What Iopromide is and how it works

Uses, formulations, monitoring, and supply rules can differ by patient, product, and country. Follow the exact local product information and professional advice.

Mechanism of action: how Iopromide works

Iopromide is a non-ionic, low-osmolar iodinated contrast agent. It increases the radiopacity of blood vessels and tissues by absorbing X-rays due to its iodine content. This allows for enhanced visualization of anatomical structures during radiographic imaging. Iopromide does not undergo significant metabolism and is excreted unchanged in the urine. (1) (2)

Serious warnings

FDA BOXED WARNING (ADDED — absent from the earlier draft of this record) — serious

Symptoms: FDA BOXED WARNING (ADDED — absent from the earlier draft of this record): inadvertent INTRATHECAL (spinal) administration of iopromide may cause death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema. Iopromide is contraindicated for intrathecal use; this is a route-of-administration risk managed by the healthcare team giving the injection.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Risk of allergic or hypersensitivity reactions, including anaphylaxis — serious

Symptoms: Risk of allergic or hypersensitivity reactions, including anaphylaxis. May cause kidney injury, especially in patients with pre-existing kidney disease or diabetes. Use with caution in patients with heart disease or severe dehydration. May interact with certain medications, such as metformin. Inform your doctor of any thyroid disorders — iopromide and other iodinated contrast agents can trigger thyroid storm in patients with hyperthyroidism or an autonomously functioning thyroid nodule.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Contraindications recorded in the clinician database — serious

Symptoms: Contraindications recorded in the clinician database: Contraindications include known hypersensitivity to iopromide or other iodinated contrast agents, severe uncontrolled hyperthyroidism, and intrathecal (spinal) use. Preparatory dehydration is contraindicated in pediatric patients because of the risk of renal failure. Use with caution in patients with renal impairment, diabetes, multiple myeloma, severe cardiac disease, or a history of contrast-induced reactions. Pre-procedure hydration and post-procedure monitoring are recommended in high-risk patients.

Action: Follow the urgency stated and seek prompt or emergency care when indicated. (2)

Interactions

Medicine or testEffectAction
Recorded interactionsIopromide may interact with nephrotoxic drugs (e.g., aminoglycosides, NSAIDs), increasing the risk of kidney injury. CORRECTED — the metformin interaction is more specific than a general caution: the FDA label recommends pausing metformin at, or before, iopromide administration specifically in patients with an eGFR of 30-60 mL/min/1.73m², a history of hepatic impairment, alcoholism, or heart failure, or those receiving intra-arterial iodinated contrast, with renal function re-evaluated about 48 hours later before restarting metformin. This is a decision for the prescribing team, not a self-directed change. Always inform your healthcare provider about all medications and supplements you are taking before receiving iopromide. (1)

Pregnancy, breastfeeding, kidney/liver function, age

Pregnancy

Animal reproduction studies at doses up to 0.35-0.7 times the maximum recommended human dose showed no adverse developmental effects; limited human case reports show iopromide crosses the placenta in small amounts. No specific pregnancy category is assigned by the FDA label — whether to use iopromide during pregnancy is a clinical judgment made with the ordering clinician, weighing the diagnostic benefit against any potential risk. (2)

Breastfeeding

Interrupting breastfeeding is not required after iopromide administration. As an optional precaution, some clinicians may suggest interrupting breastfeeding and pumping and discarding milk for 12-24 hours afterward to further reduce infant exposure — this is a choice to discuss with the clinician managing your or your baby's care, not a requirement. (2)

Children

Frequency: Not applicable.. Weight Based: Not recommended for pediatric use.. Max Daily Dose: Not applicable.. Max Single Dose: Not applicable.. Age Restrictions: Safety not established in children. Preparatory dehydration is contraindicated in pediatric patients because of the risk of renal failure. (2)

Renal_impairment

The FDA label explains that iopromide is cleared mainly by the kidneys, and the risk of side effects may be greater in people with reduced kidney function — the more severe the kidney impairment, the more slowly the contrast is cleared from the body (plasma levels were about 2 times higher with moderate kidney impairment and about 6 times higher with severe kidney impairment, compared with normal kidney function). Because of this, the imaging team uses the lowest dose needed to get a diagnostic result in anyone with reduced kidney function, and checks kidney function before and after the scan in higher-risk patients. Having both reduced kidney function and liver or heart disease together further raises the risk of fluid/circulatory strain from the contrast dye, especially with repeated or larger doses. See also the metformin guidance above. (2)

Hepatic_impairment

The FDA label explains that iopromide is cleared mainly by the kidneys, and the risk of side effects may be greater in people with reduced kidney function — the more severe the kidney impairment, the more slowly the contrast is cleared from the body (plasma levels were about 2 times higher with moderate kidney impairment and about 6 times higher with severe kidney impairment, compared with normal kidney function). Because of this, the imaging team uses the lowest dose needed to get a diagnostic result in anyone with reduced kidney function, and checks kidney function before and after the scan in higher-risk patients.

General

Indication: Computed Tomography (CT) imaging

Dose summary: The standard dose of Iopromide for adults varies based on the type of imaging procedure. For most procedures, a typical dose ranges from 300 to 400 mg iodine per mL. Not for intrathecal (spinal) use — see boxed warning.

Renal context: The FDA label states iopromide is substantially excreted by the kidney and the risk of adverse reactions may be greater with impaired renal function; clearance decreases as the degree of renal impairment increases, producing delayed opacification of the urinary system. In pharmacokinetic studies, total clearance decreased proportionately with baseline creatinine clearance, and plasma AUC increased about 2-fold in moderate renal impairment and about 6-fold in severe renal impairment versus normal renal function; terminal half-life rose from 2.2 hours (normal renal function) to 11.6 hours in severe renal impairment. The label advises using the lowest necessary dose of Ultravist in patients with renal dysfunction; no fixed reduced-dose table is given. Combined renal and hepatic (or renal and cardiac) disease increases the risk of hemodynamic disturbance from the contrast load, particularly with repeat or large doses. See also the metformin/eGFR-specific interaction guidance in the interactions section. (1) (2)

Mechanism of action
