Levothyroxine Aristo (Anhydrous Levothyroxine Sodium)

Levothyroxine is a synthetic form of thyroxine (T4). After absorption, it is converted to the active hormone triiodothyronine (T3) within cells, binds to nuclear thyroid receptors, and modulates gene expression that controls basal metabolic rate, protein synthesis, and growth.

The appropriate dose is individualized and determined by the prescribing clinician based on the patient’s age, weight, severity of thyroid deficiency, and serial thyroid function test results. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Levothyroxine may be used during pregnancy or lactation only when clearly needed, as untreated hypothyroidism can harm both mother and fetus. The prescriber will weigh potential benefits against risks and may adjust the dose to maintain appropriate thyroid hormone levels.

Levothyroxine Aristo is a synthetic T4 formulation, similar to other levothyroxine products, and is generally preferred for stable, long‑term hormone replacement. Alternatives such as liothyronine (T3) act more rapidly but have a shorter half‑life and may require multiple daily doses, making levothyroxine the standard of care for most patients.

Store the tablets at ambient temperature, preferably below 25 °C, in the original container to protect them from moisture and light. Keep out of reach of children and do not use the product after the expiry date printed on the packaging.

Levothyroxine Aristo is taken orally, usually on an empty stomach with a full glass of water, at least 30 minutes before breakfast. Swallow the tablet whole; do not crush or chew it, and maintain consistent timing each day to ensure stable absorption.

Serious risks include cardiac arrhythmias, angina, myocardial infarction, and severe allergic reactions such as anaphylaxis. Patients with existing heart disease should be monitored closely, and any signs of chest pain, rapid heartbeat, or allergic symptoms require immediate medical attention.

Levothyroxine Aristo is contraindicated in patients with known hypersensitivity to levothyroxine or any of its excipients, untreated adrenal insufficiency, acute myocardial infarction, or uncontrolled thyrotoxicosis. Clinicians should assess medical history before initiating therapy.
