# Calcium Chloride 1% w/v + Potassium Iodide 3.3% w/v + Sodium Chloride 0.83% v/v ## SHORT DESCRIPTION Calcium Chloride 1% w/v + Potassium Iodide 3.3% w/v + Sodium Chloride 0.83% v/v is a **medicinal electrolyte and iodide-containing preparation**. The exact therapeutic use depends on the specific dosage form, route of administration and approved product labeling. Calcium chloride provides calcium, potassium iodide provides iodide, and sodium chloride contributes sodium and chloride. Because the listed concentrations may correspond to a specific formulation, the product should be used according to its manufacturer's instructions and a healthcare professional's advice. ## KEY BENEFITS * Provides **calcium ions** to the body * Provides **iodide** as an iodine source * Provides **sodium and chloride electrolytes** * May support correction or supplementation of specific electrolyte or iodine requirements when medically indicated * Can be useful when the individual components are clinically required in the prescribed formulation ## USES / INDICATIONS Depending on the specific formulation and approved indication, this combination may be used for: * Correction or supplementation of **calcium deficiency** * Providing iodide when iodine supplementation is medically required * Providing sodium and chloride electrolytes * Selected electrolyte-related conditions under professional supervision * Other specific indications stated on the product label **Important:** The indication cannot be determined from the ingredient concentrations alone. Check the product packaging or prescribing information for the approved use and route of administration. ## HOW IT WORKS ### Calcium Chloride Calcium is an essential electrolyte involved in: * Normal muscle contraction * Nerve transmission * Blood clotting * Cardiac function * Bone and teeth mineralization ### Potassium Iodide Potassium iodide supplies **iodide**, which is used by the thyroid gland to produce thyroid hormones. Iodide can also have specific medical uses depending on the dose and clinical situation. ### Sodium Chloride Sodium chloride supplies **sodium and chloride ions**, which contribute to fluid balance, electrolyte balance and normal nerve and muscle function. ## DOSAGE & ADMINISTRATION * Use only according to the **specific product label and healthcare professional's instructions**. * The appropriate dose depends on the formulation, indication, route of administration, age and medical condition. * Do not calculate or change the dose based solely on the percentages listed on the package. * If the product is intended for oral use, use the supplied measuring device where applicable. * If the product is intended for injection or another medical route, it should be administered only by appropriately trained healthcare professionals. * Do not self-administer an injectable preparation. * Do not exceed the recommended dose. ### Missed Dose If this product has been prescribed for regular use, follow your healthcare professional's instructions regarding a missed dose. Do not double the next dose unless specifically instructed. ## SIDE EFFECTS Possible side effects depend on the formulation and route of administration. Potential effects may include: * Nausea * Stomach discomfort * Vomiting * Unpleasant or metallic taste * Mild gastrointestinal irritation * Changes in electrolyte levels ### Calcium-Related Effects Excess calcium may cause: * Nausea * Vomiting * Constipation * Excessive thirst * Frequent urination * Weakness * Confusion * Abnormal heart rhythm in severe cases ### Iodide-Related Effects Excessive iodide exposure may cause: * Metallic taste * Increased salivation * Burning or irritation of the mouth or throat * Skin rash * Thyroid dysfunction Seek medical attention for severe allergic reactions, significant weakness, confusion, abnormal heartbeat or other serious symptoms. ## PRECAUTIONS & WARNINGS * Use only for the indication and route specified by the product. * Tell your doctor if you have **kidney disease**. * Tell your healthcare professional if you have a thyroid disorder. * Use caution if you have high blood calcium levels or a history of kidney stones. * Inform your doctor if you have heart disease or an abnormal heart rhythm. * Excessive iodine intake can cause thyroid dysfunction in susceptible individuals. * People with certain thyroid conditions may be particularly sensitive to excess iodide. * Avoid taking additional iodine-containing supplements unless recommended. * Tell your doctor about all electrolyte, vitamin and mineral supplements you use. * If the formulation is injectable, administration should be performed by trained medical personnel because calcium-containing injections can cause serious tissue injury if administered incorrectly. * Keep out of reach of children. * Seek medical advice if symptoms of electrolyte imbalance occur. ## DRUG INTERACTIONS Potential interactions depend on the formulation and route of administration. Important medicines and substances that may require medical review include: * **Digoxin and other cardiac glycosides** — abnormal calcium levels can affect cardiac effects and rhythm. * **Thiazide diuretics** — may increase calcium levels. * **Lithium** — iodine and thyroid effects may be clinically relevant in some patients. * **Antithyroid medicines** — additional iodide may affect thyroid treatment. * **ACE inhibitors, ARBs or potassium-containing products** — potassium iodide may contribute potassium intake and may require consideration in susceptible patients. * **Other calcium supplements** — may increase the risk of excessive calcium intake. * **Iodine-containing medicines or supplements** — may increase total iodine exposure. * **Certain medicines affected by electrolyte changes** may require monitoring. Always tell your doctor or pharmacist about prescription medicines, over-the-counter medicines, vitamins, minerals and herbal supplements you are taking. ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep in the original container. * Store at the recommended temperature. * Protect from excessive heat, moisture and direct sunlight. * Keep the container tightly closed where applicable. * Do not freeze unless specifically instructed by the manufacturer. * Keep out of reach of children. * Do not use after the expiry date. * Do not use if the product appears discolored, contaminated or if the packaging is damaged. ## PRESCRIPTION STATUS **Prescription status depends on the specific formulation, route of administration and country.** Because calcium chloride and concentrated iodide preparations may require professional supervision, use the product only according to the manufacturer's labeling and advice from a qualified healthcare professional. ## GENUINE MEDICINE ASSURANCE For safe and genuine medicine use: * Purchase the product from a licensed and reputable pharmacy. * Verify the exact ingredient strengths and formulation. * Check the batch number and expiry date. * Ensure the container and seal are intact. * Check the manufacturer's name and details. * Avoid products with damaged, altered or suspicious packaging. * Follow the storage instructions on the package. * Consult a pharmacist if you have concerns about authenticity. ## FAQ ### What is Calcium Chloride + Potassium Iodide + Sodium Chloride used for?
