Do I have to take antibiotics (prevpac) for h.Pylori if i don't have any ulcers or serious symptoms?

Do I have to take antibiotics (prevpac) for h.Pylori if i don't have any ulcers or serious symptoms?

Yes: H. Pylori can cause serious future symptoms (ulcers, perforation, stomach cancer). Not treating it can adversely affect you in the future, even if you don't have symptoms today. My advice is to discuss your specific concerns with your doctor who prescribed it, and then to take it. ...Read more

Was prescribed Prevpac along with metronidazole for h.pylori, any concerns with this combo? I take Diltiazem, accupril, (quinapril) levothyroxin

Was prescribed Prevpac along with metronidazole for h.pylori, any concerns with this combo? I take Diltiazem, accupril, (quinapril) levothyroxin

Be aware : Prevpac (lansoprazole amoxicillin and clarithromycin) can decrease levothyroxin effectiveness & increase risk for hypothyroidism. Prevpac (lansoprazole amoxicillin and clarithromycin) can increase diltiazem effectiveness which would increase risk for hypotension. Probably mild effect, so no worries but be aware. ...Read more

We can help.: Sorry to hear about your situation. Acid overproduction in the gut can be a source of many GI problems. If you make a virtual appointment I would be happy to discuss this further and possibly get you started on a PrevPac (lansoprazole amoxicillin and clarithromycin). ...Read more

H pylori was neg but doc said take Prevpac since I can't afford EGD yet. Safe to do? Burping/chest pain/regurg/weight loss. PPI 8wks but not working.

Digestive problems: Well a gastroenterologist is an 'expert' in this field - so hopefully something can get worked out for you to have the full evaluation, which helps direct the best treatment. In the meantime, you could try various things for improvement. I'm a big fan of ginger. I recc ginger tea, ginger candies, anything with ginger. Take ginger root, boil for 10 min, add honey -see if that helps. Feel better! ...Read more

After taking prevpack triple therapy for 14days, if no more h pylori  symptoms do I still need to test again? If so how long after  the treatment?

I'm taking prevpack triple therapy for 14 days . Will it eradicate all the h pylori bacteria in one single treatment?

That is the plan: But not always. Occasionally, if you have continued symptoms and are retested and found to have continued h pylori, you may need second course or different antibiotic (choice depending on what doc you speak with). However, the prevpack is suppose to treat it and hopefully end the infection and relieve your symptoms. ...Read more
