Iomeron (Iomeprol)

Iomeron is employed in radiographic procedures that require enhanced visualization of vascular and tissue structures.

• Contrast‑enhanced X‑ray imaging: Improves delineation of vessels and organs during standard X‑ray examinations.
• CT angiography: Provides high‑contrast detail of arterial and venous anatomy for accurate diagnosis.
• Digital subtraction angiography: Enhances subtraction images to better display vascular lesions.
• Myelography: Supplies contrast within the spinal canal to outline the subarachnoid space and nerve roots.

• Iomeprol contains multiple iodine atoms with a high atomic number, which markedly increase X‑ray attenuation when the solution circulates in the extracellular fluid. After intravenous, intra‑arterial or intrathecal administration, the iodine‑rich compound distributes rapidly, creating temporary radiodensity that highlights vascular and tissue structures on X‑ray, CT and fluoroscopic imaging, thereby improving diagnostic contrast.

Iomeron may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Warmth or flushing sensation during injection.
• Transient metallic taste in the mouth.
• Nausea or mild vomiting.
• Headache or mild dizziness.

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis) with respiratory compromise.
• Acute kidney injury or worsening of pre‑existing renal impairment.
• Thyroid dysfunction due to iodine load, including hyperthyroidism.
• Hypotension or cardiac arrhythmia.
• Seizures or loss of consciousness.

Prior to administering Iomeron, clinicians should observe several precautionary measures to minimise risk.

• Renal function assessment: Evaluate kidney function and consider hydration status before use.
• Thyroid status: Review patient history for hyperthyroidism or thyroid disorders.
• Allergy history: Screen for prior reactions to iodinated contrast agents.
• Hydration: Ensure adequate fluid intake or intravenous hydration to support renal clearance.
• Pregnancy and lactation: Use only if essential, after risk‑benefit evaluation.
• Store at ambient temperature: Keep in original container, protect from light and moisture.

Iomeron can interact with certain medications, requiring careful assessment before use.

Major Interactions (Avoid)

• Metformin: Risk of lactic acidosis; discontinue before contrast administration.
• Iodinated drugs (e.g., amiodarone): May increase total iodine load and thyroid risk.
• ACE inhibitors: Can exacerbate contrast‑induced renal impairment.

Moderate Interactions (Monitor Closely)

• Diuretics: Monitor fluid balance and renal function closely.
• Nephrotoxic antibiotics (e.g., aminoglycosides): Adjust dosing and observe kidney markers.
• NSAIDs: May affect renal perfusion; consider alternative analgesics.
