"I’m on day 14/14 of this clarithromycin medication for Pylori. The first few days were good. My only complaint was that the pill was bitter. I used a trick to make sure the drug didn’t touch my tongue: fill mouth with a bit of water, set the pill in your water filled mouth, swallow immediately. Even with this, I noticed the bitter taste in my throat after a few days, but it was better. Week 2 I wasn't feeling as good. I had shortness of breath, racing heart, belching, dizziness, brain fog, nausea in the morning, trouble sleeping, muscle pain in my chest and back, & felt weak. I checked in with my doctor & everything was in working order. It was just the meds My advice: DON'T take on an empty stomach. I tried once and threw it up. Float the pill in your mouth & swallow. Stay off google. Talk to your doctor if you’re worried about your symptoms. Anxiety only makes things worse. Take it easy. Your health is important so get the rest you need. Happy healing everyone You’ve got this!"

"I'm on day 7 of my treatment plan which consists of: 1-omeprazole, 1-clarithromycin, and 2-amoxicllin 2x/day, and bismuth sulf 4x/day. I deal with anxiety terribly and was fearful of this treatment plan after dealing with 4 months of a diagnosis with symptoms of GERD. A sense of relief came when I had to be tested and found that h pylori was causing all of this. Don't get me wrong, I hate that it has come to this but I'm relieved that it is something that can be treated without having to undergo long term treatment as I would have with GERD. I weighed my options and decided to overcome anxiety and take the meds to get rid of this thing. I have experienced the metallic taste, loss of sleep, back pains, dark stools, and brain fog. Push through!!! You can do this!!! The thing I've learned is to make sure that you have a well-balanced meal when taking your meds to avoid feeling jittery; eat small meals more times within the day; stay away from foods that will cause acid reflux; and drink lots of water."

"If you're reading this post then odds are you been scouring the internet freaking out and learning about h plyori....and coming across so many negative reviews about the medication. Look guys, you've got a bad infection that basically has 2 layer of protection. You have to attach this bad bug hard and heavy to bust through and kill it. I'm on day 7! And yes the first day I was scared because of the new feelings in my body....weakness, somewhat bad taste in mouth, a little brain fog...but it is NOT THAT BAD! By day 3 I felt like I'm cured! After the first day it gets easier and easier, just take with food and when the side effects show up be calm and cool and relax, if you just relax it's simple. "

"I had been having a persistent heartburn and bloating for a month until my doctor suggested an endoscopy. The result came positive with h pylori. I’m currently taking clarithomycn, amoxicillin with omeprazole for a 10 day course. The first day of taking it my chest pain reduced down but was having panic attacks every now and then. Now on my 3rd day and I’m feeling weak, experiencing shortness of breath and a metallic taste in my mouth. The heartburn and abdominal pain is gone but now just feeling super weak. Can’t wait to finish this medication and be smiling again, stay strong loves we can get out of this."

"Taking this medicine was the worst experience ever, however, I completed my 2 weeks to rid my infection. Now I’m at day 15 since I took my last pill and I’m still dealing with side effects, I’m still having heart palpitations (only one episode a day), increased heart rate and 3 days ago I developed a rash on my face. I’m now able to sleep all night and I’m no longer awaken by my heart pounding out of my chest. I wish I would’ve read these reviews prior to this treatment. I have and appointment next week to find out if it worked. Good luck to all of those that are taking this drug now!"

"I feel so much better having read the posts both good and bad. I had a nasty bout of campylobacter and when the stool sample was analysed up popped h pylori. So 500g clarthyromicin 2 a day, along with 500 of amoxicillin, and 20mg of omezrapole. Within hours of the first tablet I started to feel off. My heart was bouncy all over the place it seems to settle during the day - when I busy so I’m distracted unless it goes completely Tom and Jerry, but night is awful I can’t sleep for all the skipped beats anxiety obviously making the whole thing worse fear of death and a bitter grapefruit taste again worse at night. I’m on a 7 day course and have 5 doses left. And I cannot wait until it’s finished. I’m terrified but thank goodness I’m not alone and that has calmed me more than I can express. Good luck guys it’s just a moment in time, stay strong and dig in xxx PS I’ve given an average rating as I don’t know if I’m cured but I’ve found this deeply horrid"

