Drug interactions
There is no enhanced messaging for this drug.
There are no contraindication interactions for this drug.
Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
Agents That Affect Iodide/Radioactive Iodide
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Many compounds can affect iodide protein binding and alter iodide pharmacokinetics and pharmacodynamics.(1)
CLINICAL EFFECTS: Compounds that affect iodide pharmacokinetics and pharmacodynamics may impact the effectiveness of radioactive iodide.(1)
PREDISPOSING FACTORS: Compounds that affect iodide pharmacokinetics and pharmacodynamics are expected to have the most impact during therapy using radioactive iodide. Diagnostic procedures would be expected to be impacted less.
PATIENT MANAGEMENT: Discuss the use of agents that affect iodide pharmacokinetics and pharmacodynamics with the patient's oncologist.(1) Because indocyanine green contains sodium iodide, the iodine-binding capacity of thyroid tissue may be reduced for at least one week following administration. Do not perform radioactive iodine uptake studies for at least one week following administration of indocyanine green.(2) The manufacturer of iopamidol states administration may interfere with thyroid uptake of radioactive iodine and decrease therapeutic and diagnostic efficacy. Avoid thyroid therapy or testing for up to 6 weeks post administration of iopamidol.(3)
DISCUSSION: Many agents interact with radioactive iodine. The average duration of effect is: anticoagulants - 1 week antihistamines - 1 week anti-thyroid drugs, e.g: carbimazole, methimazole, propylthiouracil - 3-5 days corticosteroids - 1 week iodide-containing medications, e.g: amiodarone - 1-6 months expectorants - 2 weeks Lugol solution - 3 weeks saturated solution of potassium iodine - 3 weeks vitamins - 10-14 days iodide-containing X-ray contrast agents - up to 1 year lithium - 4 weeks phenylbutazone - 1-2 weeks sulfonamides - 1 week thyroid hormones (natural or synthetic), e.g.: thyroxine - 4 weeks tri-iodothyronine - 2 weeks tolbutamide - 1 week topical iodide - 1-9 months (1)
Agents That Affect Iodide/Sodium Iodide I 131
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Many compounds can affect iodide protein binding and alter iodide pharmacokinetics and pharmacodynamics.(1,2)
CLINICAL EFFECTS: Compounds that affect iodide pharmacokinetics and pharmacodynamics may impact the effectiveness of radioactive iodide.(1,2)

Ioflupane I 123/Dopamine Transporter Binders
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: Ioflupane binds to the dopamine transporter. Agents that also bind to this transporter may affect the results of single photon emission computed tomography (SPECT) brain imaging using ioflupane.(1)
CLINICAL EFFECTS: SPECT imaging using ioflupane may not be accurate in patients taking other drugs that bind to the dopamine transporter binders.(1)
PREDISPOSING FACTORS: None determined.
PATIENT MANAGEMENT: It is unknown if discontinuing other agents that bind to the dopamine transporter prior to a scan with ioflupane will decrease interference with the scan.(1) If use of these drugs can be safely suspended, consider discontinuing for at least 5 biological half-lives before administration of ioflupane.(1) Make sure the radiologist interpreting the scan knows the patient is taking another agent that binds to the dopamine transporter. Alternative diagnostic tools may need to be considered.
DISCUSSION: Ioflupane binds to the dopamine transporter. Agents that also bind to this transporter may affect the results of the scan. These agents include amoxapine, amphetamine, armodafinil, benztropine, bupropion, buspirone, citalopram, cocaine, dexmethylphenidate, escitalopram, fluoxetine, fluvoxamine, mazindol, methamphetamine, methylphenidate, modafinil, norephedrine, paroxetine, phentermine, phenylpropanolamine, selegiline, and sertraline.(1) In patients taking venlafaxine or desvenlafaxine, there have been cases of altered ioflupane uptake that impacted image interpretation. The mechanism of interference of these drugs with ioflupane is not known.(1)
