Blood in your stool is a serious symptom that requires immediate medical evaluation. While Normetrogyl plus is prescribed for bacterial and parasitic diarrhoea, the presence of blood means you should not self-medicate or simply switch drugs. You must see a doctor immediately. Hospital admission may be necessary if you have warning signs like a high fever, severe abdominal pain, persistent vomiting, or signs of dehydration (extreme thirst, dizziness, or decreased urination). Please visit an emergency clinic or your doctor right away for a proper physical exam, stool tests, and to determine if you need intravenous fluids or a different, targeted treatment.
