For Helicobacter Pylori Infection "PEOPLE, PLEASE DON'T COME HERE TO GET FEAR INSTILLED IN YOU ABOUT THIS MEDICINE. Other people's experiences may NOT EVER happen to you. I didn't take it for a whole year because of these kinds of websites. Let's put this out there: I DO NOT LIVE A HEALTHY LIFESTYLE. I eat fried food, I eat out a lot (hence, why I think I got the bacteria). I barely work out, and I'm considered overweight. (NOT BRAGGING, JUST BEING TRUTHFUL) And the medicine still worked for me. If you're dealing with horrific side effects, 9/10 you were probably dealing with those things one way or another without medication. For the nausea, eat 1/2 a toast before taking it. For the insomnia, don't take it right before you go to bed, 2-3 hours in advance. The metallic taste goes away after you eat."

For Helicobacter Pylori Infection "I have had stomach problems for the past 6 years and was prescribed medications such as Nexium, Zantac, and Protonix, however, I saw no results. 2 weeks ago, I went to emergency for extreme stomach pain and vomiting. I was diagnosed with H. pylori and given the 14-day treatment Prevpac. The first couple of days, I had symptoms such as a metal taste in my mouth and feeling fatigued. On day 7, I started getting minor headaches. I am pleased to say I am on day 14 and just finished the pack, and I am feeling great. Make sure to drink lots of fluids and eat healthy during the treatment."

For Helicobacter Pylori Infection "I am a 31-year-old female. I was given Prevpac to get rid of H. pylori, which was the underlying cause of my chronic gastritis and terrible pain and discomfort in my chest from reflux and inflammation. I just completed the 14-day Prevpac kit. This treatment definitely works, and I feel 100% better now that it's over. It takes time for it to fully kick in, though. I started feeling relief at day 5 and felt 100% better at day 10. To me, my experience wasn't as bad as some of the reviews I read prior to starting the medication. Based on suggestions I read, I took a daily probiotic, which helped a lot with the side effects, so I recommend that. The one constant symptom was the metallic taste in my mouth, especially when first waking up. But all I had to do was drink something, and it went away. I had diarrhea a couple of times, but nothing extreme. A few stomach aches/cramps as well. At the very end, I developed a little yeast infection (which can happen when taking antibiotics), but I easily got rid of it with over-the-counter meds. The side effects are very bearable. Overall, the most annoying thing for me was having to take so many pills at once and in one day and also the cost. After my insurance paid their part, I paid $75, which to me is a lot. But the packaging said before insurance it was about $750."

For Helicobacter Pylori Infection "I was positive for H. Pylori. I was nervous to start this 14-day therapy of medicines, but I toughened up and went for it. I am on my second day of Prevpac. I have some symptoms. The first day I took it, about 2 hours after, I felt tired, along with a metallic taste in my mouth. I ate right after I took it and drank plenty of water. The taste went away fairly quickly in the morning, however, in the evening, I got the same symptoms, but the metallic taste was worse. I just kept drinking water. This morning, I woke up with loose stools. Also, for some reason, I have been having an increased appetite. I guess it's a good thing considering I haven't been eating. I am a 27-year-old. I will keep you updated."

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 am on triple therapy for 14 days, second time in 2 years. I'm 5th day in. First 3 were brutal. I couldn't even dress myself, was too weak. My insides feel tender, but I'm not as tired, I can work and sleep. My question is: I have that metallic taste, and now my tongue is light grey. Anyone experience this?"

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 "Don't be afraid to take the Prevpac for H. pylori. I have suffered for a month with pain, nausea, vomiting, and diarrhea. I'm on only day 3 of a 14-day treatment, and I am almost back to my old self again! Many people complain about the side effects, but all I have experienced is a slight metal taste in my mouth at times - so worth being almost well."

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 "Been prescribed this for the second time. (First time Metronidazole, Lansoprazole, and amoxicillin with severe side effects, so I had to stop taking it, including nausea 97% of the time, abdominal cramps, loss of appetite). This is a 7-day treatment. Just finished day 1 of the medication. Took my first dose this morning, had no side effects for 4 hours. I went back to sleep and woke up with a STRONG metallic taste in my mouth that I couldn't flush out. Taken my second dose after dinner and now suffering from upper back pain on my left side. Not sure if it's a side effect from the medication. Also, my guts are moving a lot more as if there's wind trapped inside. These are side effects I can handle for 7 days, hoping I don't get severe nausea."

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!"

For Helicobacter Pylori Infection "I am on day 12. I took the first dose in the evening, and the next morning I woke with the strong metallic taste in my mouth. That taste is there every morning, but I can easily wash it away with a drink of water. Around days 4-6, I had very loose stools from everything I ate. Since then, it has been off and on, but I have at least one loose stool every day. My H. pylori infection caused at least two ulcers, so I was experiencing a lot of nausea before, which has gradually improved with this medication-something must be working. This medication gave me really bad yeast infections (both oral and vaginal), but gargling with hydrogen peroxide a few times cleared it up. And treated the 'other' area. This medication has been tough, but still better than the H. pylori and ulcer symptoms."

For Helicobacter Pylori Infection "Actually, I realized just a week ago that I was having an H. pylori infection, and I started medication yesterday. Meanwhile, I'm doing well, but the side effects are hard. I get a metallic taste, I feel nausea, and when I vomit, I spit just bubbles. It also just makes me feel super tired. But hopefully, I'll get better."
