Indications & Clinical Uses

Iodopol is used in nuclear medicine for conditions that involve the thyroid gland and related diagnostic or therapeutic pathways.

  • Thyroid imaging: enables visualization of thyroid tissue function and morphology.
  • Hyperthyroidism treatment: delivers targeted radiation to reduce excess thyroid hormone production.
  • Thyroid cancer ablation: used post‑surgery to eliminate residual thyroid tissue or metastatic disease.
  • Metastatic thyroid carcinoma: provides systemic radioactive iodine therapy to target distant lesions.

How It Works

  • Sodium Iodide‑131 is taken up by thyroid cells via the sodium‑iodide symporter. Once inside the gland, the radioisotope emits beta particles that cause localized cellular damage, while gamma emissions permit external imaging. This dual action allows both diagnostic visualization and therapeutic ablation of thyroid tissue.

Side Effects

Iodopol may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

  • Nausea or vomiting: transient gastrointestinal upset.
  • Dry mouth: reduced salivary flow after administration.
  • Taste alteration: metallic or altered taste perception.
  • Mild thyroid pain: localized discomfort in the neck region.
  • Transient hypothyroidism: temporary reduction in thyroid hormone levels.
  • Fatigue: general feeling of tiredness.

Serious or Rare Side Effects

  • Severe hypothyroidism: may require hormone replacement.
  • Bone marrow suppression: leading to decreased blood cell counts.
  • Allergic reaction: rash, itching, or anaphylaxis.
  • Radiation‑induced malignancy: potential long‑term cancer risk.
  • Salivary gland inflammation: sialadenitis causing swelling.
  • Pulmonary fibrosis: rare lung tissue scarring.

Precautions & Warnings

Before using Iodopol, consider the following safety measures.

  • Pregnancy assessment: avoid use in pregnant patients unless clearly indicated.
  • Breastfeeding guidance: discontinue breastfeeding during and after treatment as advised.
  • Thyroid function monitoring: check hormone levels before and after therapy.
  • Renal function evaluation: ensure adequate kidney function for clearance.
  • Iodine intake restriction: limit dietary iodine and avoid contrast agents.
  • Store at ambient temperature: keep in original container, protect from moisture and light.

Avoid Interactions

Iodopol can interact with other substances that affect iodine metabolism or radiation exposure.

Major Interactions (Avoid)

  • Concurrent radioactive iodine therapy: may cause cumulative radiation toxicity.
  • High‑iodine diet or supplements: reduces uptake of the drug.
  • Thyroid hormone suppressive therapy: can interfere with intended therapeutic effect.

Moderate Interactions (Monitor Closely)

  • Antithyroid medications (e.g., methimazole): may alter treatment outcomes.
  • Lithium therapy: can affect thyroid function and iodine handling.
  • Certain antibiotics (e.g., amiodarone): contain iodine and may compete for uptake.

Frequently Asked Questions

Iodopol contains Sodium Iodide‑131 and is used in nuclear medicine for thyroid imaging, treatment of hyperthyroidism, and ablation of thyroid cancer tissue. It provides both diagnostic visualization and therapeutic radiation to thyroid cells.

Sodium Iodide‑131 is actively taken up by thyroid cells via the sodium‑iodide symporter. Inside the gland, it emits beta particles that destroy targeted tissue while gamma emissions allow external imaging, enabling combined diagnostic and therapeutic effects.

The dose of Iodopol is determined by the prescribing physician based on the specific indication, patient characteristics, and diagnostic or therapeutic goals. Dosage is individualized and not standardized across all patients.

Iodopol is generally contraindicated in pregnancy because radioactive iodine can affect the developing fetus. Breastfeeding should be discontinued during treatment and for a period afterward as advised by the healthcare provider to avoid radiation exposure to the infant.

To order Iodopol, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Iodopol delivers radioactive iodine directly to thyroid tissue, offering a non‑surgical option for imaging and ablation. Compared with external beam radiation or surgery, it provides targeted therapy with less invasive administration, though suitability depends on disease stage and patient factors.

Iodopol should be stored at ambient temperature, below 25 °C, in its original packaging. Protect the product from moisture and direct light to maintain stability and potency.

Iodopol is administered orally as a solution or tablet, as directed by the prescriber. The patient swallows the dose with water, and the medication is absorbed systemically to reach the thyroid gland.

Serious risks include severe hypothyroidism requiring hormone replacement, bone marrow suppression leading to low blood counts, allergic reactions, and a long‑term risk of radiation‑induced malignancies. Patients should be monitored closely for these outcomes.

Iodopol should not be used by pregnant women, nursing mothers, patients with severe iodine allergy, or individuals who have recently received other radioactive iodine treatments unless specifically advised by a specialist.
