Iopamidol
About Iopamidol
Iopamidol is a sterile injection used as a contrast agent to help doctors see clear pictures of the inside of your body during imaging tests. It is commonly used for CT scans, X-rays of blood vessels, and other diagnostic procedures. This medicine does not treat a disease itself, but it helps identify medical conditions accurately.
Unlike daily medicines, you will only receive Iopamidol as a single dose right before your imaging procedure. You do not need to take it regularly, as a healthcare professional will inject it only when needed. It is highly recommended to drink plenty of water before and after your procedure to help your body flush the medicine out safely.
Most people experience only mild, temporary effects like a sudden warm feeling or a metallic taste in the mouth. However, you should alert your healthcare team immediately if you experience hives, itching, breathing difficulties, or severe dizziness during or after the injection.
Do not take this if you have had a severe allergic reaction to contrast dyes or iodine in the past. Before your scan, tell your doctor if you have kidney disease, thyroid problems, diabetes, asthma, or a history of allergies.
Certain medications, like some diabetes drugs, can interact with Iopamidol and affect your kidneys, so your doctor may ask you to temporarily stop taking them. If you are pregnant, breastfeeding, or an older adult, discuss the risks and benefits with your doctor before your scheduled scan.
Uses of Iopamidol
Medicinal Benefits
When used as directed as part of your treatment plan, this medicine may provide the following benefits:

Side Effects of Iopamidol
Common Side Effects (Usually mild):
- A sudden feeling of warmth or flushing
- A metallic taste in your mouth
- Mild nausea or vomiting
- Lightheadedness or mild headache
Serious Side Effects (Consult your doctor right away):
- Signs of a severe allergic reaction, such as swelling of the face, lips, tongue, or throat, and hives
- Difficulty breathing, wheezing, or tightness in the chest
- A sudden drop in urination or unusually dark urine (signs of kidney problems)
- Severe dizziness, confusion, or blue-colored skin and lips
Drug Warnings
- Inspect the liquid: Before the injection, ensure the healthcare professional verifies that the solution is clear, colourless to pale yellow, and free of any visible particles.
- Tell your doctor about kidney disease: If you have pre-existing kidney issues, your doctor may need to perform a blood test to check your kidney function before injecting Iopamidol.
- Disclose your diabetes medications: If you take metformin, tell your doctor. You may need to stop taking it temporarily before or after the injection to protect your kidneys.
- Monitor your injection site: Watch for any swelling, pain, redness, or leaking of fluid at the injection site, and report it to the clinical staff immediately.
- Stay for observation: Plan to remain at the imaging centre for at least 30 minutes after your injection, as most rare but serious allergic reactions happen shortly after administration.
Drug Interactions
- Metformin: Taking this diabetes medicine with Iopamidol may increase the risk of a serious blood condition called lactic acidosis if your kidneys slow down. Your doctor may ask you to stop metformin temporarily before or after the scan.
- Beta-blockers: These blood pressure medicines can increase the risk of experiencing a severe allergic reaction to the injection, and they can make the allergic reaction harder to treat.
- Interleukin-2: If you have received this cancer immunotherapy, you may have a higher risk of delayed skin reactions or flu-like symptoms after receiving Iopamidol.

Disease/Condition Glossary
Angiography: Angiography is a medical procedure that is used to visualise blood vessels in the body. It is primarily used to diagnose and evaluate conditions such as blockages or narrowing in the blood vessels. It is used for angiography procedures throughout the cardiovascular procedures including Cerebral and Peripheral Arteriography, Coronary Arteriography and Ventriculography, Pediatric Angiocardiography, Selective Visceral Arteriography and Aortography, Peripheral Venography (Phlebography), and Adult and Pediatric Intravenous Excretory Urography and Intravenous Adult and Pediatric Contrast Enhancement of Computed Tomographic (CECT) Head and Body Imaging.
FAQs
Iopamidol (iopamidol) is an iodinated contrast medium used to enhance images during certain X-ray and CT examinations, including angiography. It helps healthcare professionals visualize blood vessels and internal structures and identify abnormalities or other medical conditions.
Iopamidol contains Iopamidol, which opacifies the vessels in the path of flow of the contrast medium, thereby visualising the internal structures of the human body.
No, Iopamidol is not recommended for intrathecal route of administration. It may result in serious adverse effects such as convulsions, cerebral haemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, brain oedema, and death.
Iopamidol (iopamidol) is eliminated mainly through the kidneys and urine. In people with normal kidney function, most of the administered dose is eliminated within about 24 hours. People with impaired kidney function may take longer to clear it. Follow your healthcare provider's advice about fluid intake after the scan.
Yes. Only a very small amount of Iopamidol (iopamidol) passes into breast milk, and very little is absorbed by a breastfeeding baby. Breastfeeding can generally be continued normally after receiving iodinated contrast. If you have specific concerns, discuss them with your doctor.
A brief feeling of warmth or flushing is a very common reaction to the injection of contrast dye. It happens because the blood vessels widen temporarily as the fluid enters your bloodstream. This feeling usually goes away within a minute or two. Talk to your doctor if you feel uncomfortable.
You may be asked to avoid eating solid foods for a few hours before your imaging test to prevent nausea or stomach upset. However, you should continue to drink plain water to stay well-hydrated. Talk to your doctor or the imaging clinic for specific instructions.
In some cases, particularly in patients who already have kidney disease or diabetes, contrast dyes can temporarily affect kidney function. This is why doctors check your kidney health before the scan and advise drinking plenty of water. Talk to your doctor about your kidney health before your procedure.
Having an allergy to iodine itself is not considered a contraindication to receiving Iopamidol. However, tell your healthcare team if you have ever had an allergic or other serious reaction to iodinated contrast media. Your doctor can assess your risk and determine whether any precautions or an alternative imaging approach are needed.
Most people can drive home safely after their procedure once the observation period is over. However, if you feel dizzy, lightheaded, or unwell after the scan, you should arrange for someone else to drive you home. Talk to your doctor or clinic staff if you feel unfit to drive.
Iopamidol is a non-ionic contrast medium, which generally causes fewer side effects and allergic reactions compared to older, ionic contrast agents. Your radiologist will choose the best contrast agent based on your specific health history and the type of scan you need. Talk to your doctor or pharmacist if you want to learn more.
