1. Uses of Each Medication

• Rcifax 550 (Rifaximin 550mg) is an antibiotic used to treat certain gut infections such as traveller’s diarrhoea caused by E.coli, hepatic encephalopathy (a brain condition related to liver disease), and irritable bowel syndrome with diarrhoea (IBS-D). It works by targeting bacteria in the intestines to reduce infection and symptoms like abdominal pain and diarrhoea.
• Darolac (Lactobacillus acidophilus) is a probiotic that helps restore and maintain healthy gut bacteria, supporting digestion and overall gut health.
• Dvn Plus (Drotaverine 80mg + Mefenamic Acid 250mg) is used to relieve abdominal pain and reduce inflammation or spasms in the gut.
• Ond (Ondansetron 2mg/5ml) helps prevent nausea and vomiting, often used when these symptoms accompany gastrointestinal issues.

2. Understanding Persistent Stomach Pain
   It’s understandably frustrating to have ongoing stomach pain despite normal blood tests and ultrasound. This can happen because some gastrointestinal conditions, like functional gastrointestinal disorders (e.g., IBS), do not always show up on routine tests. Other causes might include subtle inflammation, motility issues, or sensitivity in the gut.

3. Next Steps and Recommendations

• It is important to follow up with a gastroenterologist who can perform a more detailed evaluation.
• Additional tests such as endoscopy, stool studies, or specialized imaging might be needed to identify the cause.
• Keep a symptom diary noting when pain occurs, its severity, and any triggers. Seek urgent care if you develop severe pain, vomiting, blood in stool, or fever.

4. Medication Use and Management

• Avoid stopping these medications abruptly without consulting your doctor, as symptoms may return or worsen.
• A specialist can tailor treatment based on your specific diagnosis and response to therapy.

5. Supportive Measures

• Consider lifestyle changes such as eating smaller, frequent meals, avoiding spicy or fatty foods, and staying well hydrated.
• Managing stress through relaxation techniques can also help reduce gut symptoms.
