For Helicobacter Pylori Infection "Have completed the 14-day Prevpac treatment. I started the first day expecting horrible side effects. That didn't happen. I had a few nausea moments that lasted only seconds. My bowel movements were totally normal. I will say I became very fatigued, but I slept well and generally felt very good during the entire 14 days. I did have a bit of depression, but I assumed it was caused by the treatment, so I just ignored that. It was 8 pills a day, plus a probiotic. That's 126 pills in two weeks! As you can see, it didn't affect my mathematical skills! Today is the 2nd day pill free and done with Prevpac. I don't remember feeling this good in a long while. The treatment appears to have worked extremely well. So, do I recommend Prevpac - that is a resounding YES. And the best of luck to you all."

For Helicobacter Pylori Infection "I’m on day 9 of this horrible medicine. It’s horrible to me because I got hit with side effects of diarrhea, fatigue, loss of appetite, followed by anxiety and even an episode of depression, which I’m still recovering from. It’s scary to deal with, but I haven’t had heartburn since beginning this and have been able to eat. Before taking the medicine, the infection made me not even want to chew. It is very rough, but I’m almost at the end, and that’s what’s helping me pull through all this. Some tips are to take a probiotic like lactobacillus to help with diarrhea (it’s helped somewhat for me), and avoid any acidic foods, sugars, and salty stuff. I’ve searched through many other reviews of this medicine to make sure I’m not the only one with anxiety and panic attacks. If you take this medicine and go through serious anxiety, please talk to someone about your thoughts, it’ll help. Before this medicine, I’ve never had anxiety or depression. Those side effects are killing me."

For Helicobacter Pylori Infection "So, started off pretty confident. No problems here, what's the big deal? Day 7, projectile vomiting for 24 hours, followed by fatigue, my bits felt on fire, couldn't get out of bed, couldn't work, no appetite, should have gone to the ER for IV fluids. Finished the last dose the night before, nurse said the cure often feels worse than the bug (but the bug can increase the risk of stomach cancer). I hope H. Pylori is gone because I'm really not sure I can do it again. Of course, everyone's experiences are different, wishing you all the best."

For Helicobacter Pylori Infection "Reading these reviews, and at least, good to know I'm not the only one who has struggled with H. Pylori. Saw multiple doctors...all brushed it off. Was finally scheduled for an upper endoscopy. Prior to the appt, felt the worst ever. Symptoms over months had progressed from stomach pain and acid reflux (managed with 40 mg Prilosec twice a day) to fatigue, burping, chest pains, liver and spleen pain, feeling confused and delirious, diarrhea. Finally, a walk-in clinic doctor ordered a stool sample test. I'm on day 3 of Prevpac and feeling better. Metallic taste in the AM but goes away. Loading up on probiotics...highly recommended. Definitely need to take with food. I'll have to retest in about a month, but hoping this works! Best of luck to everyone!!!"

For Helicobacter Pylori Infection "I'm usually very regular, so when I started experiencing stomach discomfort-bloating, constipation, lots of gas-I headed straight to my doctor. I did indeed have H. pylori and was given the Prevpac 14-day treatment. After reading what seemed like pages of negative reviews and side effects, I was hesitant to start the regimen and made a deal with myself that if it didn't work out for me, I'd go toward a more holistic route. I'm on Day 13, and overall I had a positive experience. The first few days I was fatigued, and that eventually went away. I did get a bad taste in my mouth after an hour of taking the medicine. I'm regular again and feel much better. I also took probiotics and cut out sugar, dairy, and gluten, which I think helped as well."

For Helicobacter Pylori Infection "I'm on my fourth day of using the Prevpac for H. pylori infection, which was discovered during a medical procedure (colonoscopy and endoscopy). I was experiencing stomach discomfort (throbbing alternating aches from left to right), which prompted me to have these procedures. Day one: I felt tired and experienced severe stomach pain, including bloating, but it (stomach pain) eventually subsided. Day two: minor stomach pain and little bloating. Day three: I did not experience any pain, but I had the metallic taste and felt fatigued. I have noticed that my bowels are larger (sorry for the extra information) than normal. Details to take into consideration: female and a minority."

For Helicobacter Pylori Infection "For the first week, I was in excruciating pain: nausea, severe abdominal pain, diarrhea, sweating, insomnia, confusion, extreme exhaustion and fatigue, battery acid taste in my mouth, etc. I reached out to my doctor and pharmacist who offered absolutely no help. Through research, I found that taking probiotics/yogurt helps with EVERYTHING, stay as hydrated as you can. I ate a lot of ramen noodles to compensate for actual food/water since my appetite was nonexistent. I didn't think I was going to be able to finish the treatment. If I test positive again, I'm going with natural remedies."

For Helicobacter Pylori Infection "I am so happy I found this site!!! I am on day 10 of the HPAC (amoxicillin/clarithromycin/lansoprazole). The first few days were great. Felt better than I have in the last year. But on day 8, I started to feel ill. Terrible, terrible nausea, stomach ache, headache, loss of energy, can’t sleep, hate food, metallic taste... Thought of stopping treatment, but after reading other posts, I will take some probiotics, yogurt, Gravol, and hope it gets me through the next 4 days. I found if you need quick relief from the stomach pain and nausea for an hour, Gaviscon will help. Hope this works. Could not go through another course of treatment."

For Helicobacter Pylori Infection "I had acute gastritis and went to the ER to get IV fluids. While there, they ran a test for H. pylori and it was positive. My only symptoms prior to the ER visit were frequent heartburn. I was given a prescription for Biaxin, amoxicillin, and omeprazole for 14 days. I got online and was horrified by the reviews. I delayed starting my meds. The first three days were hell on earth: nausea, fatigue, anxiety. I learned very quickly to eat with each dose. I had the metallic taste up until day 10, and then it went away. I'm wrapping up day 12, and while the treatment was tough in the beginning, it is doable. My GI is going to do an EGD in 60 days. I was also told to continue omeprazole for 2 months to heal ulcers and combat rebound reflux. Feeling better!"
