Radioactive Iodine

9 interactions on record

Radioactive Iodine has 9 known drug interactions based on U.S. FDA drug labeling data. 6 are classified as major interactions requiring close medical supervision. Notable interactions include combinations with Betamethasone Sodium Phosphate, Betamethasone Acetate, Lidocaine, Iodixanol, Povidine Iodine, Iodixanol, Iohexol. Patients taking Radioactive Iodine should inform their healthcare provider of all current medications — including over-the-counter drugs and supplements — to avoid potentially harmful combinations.

Radioactive Iodine + Betamethasone Sodium Phosphate, Betamethasone Acetate, Lidocaine, Iodixanol, Povidine Iodine⚠️Major

Iodixanol may interfere with thyroid uptake of radioactive iodine (I-131, I-123), decreasing therapeutic and diagnostic efficacy in thyroid carcinoma patients for 6-8 weeks.

Radioactive Iodine + Iodixanol⚠️Major

Iodixanol may interfere with thyroid uptake of radioactive iodine (I-131 and I-123), decreasing therapeutic and diagnostic efficacy in thyroid carcinoma patients for 6 to 8 weeks.

Radioactive Iodine + Iohexol⚠️Major

IOHEXOL may interfere with thyroid uptake of radioactive iodine (I-131 and I-123), decreasing therapeutic and diagnostic efficacy. Avoid thyroid therapy or testing for up to 6 weeks post-IOHEXOL administration.

Radioactive Iodine + Iopamidol⚠️Major

Iopamidol may interfere with thyroid uptake of radioactive iodine (I-131 and I-123), decreasing therapeutic and diagnostic efficacy. Avoid thyroid therapy or testing for up to 6 weeks post iopamidol injection.

Radioactive Iodine + Ioversol⚠️Major

Iodinated contrast agents interfere with thyroid uptake of radioactive iodine (I-131) and decrease therapeutic efficacy in thyroid carcinoma patients. Decreased efficacy lasts 6-8 weeks.

Radioactive Iodine + Levothyroxine Sodium⚠️Major

May decrease thyroid hormone secretion or cause hyperthyroidism; parenteral agents produce more prolonged hypothyroidism than oral agents.

Radioactive Iodine + Indocyanine Green🟡Moderate

IC-GREEN contains sodium iodide which reduces iodine-binding capacity of thyroid tissue for at least one week, interfering with radioactive iodine uptake studies. Do not perform studies within one week of IC-GREEN administration.

Radioactive Iodine + Iomeprol Injection🟡Moderate

Avoid thyroid therapy or testing using radioactive iodine for up to 6 weeks post-IOMERVU. IOMERVU may interfere with thyroid uptake of radioactive iodine and decrease therapeutic and diagnostic efficacy.

Radioactive Iodine + Iopromide🟡Moderate

IOPROMIDE may interfere with thyroid uptake of radioactive iodine (I-131 and I-123), decreasing therapeutic and diagnostic efficacy. Avoid thyroid therapy or testing for up to 6 weeks post-IOPROMIDE.
