Introduction to Deferasirox Tablets and their Variants
Deferasirox, available under various brand names including Desirox, Exjade, and Jadenu, is an orally administered iron-chelating agent used to manage chronic Iron Overload conditions resulting from transfusion-dependent disorders such as Thalassemia and certain anemias. Its mechanism of action involves binding to excess iron, allowing for its elimination from the body through urine and feces. The availability of Deferasirox in different formulations provides flexibility in dosing and enhances patient compliance.
What is Deferasirox?
Deferasirox is a pharmaceutical agent used for managing chronic iron overload conditions. It acts as an iron-chelating agent, binding to excess iron in the body and aiding its elimination. Deferasirox is available in various formulations and dosages, offering flexibility in treatment.
Dosage Information
Initial Dosage: The recommended starting dose of Deferasirox varies based on the patient's baseline serum ferritin level and weight. For patients with serum ferritin levels <1,000 mcg/L, the standard starting dose is 20 mg/kg once daily. For those with higher levels, the initial dose may be increased to 30 mg/kg.
Deferasirox 500mg Tablet:
Deferasirox is commonly available in tablet form, including the Deferasirox 500mg Tablet variant. This specific dosage allows for precise administration of the medication. The 500mg tablet is often used based on patient weight and iron burden levels, as determined by healthcare professionals.
Dose Titration: Regular monitoring of serum ferritin levels is crucial. The dose should be titrated based on response and tolerance, aiming to reduce ferritin levels while avoiding excessive iron depletion. Adjustments are typically made in increments of 5 to 10 mg/kg.
Missed Dose: If a dose is missed, it should be taken as soon as remembered unless it is close to the time for the next scheduled dose. In such cases, the missed dose should be skipped and the regular dosing schedule resumed. Doubling the dose to make up for a missed one should be avoided.
Overdose: In cases of overdose, monitoring for signs of toxicity is essential. Overdosing may lead to increased adverse effects, such as gastrointestinal disturbances, liver function abnormalities, and kidney problems. Prompt medical attention is crucial if an overdose is suspected.
Discontinuation: Deferasirox treatment should not be abruptly discontinued. Gradual tapering may be necessary under the supervision of a healthcare provider, especially if the patient's iron levels are well-managed.
