Quoted from the “Dosage and Administration” section of the FDA-approved label. Your own dose is the one your doctor prescribes: do not change it on your own.

Preparation of the patient: Appropriate preparation is desirable for optimal results. A laxative the night before the examination and a low residue diet the day before the procedure are recommended.

Read more of this section

Best results are obtained when the bladder is filled with the contrast agent. If desired, the preparation may be diluted with sterile water or sterile saline as indicated in the table below. Administration: After sterile catheterization, the bladder should be filled to capacity with Cystografin using a suitable sterile administration set. Care should be taken to avoid using excessive pressure. The presence of bladder discomfort or reflux and/or spontaneous voiding usually indicates that the bladder is full. Radiography: The commonly employed radiographic techniques should be used. A scout film is recommended before the contrast agent is administered.
