For Helicobacter Pylori Infection "On Pylera for H. pylori, Days 1-3 were okay but days 4-7 were the worst. Loss of appetite, heartburn, acidic reflux, belching (lots of it!), general discomfort, nausea, and vomiting were the worst side effects. Found a way to overcome these: DRINK LOTS OF WATER! Like 2L a day, it'll help out a lot. Recommended food: broth/soup/mashed vegetables, the less solid the better. Try probiotics 15 min before breakfast, so that your intestinal flora stays balanced. Days 8-10 were much better once I drank a lot and ate (semi-)liquid food, I felt almost normal (still acidic reflux in the morning). General discomfort disappeared around day 13. Daily schedule: 9:15 probiotic, 9:30-10:15 breakfast, 12:30-13:15 lunch, 16:30-16:50 snack, 20:00-20:45 dinner. LOTS OF WATER (BUT NO DAIRY) ALL DAY LONG! Don't panic if you're feeling nauseous, stay calm. I tried to meditate and do yoga so that my mind isn't focused on the treatment, it helped psychologically but also physically. Breathe and don't stress yourself!"

For Helicobacter Pylori Infection "Due to H. pylori, I had bloating, indigestion, gas, nausea, some change in bowel movements, stomach pain/cramping/gnawing, acid reflux/heartburn, etc. With Pylera, I had terrible nausea and trouble eating, my whole body was very achy, and I felt totally drained while on Pylera. I took some sick leave and teleworked on worst days. I was regimented about taking the medication on time: 7-7:15 am, 12:15-12:30 pm, 5:15-5:30 pm, 10:15-10:30 pm. That definitely helped. I re-tested 1 month later and no longer have H. pylori. After Pylera, I still had burning/gnawing in my stomach, heartburn, bloating, and trapped gas. Damage done by H. pylori can take at least 2-3 months to heal. I went the natural remedy route: 1) acupuncture, 2) Slippery elm, 3) fresh cabbage juice (this was most helpful). I also decided to temporarily remove coffee, alcohol, spicy food, citrus, tomatoes, chocolate, red meat, and dairy from my diet."

For Helicobacter Pylori Infection "Had a hard time pretty much since the second day. Some people stated you should eat first. Unfortunately, that makes me want to vomit after taking it. No diarrhea (I took probiotics and ate Activia), but weird stools (very dark and frequent). I think my bowels are empty at this point. Appetite is gone. Lost almost 10 pounds. Difficulty sleeping due to nausea and gas pains. Threw up twice. Little energy. Headaches. Feeling stressed and somewhat depressed at times. Crying bouts in the middle of the night. What I described wasn't constant. It came and went throughout the day, but nights were hardest for some reason. Tomorrow is the final day. Can you survive it? Yes. Is it hard? For sure. If H. pylori is gone, then it's worth it. Be strong."

For Helicobacter Pylori Infection "I completed the 10 days of Pylera on September 18. The first few days were not too bad, though like others think, the sheer number of pills each day is inconvenient and overwhelming---especially when you take other meds as well. On or about the 4th day, things changed. I was able to go to work, but the last 6 days were really hard: explosive diarrhea, headaches, bloat, gas, extreme fatigue, irritability, inexplicable crying bouts, and loss of appetite. I felt a bit better the first few days after the medication was finished, but now one week later, I am still experiencing the side effects! I feel worse than when I started the meds. When does it stop? Please share experiences."

For Helicobacter Pylori Infection "I'm back again to tell of my ordeal with Pylera antibiotic. This medication is not a joke. I had all the side effects, the most difficult is loss of appetite and metallic taste in my mouth. I didn't want to even see food or go near it. I was tired and lost weight within 3 days of taking this medication. I had to ignore every social gathering and stay home, cancel all my assignments, and lay in bed helplessly. I thought I would not survive the 10 days. I remember one night I went out in the middle of the night, frustrated and calling the emergency line the doctor gave me. They encouraged me to stay on the course until I finish my last dose yesterday. I feel sorry for everyone who has gone through this, and I wish one day we live without sickness or if there should be an easy way of healing sickness. Please be mentally and physically prepared before taking this medication. I will be doing a breath test in a couple of weeks to see if my sickness is eradicated, speaking from Germany. Thank you."

