Contrast Agents May Cause Underactive Thyroid. The U.S. Food and Drug Administration (FDA) has issued a safety alert noting that “rare cases of underactive thyroid have been reported in infants following the use of contrast media containing iodine also called ‘contrast dye,’ for X-rays and other medical imaging procedures.”
The agency stated that the infants were all premature or had other serious underlying health issues. The labels of all iodinated contrast media (ICM) will be updated to include information about the underactive thyroid cases.
The FDA believes the occurrence is rare and usually temporary without lasting side effects, according to the alert. But despite this news about this problem, authorities are looking forward to warn people against the use of similar products.
Contrast dye is used in medical imaging to visualize blood vessels
Contrast dye is used in medical imaging to visualize blood vessels and organs on medical images. It is utilized in medical imaging techniques such as X-ray and computed tomography (CT) scans.
If parents or caregivers are concerned, they should contact the child’s health care provider. Generally, an underactive thyroid will not present any visible symptoms in infants.
