for 14 days. I think I will stop and see of side effects go away. M 45 10 days
