L-Thyroxin Tropfen Henning (Levothyroxine Sodium)

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

The appropriate dose is individualized by the prescribing clinician based on the patient’s age, weight, severity of hormone deficiency and laboratory thyroid function tests. Dosage adjustments are made during follow‑up to achieve target TSH levels.

Levothyroxine is the treatment of choice for hypothyroidism in pregnancy because adequate thyroid hormone is essential for fetal neurodevelopment. It is generally considered safe when used at the dose required to maintain normal maternal thyroid function. Breastfeeding mothers should continue therapy under medical supervision.

The primary alternative is liothyronine (T3) which has a faster onset but a shorter half‑life. Levothyroxine (T4) provides a more stable, long‑acting replacement and is the standard of care for most hypothyroid patients. Choice depends on clinical response, patient preference and specific endocrine goals.

Store the oral drops at ambient temperature, preferably below 25 °C, in the original container to protect from moisture and light. Keep the bottle tightly closed and out of reach of children. Do not freeze or expose to extreme heat.

The product is an oral solution delivered in drop form. The prescribed number of drops is measured with the supplied calibrated dropper and taken once daily, preferably on an empty stomach 30‑60 minutes before breakfast, unless the prescriber advises otherwise.

Serious risks include cardiac arrhythmias, angina pectoris, and overt hyperthyroidism, which can lead to symptoms such as rapid heart rate, heat intolerance and anxiety. Long‑term overtreatment may also increase the risk of osteoporosis, especially in post‑menopausal women.

Patients with known hypersensitivity to levothyroxine or any excipients in the formulation should avoid the product. Caution is advised in individuals with untreated adrenal insufficiency, acute myocardial infarction, or severe cardiovascular disease, where rapid dose escalation could be hazardous.