"I was prescribed Amox-Clarith-Omeprazol for 7 days for my h pylori. Before taking these antibiotics, I read these forums to learn of other people's experiences, and it SCARED ME! So much!!. My understanding is that this combi has 80% effectiveness on h pylori (which I've been suffering from for 10 years undiagnosed). My experience of these drugs: awful metallic taste in the mouth .. that's it!!! I'm on day 2, have had no stomach problems, in fact I think I feel better. My message is: for those who are about to start these medications; PLEASE don't be scared, it's worth it to be cured. Try it, if it's really unbearable, then stop them, but try them, for me they really aren't bad. I'm just hoping I'm part of the 80% and they've worked for me!"

"You're probably on this page because you're anxious and you want to find out if your side effects from clarithromycin are normal or if you'd have to face anything worse. I'm on day 8/10 of this medication day 1 through 3 was really awful like everyone else is saying here I have shivers, bad nausea, excessive salivation, diarrhea and loss of appetite. It stopped from day 4-6 and the nausea and diarrhea started again, the diarrhea is so bad that it hurts when I pass stool now and I don't have an appetite again. I guess we just have to really watch what we eat and hope this goes away soon. Take care, be strong and don't give up. We don't want to be put on a higher dose now do we? Good luck guys"

"About 2 months ago I got a nasty bug so went to the doctors where I was tested for Helico pylori. Then gave me the Prevpac of 500 amox, Clarithromyxin 500 and Omeprazole twice a day. I was told to it all in one go before food. You must eat then 30-45 after for the ppi to work as it starts when your body is digesting. The first 3 days nothing I was great apart from funny taste no appetite and slight runs. The third day I didn’t eat much and by 11 in the night I had a rapid pulse rate and felt unwell. Every day different symptoms. Day 4 I had awful pain in side and tired and didn’t feel well as you will get insomnia. Today my sixth day I woke up with a headache and it’s lasted all day plus I feel dizzy and sick. Insomnia, dizzy, nausea, dysentery pain in side, rapid heart rate once, elevated pulse rate, horrid taste, sweating, memory loss some acid reflux and generally feeling ill. I can’t wait for the last day it is the only thing keeping me going as I do not want to quit."

"I am on 1000mg clarithromycin, 2000mg amoxicillin and 40mg omeprazole a day. I only just started the treatment and I have been feeling a bit sick and have had the bitter/metallic taste. My advice is: do not read reviews. Every time I get sick I look online and terrify myself. I’ve been told not to but I’m a curious person, this time reading these reviews I cried and I never cry. EVERYONE HAS DIFFERENT EXPERIENCES is what I’ve learned. The success rate of this plan is 85% so no matter what you experience it WILL be better than ending up with something much worse like stomach cancer or a stomach ulcer"

"I am currently dealing with gastritis and just found out I am positive for H.Pylori. I was prescribed omeprazole, two 500mg amoxicillin and 500 mg clarithromycin. My 1st dose was yesterday @ noon I got bad nausea that didn't go away even with medication, metallic taste, and severe stomach cramps that did not go away. I ended up at the E.R at 2:30 am During all this I felt racing heart, shaking and I was so anxious! NOTHING was helping! After the exhausting day of physical and emotion symptoms I couldn't sleep at all! I only slept 3.5 hours now round 2 for the medications again! I tried to just take the amoxicillin wait to see if anything then took the clarithromycin and right after that everything is coming back from the day before! I can't handle this medication. I was prescribed it for 2 weeks 2 times a day and I can't with these overpowering side effects! I was completely debilitated all day after the 1st doses! I feel so hopeless right now."

