• > **High Toxicity Potential:** Clinical experience in veterinary patients is limited. Use only when other less toxic and more commonly used drugs are ineffective. * **Hepatic Effects:** Hepatopathy can occur before clinical signs are noted; routine serial evaluation of liver enzymes and bilirubin is strongly recommended. * **Thyroid Function:** May alter thyroid hormone levels (increases T4 and reverse T3, decreases T3) due to high iodine content. * **Pregnancy:** FDA Category D. Embryotoxic in laboratory animals; congenital thyroid abnormalities detected in offspring. Use only if benefits outweigh risks.
