Combination products containing iothalamate
A combination is a different drug — different dosing, different warnings. It is listed here so you can find it, not so you can substitute it.
Iothalamate and breastfeeding
From LactMed, the US National Library of Medicine’s Drugs and Lactation Database — quoted, not rewritten.
Full LactMed record for iothalamate: levels in milk, effects in breastfed infants, and the drugs it would consider insteadIntravenous iodinated contrast media are poorly excreted into breastmilk and poorly absorbed orally so they are not likely to reach the bloodstream of the infant or cause any adverse effects in breastfed infants. Guidelines developed by several professional organizations state that breastfeeding need not be disrupted after a nursing mother receives an iodine-containing contrast medium. However, because there is no published experience with iothalamate during breastfeeding, other agents may be preferred, especially while nursing a newborn or preterm infant.
National Institute of Child Health and Human Development, record revised March 15, 2025. LactMed states its information is not a substitute for professional judgement.
What people report to the FDA about iothalamate
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1 reports naming iothalamate, and the FDA flagged 100% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- abdominal adhesions1 reports
- intestinal obstruction1 reports
Read these as a signal, not a rate. A report does not mean iothalamate caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
Can you take iothalamate with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run iothalamate against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What brand names is iothalamate sold under?
We track 2 iothalamate-containing products in the U.S.: Conray 325 and Conray 400. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does iothalamate come in?
Across the brands we track, iothalamate is currently marketed as injectable, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.

We do not currently list a generic-labelled iothalamate product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
