Are using Pymetphage and have eGFR drops below 45ml/min/1.73m2: It is necessary to re-evaluate the risks - benefits when using the drug to consider whether to continue treatment or not. Patients whose eGFR falls to <30ml/min/1.73m2: The drug should be discontinued. Discontinue Pymetphage while performing an iodinated contrast imaging test.