For Helicobacter Pylori Infection "I wish that I did not take this horrible drug (Pylera). I recently learned that taking raw turmeric would kill the bacteria. During the treatment, I thought I was going to die. I absolutely had no energy. I was dizzy, nauseated, had no appetite. I could not take care of my 3 kids. I could not work. I was in bed and counted down the days to finish the treatment. I was not able to finish the last dosage. Six weeks later, I went in for a breath test and, sure enough, the bacteria was eradicated, but I am left with horrible symptoms. I believe this drug has caused my body to be so weak that my chronic pain has aggravated, and my sensitive stomach has gotten worse. My stomach demands foods every 2-3 hours. I have gained so much weight."

For Helicobacter Pylori Infection "Today is my 10th and final day of taking Pylera (thank goodness). It is very powerful stuff and starts killing bacteria immediately! Unfortunately, the good ones too. The first 3 days or so, I had a lot of diarrhea, dizziness, numbness in my extremities, fatigue, and NO appetite. I was only able to eat fruit smoothies, dairy-free yogurt, and broth soups. As a result, I lost almost 15 lb of weight, and not the good kind. I had to call out of work due to my symptoms and lack of energy. Just be cautious if you take this antibiotic and get lots of rest."

For Helicobacter Pylori Infection "I am on day 6 of the treatment, and I have never felt so awful in my entire life. I am very nauseous all the time, my mouth is dry, I have no appetite, but I force myself to eat to combat this feeling. Urine is a very dark amber color, warm sensation in my knees (like standing in front of a heater), tired all the time, could barely get out of bed after sleeping over 10 hours. I am ready to quit. I feel like H. pylori is better than having to deal with the side effects. I am dizzy, can't focus, and when I walk, I feel very wobbly - it was very hard to drive to work, but I have no other option."

For Helicobacter Pylori Infection "H. pylori. (13.00) Pylera 4x3 + omeprazole 2x1 for 10 days. All doses were taken at the same time 6-7 am/12 pm/6 pm/12 am. Days 1-3 were insane. The nausea - exorcism-like!! I cut all the dairy, multivitamins, products high in calcium and iron. No alcohol. No cigarettes or vaping, which as a smoker I had no cravings at all. Pills after meals and with a little bit of food, it helped to ease the nausea slightly. Was afraid it could affect the treatment. I made sure I was not laying down for 10 mins post-pills. Currently day 9, most symptoms became better after day 5. However, then I felt very exhausted mentally and physically and nearly cried every time taking pills, even when symptoms were not as bad as at the beginning. Over the 9 days, I had many changing side effects: nausea, muscle contractions, dark stools, back and chest rash, sweating, lightheadedness, fever, loss of appetite, sadness, sensitivity to noises and light, fatigue, sour taste, and bloating that never went away :/"

For Helicobacter Pylori Infection "I'm just finishing my 10-day protocol, and I am hoping that I never, ever have to take this poison again. Yes... I felt like I was being poisoned with some toxic combo pill pack. It was horrible. I just knew the 'ends justified the means,' so I pushed through. The side effects I experienced were extreme fatigue, headaches/migraines, dark stools, phlegm, blurry vision, body aches, heart palpitations with cough (which I had to go to the ER for because I almost passed out), neck pain, weird taste in mouth, loss of appetite, nausea, and stomach cramping. It's a good thing I don't work, or else I probably would've been fired. I was literally in bed almost the entire time. So, no... uh-uh... not taking this stuff again."

For Helicobacter Pylori Infection "I am on day 5 and all I can say is I hope this Pylera helps. I've been getting a bad taste in my mouth, insomnia, which makes it so hard to function. Also headaches, stomach pain, extreme fatigue, mood swings, dark stools and urine, loss of appetite, etc. But I am hopeful that this works versus all the other antibiotics I've taken. It seems like a never-ending battle, just about a year now, and getting aggravated with this and being so limited on what to and not to eat to upset me. Hoping for the best. Good luck to all."

