Conray

INDICATIONS AND USAGE Cysto-Conray II is indicated for use in retrograde cystography and cystourethrography.

DOSAGE AND ADMINISTRATION Patient Preparation Unless contraindicated, an appropriate laxative is given the night before the examination. Radiographic Technique The radiographic procedure normally employed for cystography and cystourethrography should be employed. A preliminary radiograph is recommended before the contrast agent is administered. Administration Sterile catherization is essential. Cysto-Conray II may be introduced by gravity flow using an appropriate venoclysis set or by syringe. Excessive pressure should be avoided with any method of administration. Usual Dosage Cystography and Cystourethrography – Either Conray 43 supplied at 43% w/v or Cysto-Conray II supplied at a 17.2% w/v concentration may be used for these procedures. The desired concentration will vary depending upon the patient’s size and age and also with the technique and equipment used. (SEE CONRAY 43 PACKAGE INSERT FOR SPECIFIC INFORMATION ABOUT THE USE OF THIS PRODUCT.) Sufficient volume of contrast medium is administered to adequately fill the urinary bladder. The volume of solution required will vary depending upon the individual patient. Adults usually require a volume in the range of 200 to 400 mL. Children require a volume in proportion to their body size. The usual dose ranges from 30 to 300 mL.

CONTRAINDICATIONS See WARNINGS concerning inadvertant intrathecal administration.

WARNINGS SEVERE ADVERSE EVENTS – INADVERTENT INTRATHECAL ADMINISTRATION: Serious adverse reactions have been reported due to the inadvertent intrathecal administration of iodinated contrast media that are not indicated for intrathecal use. These serious adverse reactions include: death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema. Special attention must be given to ensure that this drug product is not administered intrathecally.

ADVERSE REACTIONS Irritation of the bladder or ureter, common to some degree to all contrast media administered for retrograde urographic procedures, may occasionally occur. As with all contrast media, intravasation may lead to hypersensitivity reactions such as a sense of warmth, flushing, sneezing, sweating, chills, fever, urticaria, laryngeal edema, bronchospasm, hypertension, hypotension, cardiac arrhythmias and cardiac arrest. Adverse reactions associated with procedural technique include injury to the urethra, bladder, ureter, and introduction of infection. In the event of serious or anaphylactoid reactions, it should be kept in mind that the reactions known to occur with intravenous administration of radiopaque contrast materials are possible.

Use in Pregnancy Category C. Animal reproduction studies have not been conducted with Cysto-Conray II. It is also not known whether this drug can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Cysto-Conray II should be used in pregnant women only if clearly needed.