"I'm on 1 Clar(500mg) - 2 amox(500mg)- 1 omeprazole(40mg) for 14 days and 2x per day. Before, I had stomach cramps, acid reflux, chest pains and shortness of breath for 4 mos. So, my GI doctor examined me with UB Test(urea) and it was confirmed I had H. Pylori infection. First 3 days of the treatment was horrible, having a bitter taste, bloating, belching and some slight diarrhea, tinnitus in my ears, sore throat, loss of appetite and the chest pain and shortness of breath is still there. 4th to 11th day side effects are now different as I am having nausea, headaches, bitter taste, palpitations, increased heart rate, stomach cramps, insomnia and hallucinations. Still the chest pain and shortness of breath is still there. I'm on my 12th day taking the meds and side effects are not the same as before but still some sore throat, chest pain and shortness of breath. Hopefully the infection(h.pylori) would go away worried with my kidneys. Hoping for a positive outcome with the triple therapy."

"I am three quarters of a way through a two week course of clarithromycin for h pylori gastritis, along with amoxicillin and an h2 blocker (because I am allergic to PPIs). The first three days were rough as I felt lightheaded and an increase in heart rate. (Resting heart rate between 95-105). I was also very itchy so I used benadryl to mitigate that. But immediately I felt the dizziness go away and the indigestion got better on the third day. On day five, I got the horrible metallic taste in my mouth so I took a teaspoon of manuka honey after the doses. Also take fiber and probiotics and ginger tea. That will help a lot. Overall a really great medicine and I am so happy at getting one step closer to eradicating this horrible h Pylori infection."

"The side effects of this medication were unbearable to the point where I thought I wasn't going to be able to finish the whole 10 day course. It left a disgusting metal taste in my mouth for HOURS. Strong nausea started on day 2 or so, but subsided around day 5. It can be best described almost like morning sickness a pregnant woman would have. On day 7 it actually gave me acid reflux, which was worrying since I thought the medication wasn't working. I stuck with it and made it to the tenth day, words can't describe the happiness I felt throwing the pill bottle away. As horrible as it was, got retested and H. Pylori is officially gone!"

"I am on day 12 of antibiotics for H Pylori , I had a lot of anxiety about taking so many antibiotics, I take 4 Amoxicillin & 2 clarithromycin daily , plus omeprazole twice a day , I thankfully have not had any terrible side effects, only the bad taste in my mouth. I have taken 2 probiotic gummies with each dose plus drank an Activia yogurt with each one . And I’ve drank some kombucha, but not every day . I think replacing some good gut health has helped . I’ve read that blackberries & green tea are good for H pylori also , I tried to educate myself through Google"

"10 day run to get rid of H-pylori. In that 10 days I seem to be one that experienced negative side effects but continued on for the eventual benefit "for me". I experienced extreme fatigue, ringing in ears, forgetfulness, migraine headaches, nasty taste/smell. Had thrush at day 7 and day 10 is here. Feel like I was hit by a truck. Have follow-up to see if H-pylori is gone, will come back to update."

"I was diagnosed with Pylori through a stool test and put on Triple Therapy, I tried this for 4 days, had terrible side effects, insomnia, feeling I was awful, disorientation, high anxiety and feeling terrible. I gave up then I tried again for 3 days then had the same side effects. I then tried again not wanting to give up but on the third night had horrific side effects, insomnia, frequent urination, high anxiety, pains in the stomach and rapid heart beat and thought I was going completely mad. The next day was so bad had to go to hospital ER was checked over was declared okay, but concerned that this medication therapy has done some damage to my kidneys. I guess some people are just sensitive to Triple Therapy as it's very overpowering well done anybody who gets through this treatment and are H Pylori negative."

Biaxin (clarithromycin) "I have terrible anxiety and was very afraid to take biaxin because I'd never taken it before. I worry about crazy things like having an anaphylactic reaction to medications, throat swelling shut, not being able to breathe, hives ect. I was on a triple antibiotic treatment of Biaxin, Flagyl, and Prilosec twice a day with Protonix taken alone every morning. I always ate yogurt twice a day with the medication as well as a meal so I my stomach wouldn't hurt or be upset. I never took the medication without food as instructed so I never had any stomach problems at all. The only side effect I had was an odd taste in my mouth but it wasn't overwhelming or bothersome."

