What should I do if I have terrible abdominal pain during H. pylori eradication?

Thank you for sharing your case. Gastrointestinal complaints (including abdominal pain) can and are caused by the treatment itself and should disappear after its completion. In case of doubt, I encourage you to consult your doctor again. It is the doctor who decides whether to treat the patient m.in based on the history of the disease and the previous response to treatment. Only a doctor can decide on a possible change in pharmacotherapy. If you are unable to get to your doctor, the GdziePoLek.pl service also allows you to get a teleconsultation with a doctor: https://www.gdziepolek.pl/telekonsultacja The discomfort should decrease if you use Metronidazole tablets with food, such as a meal or snack. Klacid can be taken both with and without food. It is also worth including a probiotic with proven effects. The most scientific evidence regarding the effectiveness of probiotics in the eradication of H. pylori concerns strains of Lactobacillus and Saccharomyces boulardii, e.g.: Heliprox: https://www.gdziepolek.pl/produkty/100866/heliprox-kapsulki/apteki HelicoGastrin: https://www.gdziepolek.pl/produkty/112638/helicogastrin-kapsulki/apteki Enterol 250: https://www.gdziepolek.pl/produkty/27293/enterol-250-kapsulki/apteki Quick relief from abdominal pain will also be brought by antispasmodics, e.g.: No-spa: https://www.gdziepolek.pl/produkty/54554/no-spa-tabletki/apteki The GdziePoLek.pl service also allows you to book the drug at the nearest stationary pharmacy and pick up after presenting the prescription: Amotax: https://www.gdziepolek.pl/produkty/4818/amotaks-tabletki/apteki Klacid: https://www.gdziepolek.pl/produkty/40214/klacid-tabletki-powlekane/apteki Metronidazole: https://www.gdziepolek.pl/produkty/48758/metronidazol-polpharma-tabletki/apteki?pvid=15729#stacjonarne