I am praying that these symptoms will stop today. My doctor told me to tough it out. There must be a better treatment for H. pylori."

For Helicobacter Pylori Infection "So I finally took my last dose, it was this morning at 1 am. I still feel very tired and nauseous, loss of appetite, but it could also be because I developed oral thrush and had to take fluconazole, so probably all the meds together are not helping the stomach situation. My hardest days were 8-10 because I just could not wait for it to be over. I would say my main issue was I felt weak and tired. I work from home and had to take a day off around my 7th day. I don’t know how they expect people to go in to work, I wouldn’t have been able to. But luckily, I had no vomiting, and I powered through it. Now I’ll update in 1 month if H. pylori is gone!"

For Helicobacter Pylori Infection "I just finished 10 days. It was really hard. Tested positive for H. pylori after endoscopy, as well as gastritis. No ulcers. Pylera really wrecked my stomach. Side effects for me: metallic taste, nausea, dizziness, acid reflux, lack of appetite, excessive burping, sour stomach, gnawing gut, dark green stools. Recommend asking the doctor for anti-nausea meds, which helped a bit. Did not eat dairy, took probiotics every day. Force-feed yourself plain meals to help with meds. Also took omeprazole twice a day. Hope it gets better - so far, I feel awful!"

For Helicobacter Pylori Infection "I was expecting the worst when I read the reviews here. I even threw away my original prescription due to the reviews here. But symptoms (fatigue for the last 4-5 years, lack of appetite, and occasional nausea) were getting too severe to ignore, so I had to bite the bullet and just go for it. As it turns out, this experience wasn’t nearly as bad as the reviews here. On a scale of 1-10, with 10 being the highest level of discomfort, I’d give this drug a 4. I had some diarrhea, weakness, and moments of nausea. But I never came close to throwing up. I’m not going to say it was easy, but it wasn’t all that bad either. It wasn't anything remotely close to the nightmare scenarios I saw written here. Maybe I’m just lucky?"

At night, I get a strong sense of nausea and loss of appetite. It's only day 2, good thing I have a doctor appointment in 2 days because an antiemetic is very much needed. Let's hope the next 8 days don't get any worse than what they are."

For Helicobacter Pylori Infection "40 years young female. I consider myself an average, slightly overweight but generally healthy woman who exercises 3 days a week. Before starting with Pylera and Creon, I read all these reviews about H. pylori bacteria. On meds now, 8th day. Side effects terrible day 1-2, vomiting, uncomfortable, uneasy. Felt everything was dirty, cleaned entire house and laundry. Day 2-4: loss of appetite, extreme bloat, sleepless nights. Terribly tired, everything smells. Mood swings, heart palpitations, stools, dark urine, upset/pain stomach/intestine, bloated, headache, dizziness, weakness. I always had healthy meals: jello and yogurt. I still feel somehow weak, but nothing compared to 1-5. Still can't sleep, and the copper taste is worse, but I have intestinal pain."

The worst side effects showed on days 5 to 10. Sometimes, the dizziness and shortness of breath were so strong that I felt I was dying. But every person has a different reaction.

For Helicobacter Pylori Infection "I had food poisoning in July 2021, recovered in a week but had persistent diarrhea for some reason (frequent bowel movements, not watery stool). My doc checked for H. pylori and it came back positive. I didn’t have any symptoms, but he said it’s better to treat it. Took Pylera, and I have to say it is a very tough medicine. The first two days were the worst: headache, nausea, neck stiffness, loss of appetite, fatigue, dry mouth, mood swings, feeling like I would die and depressed, the worst feeling ever. Then my body started adapting, and symptoms started to come and go throughout the treatment. Black stool, dark urine, and frequent urination. I just finished it 2 days ago and will check if I still have the bacteria or not. Advice: take with food, avoid dairy and alcohol during treatment, water, and good luck."
