Previous IV iodinated contrast reaction

Sometimes people will have a reaction to the IV iodinated contrast. Depending on the severity of the sensitivity, a course of premedication could possibly be given to the person prior the injection to help reduce the likelyhood of another reaction. If your patient has had an iodine reaction, contact one of our radiologists to discuss the previous reaction and the options available.

 

 

IV iodinated contrast injection for diabetic patients

People who are diabetic and are controlling their diabeties via tablets containing metformin, must cease taking the metformin on the day of the injection and for 48 hours afterwards.

 

The adminstration of IV iodinated contrast to patients receiving metformin therapy can place them at a higher risk of causing lactic acidosis*. Patients using metformin should have a blood test following the day of the examination to assess renal function post an injection of IV iodinated contrast.

 

A person's creatine level should be below 110µmol/L for males and 100µmol/L for females for the safe use of IV iodinated contrast. To discuss options for people with higher creatine levels needing IV iodinated contrast, such as the use of pre-hydration, please don't hesitate to contact one of our radiologists.
