Could Rifaximin and Herbal Supplements Affect H. Pylori Test Results?
Hello everyone, I'm 30 years old and my current medications include 25 mg Tritico and a herbal supplement called Phytobox 4, which includes curcumin, resveratrol, and rutin, in addition to Bitterstofe, a mix of herbal digestion extracts. Today, I underwent a gastroscopy, during which they discovered some ulcers and carried out biopsies alongside a urea breath test. My concern lies in whether the rifaximin treatment I completed two weeks prior—specifically 5 days at a dosage of 400 mg twice daily—might have influenced my H. pylori test results. Additionally, I have been taking Bitterstofe, which comprises extracts from pomegranate, lavender, clove, thyme, and rosemary for about a week leading up to the procedure, along with Phytobox 4, an anti-inflammatory herbal blend that includes curcumin, resveratrol, rutin, and grapeseed extract. How likely is it that these treatments could lead to a false negative in the H. pylori tests? Thank you for your insights!

It's understandable to be concerned about how your recent treatments might affect your H. pylori test results. Rifaximin, as well as herbal supplements, could potentially influence these tests, but let's break this down.
Main Points:
- Rifaximin Treatment: This antibiotic can reduce bacterial loads in the gut, including H. pylori, potentially leading to false-negative test results if taken shortly before testing.
- Herbal Supplements: While less commonly discussed, some herbal ingredients may affect gut health but are less likely to interfere significantly with breath tests.
- Timing is Key: The duration since your last treatment and the timing of your tests are crucial in determining their impact.
Explanation:
-
Rifaximin: This antibiotic specifically targets gut bacteria and can lower the presence of H. pylori, especially if the test is conducted shortly after treatment. Since you finished taking rifaximin two weeks prior, it's plausible that it had some effect, but it would depend on how much time has passed since the last dose.
-
Herbal Supplements: Ingredients like curcumin or thyme have potential antibacterial properties but usually wouldn't affect a breath test as much as antibiotics. However, they could have some influence, particularly if they affect digestion or gut flora.
Next Steps:
-
Monitor Symptoms: Keep track of any ongoing symptoms like abdominal pain, nausea, or changes in digestion. These can inform your doctor about the need for retesting or further assessment.
-
Consult Your Doctor: Share this information with your healthcare provider, especially about the timing of your rifaximin use. They can guide appropriate follow-up tests if necessary.
-
Understand Test Protocols: If further testing is needed, your doctor may recommend waiting a sufficient period after antibiotic use to ensure accurate test results, generally 4-12 weeks after completing antibiotics before retesting for H. pylori.
Please remember that your healthcare provider will be the best resource for your specific situation. If you have any further questions or changes in your condition, don't hesitate to reach out for more personalized advice.

Experiencing Monthly Flu: Is It Common?
At 24 years old, I'm a female resident of the Philippines, and I find myself battling the flu on a monthly basis.

Ongoing Low-Grade Fever Concerns
Greetings, I’m a 23-year-old male, standing at 5'7" and weighing 188 pounds. I take Adderall and do not smoke. For a number of years, I have encountered a troubling issue that is becoming increasingly frustrating. Frequently, both during the day and at night, I experience a low-grade fever ranging from 99°F to 101°F, which can persist for several hours before subsiding. When I mentioned this to my physician, he largely shrugged it off, stating that any temperature below 100.4°F doesn't count as a fever. However, I am quite fed up with feeling chilly and unwell whenever these episodes occur. Could there be alternative explanations for this condition?
High Fever and Body Pain: My Ongoing Struggle
At 24 years old, and standing at 5 feet 8 inches while weighing between 50 to 52 kilograms, I've been enduring a high fever and intense body aches for over five days without any signs of improvement. This prompted my visit to the emergency room. Upon arrival, I underwent a series of tests, including a complete blood count (CBC), CRP, and a chest X-ray in the posterior-anterior view. Fortunately, my CBC and X-ray results came back normal. However, my CRP level was alarmingly high at 43.1 mg. The doctors prescribed me cefixime at a dosage of 400 mg, along with zinc and pantoprazole. When I inquired about pain relief, the medical team assured me that I wouldn't need any, but I've opted to manage my discomfort with paracetamol, taking 650 mg extended-release three times a day. While this has successfully alleviated my fever, I still experience pervasive pain throughout my body. What are the next steps I should consider? Additionally, I was advised to return for the same tests if my condition does not improve within a week.
Concerns About Possible Kidney Infection After UTI Treatment
I’m a 21-year-old female, standing at 5’1" and weighing 190 pounds. At present, I am on a regimen that includes macrobid at a dosage of 100 mg and lexapro at 10 mg, which I have been taking for the past four years. Last Sunday, I received a diagnosis of a urinary tract infection (UTI). My symptoms had begun the previous Thursday, initially leading me to believe that I was just experiencing some discomfort due to a bruised cervix. However, once I started noticing blood in my urine on Sunday, I decided to visit my doctor, who confirmed the UTI. At that point, I was not experiencing any pain in my back. I began treatment with bactrim shortly after the doctor's visit, but due to a mild allergic reaction, I switched to macrobid the following day, which was Monday. Today, I’m feeling quite unwell—experiencing a headache and general body discomfort. After work, I rested for a bit and awoke feeling extremely fatigued, as if I had been run over by a truck. My body aches persist, I’m slightly dizzy, and the headache remains. Additionally, my nose is congested and running, and I’m battling nausea and a diminished appetite. I suspect I might have a low-grade fever as well. I managed to eat dinner, albeit with some effort, and took my third dose of macrobid along with ibuprofen for the headache. While the headache has improved somewhat, I still don’t feel good overall, and I have a mild ache in my lower back. Interestingly, most of my UTI symptoms have subsided—my urine appears normal, and I no longer experience urgency or discomfort. However, I am now left feeling ill. I’m beginning to question whether these sensations are side effects of the antibiotic or if I might be developing a kidney infection instead.
