When this product is used in combination with theophylline, competitive inhibition of the binding site of cytochrome P450 may lead to a significant reduction in the elimination of theophylline in the liver, a prolonged elimination half-life (t1/2β), an increase in blood concentration, and the occurrence of symptoms of theophylline poisoning, such as nausea, vomiting, tremor, restlessness, agitation, convulsions, palpitations, etc., and should be avoided. If it cannot be avoided, theophylline blood concentration should be measured and the dose adjusted. When cyclosporine is used in combination with this product, its blood concentration increases, and the blood concentration of cyclosporine must be monitored and the dose adjusted. When this product is used in combination with the anticoagulant warfarin, it can enhance the latter's anticoagulant effect. When used in combination, the patient's prothrombin time should be closely monitored and the dose adjusted. Probenecid can reduce the secretion of this product from the renal tubules by about 50%. When used in combination, it may cause toxicity due to the increased blood concentration of this product. This product interferes with the metabolism of caffeine, resulting in reduced caffeine elimination, prolonged blood elimination half-life (t1/2β), and possible central nervous system toxicity.
