Ipodate Sodium
Also known as: Solu-Biloptin, Solubiloptine, Bilivist, Biloptin, Oragrafin
**What is this medication?** Ipodate is used to manage hyperthyroidism (an overactive thyroid gland) in cats, usually when standard medications like methimazole cause unacceptable side effects. **Important points for pet owners:** * **Not a Cure:** This drug decreases the effects of excessive thyroid hormones but does not cure the underlying condition. Strict compliance with daily dosing is necessary for success. * **Fading Effectiveness:** The long-term effectiveness of this drug is questionable. Many cats become "refractory" to it, meaning the drug may stop working after a few months. * **Monitoring is Different:** Unlike standard thyroid medications, your veterinarian will monitor your cat's weight, heart rate, and a specific thyroid hormone called **T3** (instead of the usual T4). * **Compounding Required:** Because this medication is not commercially manufactured, it must be specially made (compounded) by a veterinary pharmacy. * **Side Effects:** Watch for signs of stomach upset, such as vomiting, diarrhea, or loss of appetite. Contact your veterinarian if these occur.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

- Pregnancy (risk of congenital hypothyroidism in fetuses)
- Use with caution in patients who have had previous hypersensitivity reactions to iodine compounds. In humans, multiple doses are contraindicated in patients with hepatic dysfunction due to reports of renal toxicity. Use with caution in patients with hyperuricemia due to the possibility of uric acid nephropathy. **Laboratory Interferences:** * May increase BSP retention times and serum bilirubin levels. * May cause false-positive urine protein determinations. * Interferes with thyroid scanning.
Drug interactions
- Radioactive Iodine (I-131): Ipodate may interfere with radioactive iodine uptake and therapy. It is recommended to discontinue ipodate at least 2 weeks (preferably 3-4 weeks or more) prior to I-131 treatment.
