Iopamidol
Uses of Iopamidol
The primary use of Iopamidol is to enhance visualisation during radiographic procedures such as X-rays, CT scans, and angiographies. It belongs to the group of iodinated contrast agents.
Iopamidol is also employed to improve the contrast in urography for a detailed examination of the urinary tract, and in myelography to assess conditions affecting the spinal cord.
Side effects of Iopamidol
Headache
Nausea and vomiting
Feeling of warmth or flushing
Mild discomfort at the injection site
Dizziness
How Iopamidol works
Iopamidol is an iodinated contrast agent.
It works by enhancing the contrast between the target area and surrounding tissues during imaging procedures. As an iodine-containing medium, it absorbs X-rays more strongly than bodily fluids and soft tissues.
This differential absorption of X-rays helps to create clearer visuals of the internal structures, aiding in accurate diagnosis.
On being administered, Iopamidol quickly distributes in the extracellular fluid space and does not cross intact blood-brain barriers. It is mainly excreted unchanged via the kidneys through glomerular filtration.

Expert Advice
Dosage Forms Available
- Iopamidol is available in the form of a sterile aqueous solution for intravenous, intraarterial, or intrathecal administration. It is also used orally for certain diagnostic procedures.
Age and Dose Restrictions
- This medicine is intended for use in both adults and children. The specific age range and dosage are determined by the type of diagnostic procedure and the patient's individual circumstances.
Contraindications
- Iopamidol is contraindicated for patients with known hypersensitivity to it or any other components in its formulation.
Other Medications to Avoid
- Iopamidol may interact with beta-blockers (such as propranolol and metoprolol), antihypertensive medicines (like lisinopril and amlodipine), metformin, interleukin-2, nephrotoxic medicines (like aminoglycosides) and medicines that lower seizure threshold (such as bupropion and tramadol).
Overdose and Missed Dose
- An overdose of Iopamidol may lead to symptoms like nausea, vomiting, dizziness, hypotension (low blood pressure), seizures, and in severe cases, renal failure or cardiovascular complications. In this case, immediate medical attention is required.
- Due to its diagnostic use, there is usually no issue of a missed dose. However, if a diagnostic procedure has to be rescheduled, the physician will determine the best course of action based on the individual patient's situation.
Management of Side Effects
Most side effects are temporary and usually resolve when discontinuing this medicine. However, if you experience any severe side effects or worsening of the symptoms, please consult your doctor.
- Resting in a comfortable position may help manage dizziness or headache after the procedure.
Use in Driving and Operating Machinery
- As Iopamidol can cause dizziness or fainting, it is advised to avoid driving or operating heavy machinery for at least 24 hours after the administration of this medicine.
Use in Pregnancy and Lactation
- It is generally recommended to avoid using Iopamidol during pregnancy and breastfeeding unless absolutely necessary. Always consult your doctor before use.
Caution in Other Conditions
- Caution should be exercised in patients with kidney disease, heart problems, thyroid disorders, diabetes, and asthma. It is recommended to discuss your medical history with your doctor before undergoing any procedure involving Iopamidol.
Special Dietary and Lifestyle Recommendations
- Drinking plenty of fluids before and after a diagnostic procedure can enhance the elimination of the contrast agent from the body.
- If you have any pre-existing conditions such as diabetes or hypertension, ensure that they are well-managed. This can decrease the risk of adverse effects related to the use of contrast agents.
Frequently asked questions
Is Iopamidol a steroid?
No, Iopamidol is not a steroid. It belongs to a class of medicines known as iodinated contrast agents that are used to enhance the visibility of internal body structures during certain imaging procedures.
Does Iopamidol have any effect on sleep?

Is it safe to take Iopamidol daily?
Iopamidol is typically used on an as-needed basis for diagnostic imaging procedures and is not intended for daily use. Always follow your doctor's instructions regarding its administration.
How much time does Iopamidol take to work?
The effects of Iopamidol are usually immediate after administration, as it enhances the contrast in imaging studies for clearer visualisation of the area being examined.
