Indication	When this product is used simultaneously with antacids containing magnesium or aluminum, sucralfate, metal cations (such as iron), and zinc-containing multivitamin preparations, it will interfere with the absorption of this product by the gastrointestinal tract, causing the concentration of this drug in various systems to be significantly reduced. Therefore, the time of taking the above-mentioned drugs should be at least 2 hours before or after using this product. Avoid using it simultaneously with theophylline. If it is necessary to use it simultaneously, the blood concentration of theophylline should be monitored and the dosage should be adjusted accordingly. When used simultaneously with warfarin or its derivatives, the prothrombin time or other coagulation tests should be monitored. When used simultaneously with non-steroidal anti-inflammatory drugs, there is a possibility of inducing convulsions. When used simultaneously with oral hypoglycemic drugs, it may cause blood sugar disorders, including hyperglycemia and hypoglycemia. Therefore, blood sugar concentrations should be monitored during medication. Once hypoglycemia occurs, this product should be discontinued immediately and appropriate treatment should be given.
