Iomeron (Iomeprol)

Iomeron, an iodinated contrast agent, is used to improve visualization of vascular and organ structures in radiographic procedures.

• Angiography: provides enhanced vessel delineation for diagnostic and interventional procedures.
• Computed tomography (CT) imaging: increases tissue contrast to aid detection of lesions and anatomical detail.
• Urography: highlights urinary tract anatomy for accurate assessment.
• Cardiac catheterisation: improves coronary and cardiac chamber imaging during invasive studies.
• Peripheral vascular imaging: clarifies arterial and venous pathways in limb studies.

• Iomeprol contains radiodense iodine atoms that absorb X‑ray photons, thereby increasing attenuation of the X‑ray beam. When injected into the bloodstream, these iodine atoms distribute within vascular and extracellular spaces, creating a temporary contrast between blood‑filled structures and surrounding tissues, which enhances image definition in X‑ray‑based modalities.

Adverse reactions to Iomeron may vary in frequency and severity.

Common Side Effects

• Warmth or flushing sensation during injection.
• Metallic or salty taste in the mouth.
• Nausea or mild vomiting.
• Transient headache.
• Mild urticaria or skin itching.
• Mild hypotension.

Serious or Rare Side Effects

• Anaphylactoid or severe allergic reaction, including bronchospasm and shock.
• Contrast‑induced nephropathy leading to acute kidney injury.
• Thyroid dysfunction from iodine overload, such as hyperthyroidism or hypothyroidism.
• Seizures or neurological disturbances.
• Severe hypotension or cardiovascular collapse.
• Pulmonary edema or acute respiratory distress.

When using Iomeron, clinicians should observe several safety measures.

• Renal function assessment: evaluate baseline kidney function before administration.
• Hydration status: ensure adequate patient hydration to reduce nephrotoxic risk.
• Allergy history: screen for prior reactions to iodinated contrast agents.
• Thyroid disease: consider potential iodine load in patients with thyroid disorders.
• Pregnancy and lactation: use only if clearly needed; benefits must outweigh potential risks.
• Store at ambient temperature: keep below 25°C, protect from light and moisture, retain in original container.

Iomeron may interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Metformin: may precipitate lactic acidosis; discontinue before contrast administration.
• Iodine‑containing drugs (e.g., amiodarone, potassium iodide): increase total iodine load.
• ACE inhibitors or ARBs: can exacerbate contrast‑induced renal impairment.
• Nephrotoxic agents (e.g., aminoglycosides, NSAIDs): heighten risk of kidney injury.

Moderate Interactions (Monitor Closely)

• Diuretics: monitor fluid balance and renal function.
• Beta‑blockers: observe hemodynamic response during cardiac procedures.
• Thyroid hormone therapy: assess thyroid function after contrast exposure.
• Anticoagulants: watch for bleeding if invasive imaging is performed.
• Radiopharmaceuticals: consider cumulative radiation exposure.
