Seeing blood in your stool is a symptom that requires immediate medical evaluation, not self-medication. There is no single "tablet" to treat this, as the underlying cause must first be diagnosed. It could range from relatively benign conditions like haemorrhoids or anal fissures to more serious issues like inflammatory bowel disease, ulcers, or colorectal polyps. Please do not take any over-the-counter medications without a professional diagnosis. I strongly advise you to consult a healthcare provider or a gastroenterologist promptly for an examination. If you also experience dizziness, weakness, shortness of breath, or are passing large amounts of blood, please go to the nearest emergency room immediately.
