Natrio Jodidas [131i] Ge Healthcare (Sodium Iodide (131i))

Sodium Iodide‑131 mimics natural iodine and is taken up by thyroid cells via the sodium‑iodide symporter. The radioactive decay emits gamma photons that are captured by imaging equipment, providing a visual map of iodine uptake and thyroid activity.

The dose of Natrio Jodidas is determined by the prescribing physician based on the specific diagnostic protocol, patient weight, and clinical indication. The prescriber calculates the appropriate activity (in megabecquerels) to achieve optimal imaging quality while minimizing radiation exposure.

Use of radioactive iodine is generally contraindicated in pregnancy because the fetal thyroid can absorb the isotope, potentially causing damage. Breastfeeding mothers should discontinue nursing for a period recommended by the treating physician to avoid infant exposure.

To order Natrio Jodidas, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and necessary import documentation.

Natrio Jodidas (Sodium Iodide‑131) offers both imaging and a therapeutic radiation component, unlike non‑radioactive agents such as technetium‑99m pertechnetate, which provide only diagnostic information. The iodine‑131 tracer provides longer‑lasting radiation suitable for certain functional studies, but it also requires stricter radiation safety measures.

Store Natrio Jodidas at ambient temperature, preferably below 25 °C, in its original sealed container. Protect the product from moisture, direct sunlight, and physical damage. Follow all local regulations for handling radioactive materials, including using appropriate shielding and labeling.

Natrio Jodidas is administered orally as a single dose. The patient swallows the prescribed amount of the radiopharmaceutical, after which imaging is performed at a predetermined time interval to allow adequate thyroid uptake of the isotope.

Serious risks include radiation thyroiditis, acute hypothyroidism, bone marrow suppression, and, rarely, secondary malignancies due to radiation exposure. Patients should be monitored for signs of severe thyroid inflammation, abnormal blood counts, and any unexpected systemic symptoms.

Natrio Jodidas should be avoided in pregnant women, nursing mothers, patients with severe iodine allergy, and individuals who have recently received iodine‑containing contrast agents or high‑dose potassium iodide. It is also contraindicated in patients with uncontrolled hyperthyroidism unless specifically indicated by a specialist.
