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 "I've completed my 7-day Prevpac treatment. I did have side effects after the first day of starting the course of medicines. I experienced a racing heartbeat, slight breathlessness, and diarrhea, only for a few hours, though. But I was absolutely unable to sleep the first night of taking the pills because of the bitter taste in my mouth when I lay down. The bitterness was the one thing that bothered me all the 7 days. Thank goodness that the course is over now. However, the major symptom that I had was severe bloating (firm near the upper abdomen), and it is still there with no visible changes. My GP says it will take time to see results, say at least 2 months. Waiting for the 2 months to fly ASAP, fingers crossed!"

For Helicobacter Pylori Infection "I had bad reflux, night nausea, and heartburn for nearly 7 months before being diagnosed with an endoscopy. Only on Day 3 of therapy (Amoxicillin, Clarithromycin, and Omeprazole). Side effects: mild nausea, no strange taste, but I do get thirsty and I have had quite bad stomach pain (bloating, gas, etc.) and back pain. I was also very scared to take these meds after reading all the comments, but so far so good. The most annoying thing is having to take so many meds at one time! Hoping I have no new side effects. I do take a probiotic and anti-nausea pills twice per day with the antibiotics, and I do take the antibiotics with food. I really hope that after the 14 days I am cured, as I don't want to have to do this again!"

For Helicobacter Pylori Infection "I'm on my 1st day of treatment, and I have gas and my stomach is bloated. I also have a bad headache, and I feel nauseous. In my stomach, I feel movements and little pain. I'm hoping this treatment works."

For Helicobacter Pylori Infection "Day 1.5 because I started the pack last night, no longer wanting to deal with the gas, bloating, stomach pain, weight gain, etc. Had it for years, I'm sure. Today I had blurred vision for about 20 minutes and then a lingering headache all day. Here's hoping it works!"

For Helicobacter Pylori Infection "Day 7 of this Prevpac, feel a little weak. My main side effects are abdominal pain and bloating after taking the doses. Hopefully, it will go away after day 14. We all need to be strong and finish this treatment, it's the only way to get rid of this bacteria."

For Helicobacter Pylori Infection "This is horrible! Don't know if I can continue. Day 3 and have been to the emergency room already. The stomach pain is a lot, nauseous, vomiting, bloated, and just tired. The gastroenterologist warned me. I would get worse before I was better. I just didn't think it would be this bad! I can barely eat, and whatever I can is like a cup of food. Hoping it gets better!"
