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 notify all your child's healthcare providers and lab workers 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 caution, as the risk of side effects may be higher in some pediatric patients. In children under 3 years of age, the use of similar medications 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, 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 in cases of severe overdose or renal failure. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Major Interactions
- Metformin (in patients with acute kidney injury or severe chronic kidney disease)
- Interleukin-2 (risk of delayed adverse reactions)
Moderate Interactions
- Beta-blockers (increased risk of anaphylactoid reactions, blunted response to epinephrine)
- Diuretics (increased risk of dehydration and CIN)
- Nephrotoxic drugs (e.g., NSAIDs, aminoglycosides, cisplatin - increased risk of CIN)
- Oral cholecystographic agents (may interfere with imaging)
Monitoring
Baseline Monitoring
Rationale: To assess risk of contrast-induced nephropathy (CIN) and guide hydration strategies.
Timing: Prior to contrast administration, especially in patients with risk factors for renal impairment.
Rationale: To identify patients at increased risk of hypersensitivity reactions.
Timing: Prior to contrast administration.
Rationale: Iodinated contrast can induce hyperthyroidism in susceptible individuals (e.g., those with latent hyperthyroidism or autonomous thyroid nodules).
Timing: Consider in patients with known thyroid disease or risk factors.
Routine Monitoring
Frequency: During and immediately after injection, then as clinically indicated.
Target: Within patient's normal limits.
Action Threshold: Significant deviations (e.g., hypotension, bradycardia, respiratory distress) require immediate intervention.
Frequency: Continuously during and for a period after injection (e.g., 30-60 minutes).
Target: Absence of symptoms.
Action Threshold: Rash, urticaria, angioedema, bronchospasm, hypotension, or anaphylaxis require immediate treatment.
Frequency: 24-72 hours post-contrast in high-risk patients (e.g., pre-existing CKD, diabetes, dehydration).
Target: Stable or returning to baseline.
Action Threshold: Increase in serum creatinine by ≥ 0.3 mg/dL or ≥ 50% from baseline within 48-72 hours indicates CIN.
Symptom Monitoring
- Rash
- Hives (urticaria)
- Itching (pruritus)
- Swelling of face, lips, tongue, or throat (angioedema)
- Difficulty breathing (dyspnea, bronchospasm)
- Wheezing
- Dizziness
- Lightheadedness
- Nausea
- Vomiting
- Flushing
- Headache
- Chest pain
- Changes in urine output (decreased)
Special Patient Groups
Pregnancy
Category B. Animal studies have not shown fetal harm. Human data are limited, but systemic absorption is minimal. Use only if clearly needed and potential benefits outweigh risks.
Trimester-Specific Risks:
Lactation
L2 (Safer). Minimal excretion into breast milk. Less than 0.01% of the administered dose is excreted into breast milk within 24 hours. Infant exposure is very low. Breastfeeding can generally be continued without interruption.
Pediatric Use
Dosing is weight-based. Safety and efficacy are established. Special attention to hydration and renal function is important, especially in neonates and infants due to immature renal function and higher susceptibility to fluid shifts.
Geriatric Use
No specific dose adjustment based on age alone. However, elderly patients are more likely to have pre-existing renal impairment, diabetes, or cardiovascular disease, increasing the risk of CIN and other adverse reactions. Careful assessment of renal function and hydration status is crucial.
Clinical Information
Clinical Pearls
- Iodixanol is iso-osmolar to blood, which may lead to a lower incidence of pain and warmth upon injection compared to hyperosmolar contrast media.
- Adequate hydration is the most important prophylactic measure against contrast-induced nephropathy (CIN), especially in high-risk patients.
- Patients on metformin should have their renal function assessed. Metformin should be withheld in patients with eGFR <30 mL/min/1.73m² or acute kidney injury, and for 48 hours after contrast administration in patients at risk for CIN, resuming only after renal function is stable.
- Always have resuscitation equipment and trained personnel immediately available for managing potential severe hypersensitivity reactions.
- Consider pre-medication with corticosteroids and antihistamines for patients with a history of previous contrast reactions, though this does not guarantee prevention.
Alternative Therapies
- Iohexol (Omnipaque)
- Iopamidol (Isovue)
- Ioversol (Optiray)
- Ioxaglate (Hexabrix - ionic, low-osmolar)
- Gadolinium-based contrast agents (for MRI, different mechanism, used when iodinated contrast is contraindicated or for specific indications)
