Medicinal charcoal tablets can lower creatinine. Medicinal charcoal tablets are an adsorbent agent that physically adsorbs small molecule toxins, including toxic substances such as creatinine and urea nitrogen, from the patient’s intestines. So that they do not circulate in the body, but are eliminated from the intestines, reducing the amount of creatinine and uric acid accumulated in the patient’s body. Therefore, medicinal charcoal tablets not only reduce a patient’s creatinine, but also serve to lower blood potassium. It is important to note that taking medicated charcoal tablets can also cause patients to experience some side effects, such as bloating and constipation. In this case, patients should stop using medicated charcoal tablets immediately and go to the hospital for treatment. At the same time, medicated charcoal tablets should not be combined with vitamins, antibiotics, digitalis, alkaloids, lactasepsin and other digestive enzymes, so as not to be adsorbed and affect the efficacy. If creatinine continues to increase, patients should go to the hospital as soon as possible for examination to clarify the cause, and under the guidance and advice of specialized doctors, treatment should be carried out according to the cause of the disease.
