Lipiodol Ultra Fluid (Ethyl Esters Of Iodised Fatty Acids From Poppyseed Oil)

Lipiodol Ultra Fluid, an iodinated oil‑based contrast agent, is employed in radiographic procedures that require detailed visualization of vascular and uterine structures.

• Lymphangiography: provides high‑contrast imaging of lymphatic vessels to assess obstruction or leakage.
• Hysterosalpingography: outlines the uterine cavity and fallopian tubes to evaluate patency in infertility investigations.
• Embolization procedures: serves as a carrier for embolic materials to occlude targeted vessels during interventional radiology.
• Vascular contrast imaging: enhances X‑ray visualization of arterial and venous anatomy during angiography.

• Ethiodized oil contains a high concentration of iodine atoms bound within fatty acid esters, which absorb X‑ray photons and create radiopacity. When injected intra‑arterially or intra‑uterinely, the oil distributes within the vascular or uterine lumen, allowing the iodine to attenuate the X‑ray beam and produce a clear contrast between the filled structures and surrounding tissues. This physical property enables precise delineation of anatomical details during imaging studies.

Adverse reactions to Lipiodol Ultra Fluid are generally related to its iodine content and oil composition.

Common Side Effects

• Injection site pain: mild discomfort at the site of administration.
• Nausea or vomiting: transient gastrointestinal upset following injection.
• Headache: mild to moderate headache occurring shortly after the procedure.
• Skin reactions: rash or pruritus at the injection site.

Serious or Rare Side Effects

• Anaphylactic reaction: severe allergic response requiring immediate medical intervention.
• Pulmonary embolism: rare occurrence of oil emboli causing respiratory compromise.
• Renal impairment: acute kidney injury in susceptible patients due to iodine load.
• Thyroid dysfunction: hyper- or hypothyroidism triggered by excess iodine exposure.

Prior to using Lipiodol Ultra Fluid, clinicians should observe specific safety measures to minimize risks.

• Patient assessment: review history of iodine allergy or hypersensitivity before administration.
• Renal function: evaluate kidney function and monitor creatinine levels in patients with renal impairment.
• Thyroid status: consider baseline thyroid function tests due to potential iodine‑induced thyroid effects.
• Pregnancy considerations: use only when clearly indicated after weighing potential fetal risks.
• Dosage control: ensure administration by trained imaging specialists to avoid extravasation or over‑dosage.
• Store at ambient temperature: keep in original container, protect from light and moisture.

Lipiodol Ultra Fluid may interact with certain medications, influencing iodine load or organ function.

Major Interactions (Avoid)

• Iodine‑containing drugs (e.g., potassium iodide): can increase total iodine exposure and risk of toxicity.
• Thyroid hormone therapy: may exacerbate hyperthyroidism when combined with iodinated contrast.
• Nephrotoxic agents (e.g., aminoglycosides, NSAIDs): heighten risk of renal injury in patients receiving contrast.

Moderate Interactions (Monitor Closely)

• Diuretics: may alter fluid balance during contrast studies, requiring monitoring.
• Anticoagulants: increase bleeding risk if invasive embolization is performed.
• Beta‑blockers: can mask contrast‑induced hypertension, necessitating blood pressure observation.
