 3  GERD Sore throat, constricted throat, constipation, nervousness, anxiety, insomnia, interesting dreams, stomach pain. I have used this drug on and off for years. When I was in my 20's I took 300 mg. a day for about 3 months without experiencing any side effects. I have been taking 150 mg every day for about a year, with minimal side effects only a little insomnia here and there. I started experiencing stomach pain and did not think at all that the Zantac could be causing it, so I upped the dosage to 300 mg. After 4 day's at this dose I experienced a tightness in my throat, sore throat, agitation, insomnia and anxiety. I missed a day of work I could not function. I have had issues with taking medications in this class of drugs, I usually experience headaches, this is the one drug that does not do that. I have now stopped taking Zantac and have made an appt. with my Doctor. F 52 365 days

 4  H.Hernia/Acid reflux/Pain swollowin GP prescribed this as Rabaprazole caused heart arrythmia and Omaprazole caused itchy skin. First 7 days fine but little acid relief then OMG nausea in mornings constipation all day and persistant stomach pain and horrendous belching.Some alteration to diet assisted this and I persevered with it. Now much better less symptoms and much less acid. Heard it can take a month to improve.I'm gonna stick with GP's advise and use it if all else fails but try natural remedies otherwise as it can stop absorbtion of vits and minerals so I'm taking a multivit at same time as don't want lose of magnesium causing ectopic heart rhythmn F 46 10 days

 1  acid reflux cramping, fatigue, insomnia, bloating, gas, and not sure about it but convinced I have some kind of damage to my leg, general body ache I started acid reflux treatment with Ranitidine but started getting brain pains... not unlike an ice cream headache... my doctor put me on nexium for my acid reflux and after a year or so I started to have issues with that too.... I was having difficulty with my lower leg/calf and foot (among other standard issues gas bloating etc)- my leg from knee to ankle lost partial feeling and then I started having cramps. Needless to say I stopped taking it. The cramps went away but I have permanent damage to my leg below the knee and to my toes... less sensation... just feels different from my other leg and has never improved. also have plantar faciitus. I started using over the counter zantac in low dosages... seemed to help the reflux and no brain pain... since it has ranitidine in it I figured maybe it is a dosage thing and long term reaction so I limited when I took the medication to when I was desperate and that helped... but... recently started getting the cramps in my leg again. I also have a general body ache... feels like I am aging (I am 44 but feel like I am a lot older) - my joints seem affected - I think I have always had issues with my joints but I think taking the proton pump inhibitors somehow causes acceleration of body aging... makes worse any bone issues like arthritis etc... cant prove it but I suspect it. the drug works but I am concerned about long term use M 44 3 years

 1  Acid reflux I didn't realize this was causing my affects until I quit taking the Zantac. I've been extremely Nervous, heart palpitations, shortness or breath to the point that I felt extremely lightheaded and even more nervous. I thought I was coming down with something. The bad part about all of this is I felt like I was slipping into a depression, I'm 33 years old and I was getting winded doing my regular workouts. Maybe Maybe a life saver for some but not for me.

 3  Gerd and Gastritis Muscle twitching (crawling/pulsating feeling under my skin) all over my body, heart palpitations (PVCs/PACs), gas and mild sleepiness. This medication worked well for my gerd and gastritis. The side effects took 3-4 months to kick in. It took me several months to taper off this medication and I am no longer on it. Lowering the dose temporarily worsened my gastric symptoms but after a week or two the rebound effects went away. F 29 2 years

 1  As an H2 blocker for Hives anxiety bordering on panic, severe dry mouth and nasal passages, agitation and slight confusion I was prescribed Zantac 150 2X day along with allegra for dealing with chronic hives. I've taken Zantac at lower doses and had not experienced anything like this. Out of the blue I started feeling confused and panicky. Dr. thinks while rare, I may be having an adverse reaction to the Zantac at this dosage. Day two of no meds and feeling a bit better but was prescribed Xanax to use if necessary for the anxiety/panic while I stop taking the Zantac. I woke up today feeling better and thought I was in the clear but by noon, I needed a half dose of the Xanax. Fingers crossed for tomorrow. They are also checking my thyroid so there is a chance it's not the zantac 150. F 45 7 days

 1  stomach acid I became dependent on the drug. See below. I also may have had trouble absorbing calcium and b vitamins. Ranitidine and other H2 blockers, as well as proton pump inhibitors such as omeprazole, are addictive according to a New York Times article in 2013. After doing some internet research following that article, I learned that the body, in its attempt to create enough acid to digest food, counteracts the acid inhibiting effects of these drugs by creating more acid receptors that create more acid, albeit diluted acid as a drug side effect. When you go off the meds, the acid returns to full strength, but this time around you have more receptors than ever, going full blast. The resulting pain leads people to go back on the meds, thinking they still need it, and the vicious cycle begins. I was on this cycle for 28 years. Now that I understand it, I have been able to go off very slowly, with a tiny bit of pain each time I go down a bit. Once I get used to the new dose I go down further. I'm now feeling better than ever. F 54 28 years

 4  GERD Nightmares I have found that taking a generic (Sainsbury's) ranitidine 75mg around 8pm in the evening gives me relief from heartburn for around 24 hours. If I forget to take it I will wake up around 2am with severe heartburn so I am confident it is doing something. Very low cost, around 1 for 12 tablets. I have seen my doctor who says it is OK to keep teking it, but to go back and see her if anything changes, they may decide to do an internal endoscope examination. But for now I'm happy to carry on with the single daily dose. M 56 60 days