"I have been taking this medicine for 5 days now I am left with 5 more days and I feel like I have to wait for a year to finish this med. I have never in my life experienced this kind of illness due to the medicine I have symptoms like nausea, a metallic test which doesn't go away, abdominal pain in the night only, shortness of breath and also not being able to sleep at night. I hope I will finish it the only thing that is keeping me from stopping this medicine is not wanting to quit as the doctors told me next time the bacteria will not be go away and will get adapted to the medicine. But it is the worst medicine ever I do not ever want to experience this again in my life. I would recommend to take the medicine but you need to take a break from every social life , work that your doing and take the medication at home while resting only."

"Hi Everyone, After years of symptoms, I had an endoscopy and I was diagnosed with H. pylori. My gastroenterologist put me on the treatment called Hp7. A combination of Nexium, amoxicillin, and clarithromycin. I had so many symptoms with this treatment that I contacted my doctor and said that I just can’t do it. At that stage, I was on day 6 of 14 days. The nausea, diarrhea, aches, dizziness, and awful taste in my mouth were unbearable. Anyway, she said that she really wanted me to do the 14 days but if I couldn’t, I had to do at least 7 days and that every day extra was extremely beneficial. So, I just stuck to it. By day 10, the antibiotics gave me terrible oral thrush for which I needed Nilstat drops, which added to the nausea. I am currently on day 14 and feeling proud of myself for sticking to it. I have worked while on the medication as a nurse and have only had to have one day off because of the side effects. Retest in 30 days. Hope it worked."

"I’m 37 and recently diagnosed with H.Pylori. Prescribed treatment plan of Omeprazole, Amox and Clarith. The strange taste in my mouth is AWFUL. When I lick my lips it tastes like pennies/chemicals. Very run down and lethargic with some memory loss and foggy brain. Eyes are dry/burning and feels like an effort to get out of bed and walk to bathroom. Light headache and stiff neck. Runny nose. Lower back pain and gas with burping and hiccups. Strange craving for bananas. Bananas and foods with strong flavor help with taste and bloating. Gum and fruity hard candy helps with taste too. Bowel movements smell strong, fruity and weird in the grossest way. So tired. Need to take naps throughout day."

"I'm on day 4 of a combo of clarithromycin, amoxicilln and omeprazole. I stumbled across this forum and lots of scary side effects. As a few have said I've only had the awful taste in my mouth, nothing else. After 2 days I feel great!! Like my old self . Everyone has different side effects but the people that have bad ones are more likely to comment. Stay positive. These tabs will work."

"Not nearly as bad as I expected. The first day I had a very intense reaction, but found it was just because I was allergic to Omeprazole. When I didn't take it, the only side effects I had were moderate dizziness and an occasional metallic taste. It didn't hinder the taste of food. I am quite sensitive to medications and Clarithromycin hardly bothered me at all. The dizziness even faded after 3 days and I was able to function normally, even exercise. Also, some other advice, as I am a pharmacist. One person mentioned to take this with soda. I advise against that because soft drinks contain phosphoric acid and will likely exacerbate symptoms. Another notable interaction is milk products like ice cream. It helps for a short time, but then the rebound acid makes it worse. Probiotics are not clinically proven to help eradicate the bacteria, but I do recall reading a study that showed they can reduce the gastric inflammation. Good luck, whoever reads this, and I wish you a happy cure."

"Horrible drug, I was prescribe Clarithromycin 500mg twice a day with flagyl 400mg twice a day and rabreprazole ( asiphex) 20mg twice a day every twelve hours. My 1st dosage I started having a raising heart rate I checked my heart rate it was 118bpm per minute. I went to bed and calm down and that start reducing. Every day different side effect this medicine is too strong, I only manage to take it for four days as I couldn’t bare the to tough it out anymore. Feels like my body has left me, lost a few kg in just four days...dizziness, heart palpitations, muscle weakness, feeling like to collapse every seconds is too hard to handle plus feeling like your heart is going to stop. Never again will I try this. God bless peeps"
