It is normal to have some stomach discomfort when starting treatment for H. pylori, but ongoing severe pain is unusual and should be checked. Sompraz HP has several medicines, including an acid reducer and antibiotics. Mild side effects like nausea, bloating, or loose stools can happen, but if you have severe pain that doesn?t go away, it could mean your body is irritated or not tolerating the medicine well. This isn?t always serious, but because your pain is severe and lasting, it?s important to talk to your doctor. Don?t stop the treatment on your own, since not finishing it can make the bacteria harder to treat. Contact your doctor soon so they can see if your treatment needs to be changed. In the meantime, keep taking your medicines as directed, usually after food if that?s what you were told. Try to eat light, non-spicy meals and drink plenty of water. Stay away from alcohol and foods that might upset your stomach. If your pain gets worse, or if you have vomiting, black stools, or feel weak, get medical help right away. Getting checked quickly will help you finish your treatment safely.