 3  Gastritis None Didn't seem to do much, good or bad. I took it as prescribed and still found that I couldn't eat most "solid" foods without nausea, discomfort, or pain. I'm not sure that this drug helped me, as it's possible I might have just healed on my own. It's possible that it helped, though, and my gastritis did go away. It just took a long time. F 19 20 days

 3  Oesophagitis Fatigue; night sweats; headache Zantac certainly eased my oesophagtis but the side effects were unpleasant (see above). My real cure involved (a) losing some weight; (b) laying off fatty food, coffee, acidic food etc. As is so often the case, treating your own body more kindly is the right way forward.I was just being lazy. Drugs lead to more drugs. The ones you get from the doctor are just the same as the ones that junkies buy from the street corner. I feel bad that I thought there was a quick fix. There isn't. I needed to lose weight and eat better. M 54 14 days

 1  Hoarseness from GERD Diarrhea, gas, bloating, belching, upper left abdominal pain, complete lack of appetite, weight loss, felt just plain SICK This medication made me sicker than I have ever been from a medication. It started off okay for the first few days, then the diarrhea began and got worse and worse. I had no appetite and literally felt like vomiting if food went into my mouth. I was constantly bloated and wound up losing six pounds in three days before I gave up. Worst of all, I began to experience a pain in my upper left abdomen that was like a stabbing knife. The diarrhea-OMG! It was explosive. I couldn't even leave the house. My doctor kept saying it was the stomach flu. Ha! I'd like to see him live through over three weeks of this.

 3  nausea resulting from kidney stones haven't had much problem with dyspepsia for years, but when my kidney stones make my back cramp badly it makes my stomach to upset to keep food down, and passing, and to take pain killers. It actually seems to abate the cramping better than the pain killers, but I am unsure if it address the cause or the result of my digestive discomfort. Kidneys do not feel pain per se, the pain comes from the cramps in the back as a result of the damage. Possibly the zantac is blocking this signal? in any case, it always seemed to bring on reflux before taking it away before, but now it seems integral in management of my back pain from kidney stones. I would be interested to hear if anyone else has similar experiences and ideas about them. to feel totally pain and nausea free has been requiring three 150s a day, I don't like the way this dosage makes my head feel, akin to a slight light-headedness M 48 3 days

 3  Acid reflux Experienced dizziness, dry eyes, tingling sensations in hands, higher anxiety, loss of apetite I had no idea this medication had so many side effects. After 6 days on it, I began to feel very strange and not like myself.I got online tonight to research the medication and after reading all of the reviews, I now know it is because of the Zantac. I have stopped taking it and will look at other options. I couldn't understand why I was so anxious and not like myself. So glad I'm not crazy! F 17 7 days

 2  acid reflux took 3wks to finally kicked in and do its job. Anxiety. Shakiness and weakness of arms and legs. Burning/heat sensation on back. Malaise. Nausea. And recently added to my dilemma, trapped gas which gives dyspepsia like pain, pelvic pain, kidney pain. What made me sure it is trapped gas is I felt relieved after belching and tooting! (sorry) took a while to work its purpose. If people respond to tums, gaviscon, mylanta and such, stay away from this med. I dont intend to stay on this med too long! I hope I can wean myself when acid reflux is totally controlled and will respond to antacid. F 43 5 weeks

Unfortunately there were too many side effects of the drug, it did however reduce my upper abdominal pain. I've also tried omeprazole and i've had worse effects.

 4  Gastritis Headaches for the last 2 days...will continue to see if there is any improvement over the next several days. Have taken every brand of PPI's and H2 drugs on and off over the last 8 years. All of the drugs improved my stomach related issues, but all have caused me heart arrhythmia and other symptoms mentioned on this site. (tachycardia, PVCs, PACs, insomnia, sweats). I have refused to take any of these meds for this reason, but it seems I have no other options at this time of need.. So. I'm taking Zantac again, but have since found that adding a magnesium supplement of 200mg /day (which is less than the RDA) seems to prevent the arrhythmia. (knock on wood) and other symptoms. A holistic doctor told me about the magnesium and acid reducers. Most people do not get adequate magnesium in their diets and the acid reducers deplete the level even more. You need to take specific brands of magnesium for best absorption.

Went off and started taking a good probiotic along with digestive enzymes with my meals. Entirely gave up coffee, tea, fried foods, soda, processed foods and raised the head of my bed 6". Drank natural aloe/papaya juice that heals the throat. Am 90% better in just a week taking the generic Zantac once a day after my lunch meal. Feel SO much better. Tried to drink a bit of milk this evening though and slight burning occurred, so I have a way to go. I will stop the Zantac and continue to treat naturally in about a week.

 2  Acid Reflux / GERD Anxiety, night sweats (maybe caused by the anxiety), dull ache in chest, stomach pain/discomfort, general sense of unease. I have not been clinically diagnosed with acid reflux or GERD, but I sure have the symptoms - pain in mid-chest near breastbone, congestion after eating, constantly clearing my throat. My wife had used Zantac 75 & 150 for some time without any problems, so I thought I would give it a try. Worked for the GERD symptoms, but caused the others as described, which caused more anxiety. I really didn't associate these new symptoms with Zancat since it's OTC, but reading what others have written on this site, there is not doubt in my mind. The only reason I gave it a '2' rather than '1' is that it worked for the GERD, and others mat not have any problems. I won't be taking this again - unless I want to scare the crap out of myself.
