Iomeron (Iomeprol)

• Iomeron is used as an iodinated contrast medium to improve image quality in vascular and cross‑sectional imaging procedures.
• Angiography: enhances visualization of blood vessels, allowing detailed assessment of arterial and venous anatomy.
• Computed Tomography (CT) imaging: increases contrast between tissues, facilitating detection of lesions and organ pathology.
• Cardiac CT: provides clear delineation of coronary arteries and cardiac chambers for functional and anatomical evaluation.

• Iomeprol contains a high concentration of iodine atoms that strongly attenuate X‑ray photons. When administered intra‑arterially, intravenously, or intrathecally, the iodine molecules distribute within the vascular and extracellular spaces, creating a radiopaque environment that appears bright on radiographic, CT, and fluoroscopic images. This property allows clinicians to differentiate vascular structures from adjacent organs during diagnostic procedures.

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

Common Side Effects

• Nausea: transient feeling of sickness often occurring during or shortly after injection.
• Warm sensation: brief flushing or feeling of heat at the injection site.
• Metallic taste: temporary metallic flavor in the mouth.
• Mild headache: short‑lasting headache following administration.

Serious or Rare Side Effects

• Anaphylactic reaction: severe allergic response that can include airway obstruction, hypotension, and shock.
• Acute kidney injury: sudden deterioration of renal function, particularly in patients with pre‑existing kidney disease.
• Cardiac arrhythmia: abnormal heart rhythm that may require monitoring or intervention.

Prior to using Iomeron, clinicians should observe several precautionary measures to minimize risk.

• Assess renal function: evaluate serum creatinine and eGFR before administration.
• Review allergy history: identify prior reactions to iodinated contrast or iodine‑containing substances.
• Ensure adequate hydration: encourage fluid intake or intravenous hydration to protect kidney function.
• Monitor vital signs: observe blood pressure and heart rate during and after injection.
• Discontinue metformin temporarily: hold metformin in patients at risk of contrast‑induced nephropathy.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Iomeron can interact with certain medications, influencing safety or efficacy.

Major Interactions (Avoid)

• Metformin: risk of lactic acidosis in patients with impaired renal function after contrast exposure.
• Thyroid hormone therapy: excess iodine may alter thyroid hormone levels, leading to hyper‑ or hypothyroidism.
• Radioactive iodine therapy: iodine load can interfere with therapeutic efficacy.

Moderate Interactions (Monitor Closely)

• NSAIDs: concurrent use may increase risk of contrast‑induced nephropathy; monitor renal parameters.
• Diuretics: may exacerbate volume depletion and renal impairment; ensure adequate hydration.
