Jodid (Potassium Iodide)

Potassium Iodide, the active ingredient in Jodid, is an iodide supplement presented as an oral tablet for oral use. It is employed to protect the thyroid gland from radioactive iodine uptake and to prevent iodine deficiency in the general population.

GNH India supplies Jodid as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory documentation to support import and distribution across multiple regions. This enables reliable access to essential iodine prophylaxis for emergency preparedness and routine health programs.

Indications & Clinical Uses

  • Jodid is an iodide supplement that acts on thyroid iodine uptake pathways.
  • Radiation emergency exposure: reduces thyroid absorption of radioactive iodine, lowering risk of thyroid cancer.
  • Iodine deficiency: supplies stable iodide ions to meet dietary requirements and support normal thyroid hormone synthesis.
  • Nuclear medicine procedures: prevents uptake of diagnostic iodine isotopes, protecting thyroid function during imaging.

How It Works

  • Potassium iodide provides a high concentration of stable iodide ions that are rapidly absorbed from the gastrointestinal tract. The excess iodide saturates the sodium‑iodide symporter in thyroid follicular cells, temporarily inhibiting further iodide uptake. By occupying the transport mechanism, it blocks incorporation of radioactive iodine isotopes into thyroid hormone, thereby protecting thyroid tissue during exposure. The effect persists for several hours, after which normal iodide transport resumes.

Side Effects

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

Common Side Effects

  • Metallic or salty taste in the mouth.
  • Nausea, vomiting or mild abdominal discomfort.
  • Diarrhea or loose stools.
  • Mild skin rash or itching.

Serious or Rare Side Effects

  • Iodide‑induced thyroid dysfunction (hypo‑ or hyperthyroidism).
  • Severe allergic reaction, including anaphylaxis.
  • Iodism, a systemic toxicity presenting with fever, headache and lethargy.

Precautions & Warnings

When using Jodid, several precautions should be observed to ensure safety and effectiveness.

  • Assess iodine status before use: determine if supplementation is necessary to avoid excess intake.
  • Avoid in known hypersensitivity: discontinue if allergic reaction occurs.
  • Use with caution in thyroid disorders: monitor thyroid function in patients with hyper‑ or hypothyroidism.
  • Do not exceed recommended dose: follow prescriber instructions to prevent iodide toxicity.
  • Pregnant or breastfeeding women: consult healthcare professional before use.
  • Store at room temperature: keep in original container, protect from moisture and direct sunlight.

Avoid Interactions

Potassium iodide can interact with certain medications, altering their efficacy or safety.

Major Interactions (Avoid)

  • Levothyroxine therapy: iodide may reduce absorption and effectiveness of thyroid hormone replacement.
  • Amiodarone: combined iodine load can exacerbate thyroid dysfunction.
  • Lithium: concurrent use may increase risk of thyroid abnormalities.

Moderate Interactions (Monitor Closely)

  • Loop and thiazide diuretics: may affect potassium balance when high iodide intake occurs.
  • ACE inhibitors: potential for hyperkalemia requires monitoring.
  • Antacids containing aluminum or magnesium: may decrease iodide absorption, reducing prophylactic benefit.

Frequently Asked Questions

Jodid contains potassium iodide and is used to protect the thyroid gland from uptake of radioactive iodine during nuclear incidents or medical procedures, and to prevent iodine deficiency in individuals who lack adequate dietary iodine.

Potassium iodide supplies a large amount of stable iodide ions that saturate the thyroid’s sodium‑iodide symporter, temporarily blocking the gland’s ability to take up additional iodine, including harmful radioactive isotopes.

The appropriate dose of Jodid is determined by a qualified healthcare professional based on the specific indication, patient age, weight and exposure risk. Patients should follow the prescriber’s instructions and not self‑adjust the dosage.

Safety of potassium iodide in pregnancy or lactation has not been definitively established. Women who are pregnant, planning pregnancy, or breastfeeding should discuss potential benefits and risks with their healthcare provider before using Jodid.

To order Jodid, 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 required import documentation.

Jodid provides potassium iodide, the standard oral iodide supplement recommended by health authorities for thyroid protection. Alternative forms such as potassium iodate deliver iodine but are less commonly used for emergency prophylaxis due to differing pharmacokinetics and regulatory guidance.

Jodid should be stored at room temperature, below 25 °C, in its original packaging. Keep the container tightly closed, protect it from moisture, heat and direct sunlight to maintain stability and potency.

Jodid is taken orally, usually as a tablet, with a glass of water. The exact timing relative to a potential radioactive exposure is determined by medical guidance; it is typically taken as soon as possible after exposure risk is identified.

Serious risks include iodide‑induced thyroid dysfunction (both hypo‑ and hyperthyroidism), severe allergic reactions such as anaphylaxis, and iodism, a systemic toxicity that can cause fever, headache and lethargy. Prompt medical attention is required if these occur.

Individuals with known hypersensitivity to potassium iodide, those with certain thyroid disorders (e.g., untreated hyperthyroidism) without medical supervision, and patients on medications that may interact severely (such as levothyroxine, amiodarone or lithium) should avoid Jodid unless directed by a healthcare professional.
