Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the allergic reaction and its symptoms.
If you are currently dehydrated, have been experiencing poor nutrition, or have recently used a laxative or diuretic (water pill).
If you have had a skin reaction to this medication or a similar medication in the past.
If you are taking metformin or any other medications that may interact with this drug.
This is not an exhaustive list of potential interactions. Therefore, it is crucial to discuss all of your medications, including prescription and over-the-counter drugs, natural products, and vitamins, with your doctor and pharmacist. This will help ensure that it is safe to take this medication in conjunction with your other medications and health conditions.
Remember, do not start, stop, or adjust the dosage of any medication without first consulting your doctor to confirm that it is safe to do so.
Precautions & Cautions
It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication. Your doctor may need to monitor your blood work regularly, so be sure to discuss this with them.
Although rare, this medication can cause life-threatening or fatal heart problems, including low blood pressure and heart attack. It is crucial to talk to your doctor about these potential risks.
When used in conjunction with certain procedures, this medication can increase the risk of blood clots, which may lead to heart attack and stroke, potentially resulting in death. If you have any questions or concerns, consult your doctor.
This medication may interfere with certain laboratory tests, so it is vital to inform all your child's healthcare providers and laboratory personnel that they are taking this medication.
If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.
Pregnant or breastfeeding women, or those planning to become pregnant, should discuss the benefits and risks of this medication with their doctor.
Special Considerations for Children
When administering this medication to children, use caution, as the risk of side effects may be higher in some pediatric patients. In children under 3 years of age, the use of medications like this one has been associated with low thyroid function, which can impact child development. Your child's doctor may recommend regular thyroid function checks after injection. If you have any questions or concerns, consult your child's doctor.
Overdose Information
Overdose Symptoms:
- Fluid overload (pulmonary edema, heart failure)
- Electrolyte disturbances
- Acute renal failure
- Severe hypersensitivity reactions
What to Do:
Treatment is symptomatic and supportive. Monitor vital signs, fluid and electrolyte balance. Hemodialysis can be used to remove iodixanol from the body if necessary, especially in patients with renal failure. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Major Interactions
- Metformin (in patients with renal impairment or acute kidney injury risk)
- Interleukin-2 (IL-2)
Moderate Interactions
- Beta-blockers
- Diuretics
- Nephrotoxic drugs (e.g., NSAIDs, aminoglycosides, cisplatin)
Monitoring
Baseline Monitoring
Rationale: To assess baseline kidney function and identify patients at risk for contrast-induced acute kidney injury (CI-AKI).
Timing: Within 48 hours prior to administration, especially for patients with risk factors.
Rationale: To identify patients at increased risk for hypersensitivity reactions.
Timing: Prior to administration.
Rationale: Adequate hydration is crucial for preventing CI-AKI.
Timing: Prior to administration.
Rationale: Iodinated contrast can affect thyroid function, especially in patients with pre-existing thyroid disease.
Timing: Consider in patients with known or suspected hyperthyroidism.
Routine Monitoring
Frequency: Before, during, and immediately after injection, then as clinically indicated.
Target: Within patient's normal limits.
Action Threshold: Significant deviations (e.g., hypotension, bradycardia, desaturation) require immediate intervention.
Frequency: Continuously during and for at least 30 minutes post-injection.
Target: Absence of symptoms.
Action Threshold: Urticaria, angioedema, bronchospasm, hypotension, or anaphylaxis require immediate medical attention.
Frequency: 24-72 hours post-administration in high-risk patients (e.g., pre-existing CKD, diabetes, heart failure, concomitant nephrotoxic drugs).
Target: Return to baseline or stable.
Action Threshold: Increase in serum creatinine by ≥0.3 mg/dL or ≥50% from baseline within 48-72 hours indicates CI-AKI.
Symptom Monitoring
- Rash
- Hives (urticaria)
- Itching (pruritus)
- Swelling of face, lips, tongue, or throat (angioedema)
- Difficulty breathing (dyspnea)
- Wheezing
- Cough
- Chest tightness
- Lightheadedness
- Dizziness
- Nausea
- Vomiting
- Flushing
- Headache
- Pain or warmth at injection site
Special Patient Groups
Pregnancy
Use during pregnancy only if clearly needed and the potential benefits outweigh the potential risks to the fetus. Iodixanol crosses the placenta. Category B.
Trimester-Specific Risks:
Lactation
Iodixanol is excreted in human milk in small amounts. The amount absorbed by the infant is minimal. Generally considered compatible with breastfeeding. A temporary interruption of breastfeeding (e.g., for 24 hours) is an option but not typically required.
Pediatric Use
Dosing is weight-based. Safety and efficacy have been established in pediatric patients. Particular attention should be paid to hydration status and renal function, especially in neonates and infants due to immature renal function. Risk of thyroid dysfunction in neonates/infants should be considered, especially in premature infants or those with underlying thyroid conditions.
Geriatric Use
No specific dose adjustment based on age alone. However, elderly patients are more likely to have impaired renal function, cardiovascular disease, and diabetes, which are risk factors for contrast-induced acute kidney injury and other adverse reactions. Careful assessment of renal function and hydration status is crucial.
Clinical Information
Clinical Pearls
- Visipaque is iso-osmolar to blood, which may lead to a lower incidence of discomfort, pain, and heat sensation upon injection compared to hyperosmolar contrast agents.
- Pre-hydration is critical for all patients, especially those at risk for contrast-induced acute kidney injury (CI-AKI).
- Always assess renal function (eGFR) before administering iodinated contrast, particularly in patients with risk factors for CI-AKI.
- Patients on metformin should have their renal function assessed. If eGFR is <30 mL/min/1.73m² or if acute kidney injury is anticipated, metformin should be withheld at the time of or prior to the procedure and for 48 hours afterward, and reinstituted only after renal function is stable.
- Be prepared for hypersensitivity reactions, even in patients with no prior history. Have emergency equipment and medications readily available.
- Consider alternative imaging modalities for patients at very high risk for CI-AKI or severe allergic reactions.
Alternative Therapies
- Other iodinated contrast media (e.g., Iohexol, Iopamidol, Iopromide, Iomeprol, Iodixanol)
- Gadolinium-based contrast agents (for MRI)
- Ultrasound
- Non-contrast CT or MRI
