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 dehydrated, have a poor diet, or have recently used laxatives or diuretics (water pills) before starting this medication.
If you have experienced a skin reaction to this medication or similar medications in the past.
If you are currently taking metformin or any other medications that may interact with this drug.
This list is not exhaustive, and it is crucial to discuss all your medications, including prescription and over-the-counter drugs, natural products, and vitamins, with your doctor and pharmacist. They will help you determine if it is safe to take this medication with your existing health conditions and medications. Never start, stop, or adjust the dosage of any medication without consulting your doctor first.
Precautions & Cautions
If you are taking this medication, it is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, about your treatment. 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. Additionally, 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 lab 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.
Women who are pregnant, planning to become pregnant, or breastfeeding should discuss the benefits and risks of this medication with their doctor, as it may affect the baby.
Special Considerations for Children
When administering this medication to children, use it with 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 for a period after the injection. If you have any questions or concerns, be sure to discuss them with your child's doctor.
Overdose Information
Overdose Symptoms:
- Fluid overload (e.g., pulmonary edema)
- Electrolyte disturbances
- Acute renal failure
- Cardiovascular collapse
What to Do:
Treatment is symptomatic and supportive. The contrast agent can be removed by hemodialysis. Call 1-800-222-1222 (Poison Control) or seek immediate medical attention.
Drug Interactions
Major Interactions
- Metformin (in patients with renal impairment or acute kidney injury): Increased risk of lactic acidosis. Metformin should be withheld at the time of or prior to the procedure and for 48 hours after, and reinstituted only after renal function is stable.
- Interleukin-2 (IL-2): Increased risk of delayed adverse reactions (e.g., fever, flu-like symptoms, rash, oliguria, renal dysfunction).
Moderate Interactions
- Beta-blockers: Increased risk of anaphylactoid reactions and reduced efficacy of epinephrine in treating such reactions.
- Diuretics: May increase the risk of contrast-induced nephropathy due to dehydration.
- Nephrotoxic drugs (e.g., NSAIDs, aminoglycosides, cisplatin): Concomitant use may increase the risk of contrast-induced nephropathy.
- Oral cholecystographic agents: May interfere with visualization due to residual contrast.
Monitoring
Baseline Monitoring
Rationale: To assess baseline kidney function and risk of contrast-induced nephropathy (CIN).
Timing: Prior to contrast administration, especially in patients with risk factors for CIN.
Rationale: To identify patients at increased risk for hypersensitivity reactions to iodinated contrast media.
Timing: Prior to contrast administration.
Rationale: To assess baseline thyroid status, especially in patients with pre-existing thyroid disease or those at risk for iodine-induced hyperthyroidism.
Timing: Prior to contrast administration, if clinically indicated.
Rationale: Adequate hydration is crucial to minimize the risk of CIN.
Timing: Prior to contrast administration.
Routine Monitoring
Frequency: During and immediately after administration, then as clinically indicated.
Target: Within patient's normal limits.
Action Threshold: Significant deviations, signs of allergic reaction or hemodynamic instability.
Frequency: Continuously during and for a period after administration (e.g., 30-60 minutes).
Target: Absence of symptoms.
Action Threshold: Rash, urticaria, dyspnea, bronchospasm, angioedema, hypotension.
Frequency: 48-72 hours post-contrast in high-risk patients (e.g., pre-existing renal impairment, diabetes, heart failure).
Target: Stable or return to baseline.
Action Threshold: Increase in serum creatinine by âĨ 0.3 mg/dL or âĨ 50% from baseline within 48-72 hours.
Symptom Monitoring
- Rash
- Urticaria (hives)
- Pruritus (itching)
- Dyspnea (shortness of breath)
- Bronchospasm (wheezing)
- Angioedema (swelling of face, lips, tongue)
- Hypotension
- Nausea
- Vomiting
- Headache
- Dizziness
- Flushing
- Metallic taste
- Pain or warmth at injection site
- Signs of extravasation (swelling, pain, redness at injection site)
Special Patient Groups
Pregnancy
Use during pregnancy only if clearly needed and the potential benefit outweighs the potential risk to the fetus. Iodinated contrast agents cross the placenta. Fetal thyroid function should be monitored if exposure occurs.
Trimester-Specific Risks:
Lactation
Minimal amounts of iodixanol are excreted into breast milk. It is generally considered safe for breastfeeding. A decision should be made whether to discontinue breastfeeding for a short period (e.g., 24 hours) or to continue, taking into account the importance of the drug to the mother and the potential risk to the infant.
Pediatric Use
Dosing is weight-based. Pediatric patients, especially neonates and infants, may be more susceptible to fluid shifts, electrolyte imbalances, and thyroid dysfunction. Careful monitoring of hydration and renal function is essential. Risk of contrast-induced nephropathy is generally lower than in adults but still a concern in vulnerable populations.
Geriatric Use
Increased risk of contrast-induced nephropathy due to age-related decline in renal function, comorbidities (e.g., diabetes, heart failure), and polypharmacy. Careful assessment of renal function and hydration status is crucial. Use the lowest effective dose and ensure adequate pre- and post-hydration.
Clinical Information
Clinical Pearls
- Visipaque is iso-osmolar to blood, which may lead to a lower incidence of discomfort (e.g., warmth, pain) and potentially a lower risk of contrast-induced nephropathy compared to hyperosmolar contrast agents, especially in high-risk patients.
- Always ensure adequate hydration before and after contrast administration, particularly in patients with pre-existing renal impairment, diabetes, or heart failure.
- Carefully screen patients for allergies to iodine or previous contrast reactions. Pre-medication with corticosteroids and antihistamines may be considered for patients with a history of moderate to severe reactions.
- Metformin should be withheld in patients with renal dysfunction or acute kidney injury at the time of or prior to the procedure and for 48 hours after, and reinstituted only after renal function is stable.
- Monitor for delayed hypersensitivity reactions, which can occur hours to days after administration.
- Extravasation can occur; monitor injection site and manage according to institutional protocol.
Alternative Therapies
- Other iodinated contrast agents (e.g., Iohexol, Iopamidol, Iopromide, Iodixanol (other concentrations))
- Gadolinium-based contrast agents (for MRI)
- Ultrasound with contrast
- Non-contrast imaging modalities (e.g., non-contrast CT, MRI, ultrasound)
