Natriumjodid (131i) Diagnostikkapseln Ge Healthcare (Sodium Iodide (131i))

Sodium Iodide, the active ingredient in Natriumjodid (131i) Diagnostikkapseln, is a diagnostic radiopharmaceutical presented as a capsule for oral use. It is employed to image thyroid tissue and assess thyroid function in patients undergoing diagnostic evaluation.

GNH USA supplies Natriumjodid (131i) Diagnostikkapseln as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide. The product conforms to EU regulatory standards and is manufactured under GMP conditions.

Natriumjodid (131i) Diagnostikkapseln is a radioactive iodine preparation used in thyroid imaging and functional assessment.

Thyroid imaging: enables visualization of thyroid anatomy and iodine uptake for diagnostic interpretation. Hyperthyroidism evaluation: helps quantify functional activity of overactive thyroid tissue to guide management. Thyroid nodule assessment: differentiates benign from malignant nodules based on iodine uptake patterns.

Administration of I‑131 sodium iodide may be associated with several adverse reactions, ranging from mild, transient symptoms to rare but serious radiation‑related events.

Common Side Effects: - Nausea: mild, transient feeling of sickness. - Abdominal discomfort: mild pain or cramping in the stomach area. - Taste alteration: temporary metallic or altered taste perception. - Headache: mild, transient head pain.

Serious or Rare Side Effects: - Allergic reaction (anaphylaxis): severe hypersensitivity that may require emergency treatment. - Radiation thyroiditis: inflammation of thyroid tissue due to radiation exposure. - Bone marrow suppression (rare): decreased blood cell production, potentially leading to anemia or infection. - Pulmonary radiation pneumonitis (very rare): inflammation of lung tissue after high radiation exposure.

Prior to using Natriumjodid (131i) Diagnostikkapseln, several safety considerations should be observed. - Pregnancy: avoid use unless clearly indicated, as fetal radiation exposure is possible. - Breastfeeding: discontinue product and consider alternative imaging; iodine can be secreted in milk. - Thyroid function: assess baseline thyroid status before administration to interpret results accurately. - Renal impairment: evaluate kidney function, as excretion may be altered. - Radiation safety: limit exposure of staff and family members; follow institutional radiation protection guidelines. - Store at ambient temperature: keep capsules in original packaging, protect from moisture and light.

I‑131 sodium iodide can interact with other agents that affect iodine metabolism or radiation exposure.

Major Interactions (Avoid): - Concomitant radioactive iodine therapy: cumulative radiation dose may exceed safety limits. - High‑dose levothyroxine therapy: suppresses thyroid uptake, reducing diagnostic efficacy.

Moderate Interactions (Monitor Closely): - Antithyroid drugs (methimazole, propylthiouracil): may decrease iodine uptake, affecting image quality. - Iodinated contrast agents: can interfere with thyroid uptake if administered within two weeks. - Lithium therapy: alters thyroid iodine handling, potentially modifying imaging results.
