THYRONORM 125MCG

# Thyroxine 125 mcg ## SHORT DESCRIPTION Thyroxine 125 mcg, also known as **levothyroxine 125 mcg**, is a thyroid hormone replacement medicine used to treat **hypothyroidism**, a condition in which the thyroid gland does not produce enough thyroid hormone. It is a synthetic form of thyroxine (T4) and helps restore normal thyroid hormone levels in the body. The dose is individualized based on thyroid function tests, age, medical conditions, and response to treatment. ## KEY BENEFITS * Replaces insufficient thyroid hormone * Helps restore normal thyroid hormone levels * Helps relieve symptoms associated with hypothyroidism * Supports normal metabolism and energy production * Supports normal heart, muscle, and nervous-system function * Helps maintain normal growth and development when appropriately prescribed * Can be used for long-term thyroid hormone replacement ## USES / INDICATIONS Thyroxine 125 mcg may be prescribed for: * **Hypothyroidism** * Primary thyroid hormone deficiency * Certain cases of hypothyroidism following thyroid surgery * Hypothyroidism following radioactive iodine treatment * Thyroid hormone replacement after partial or complete thyroid removal * Certain cases of congenital hypothyroidism * Thyroid hormone suppression therapy in selected thyroid disorders, when specifically prescribed The 125 mcg strength is not suitable for everyone. Your required dose is determined using thyroid function tests and individual clinical factors. ## HOW IT WORKS Thyroxine (levothyroxine) is a synthetic form of the naturally occurring thyroid hormone **T4**. After administration, T4 is converted in the body to **triiodothyronine (T3)**, the more biologically active thyroid hormone. T3 and T4 regulate metabolism, energy use, body temperature, heart function, and many other physiological processes. Taking levothyroxine replaces the thyroid hormone that the body is unable to produce adequately. ## DOSAGE & ADMINISTRATION * Take Thyroxine 125 mcg exactly as prescribed by your doctor. * It is usually taken **once daily on an empty stomach**, preferably 30–60 minutes before breakfast. * Take it with a full glass of water. * Take it at the same time every day. * Avoid taking calcium, iron, magnesium-containing supplements, or certain antacids at the same time because they can reduce levothyroxine absorption. * A consistent dosing routine is important. * Do not change the dose based on symptoms alone. * Your doctor may periodically check **TSH and other thyroid function tests** and adjust the dose. * Do not stop treatment suddenly unless instructed by your healthcare professional. * If you miss a dose, take it when remembered unless it is close to the next scheduled dose. Do not routinely double doses without medical advice. ## SIDE EFFECTS When the dose is appropriate, levothyroxine is generally well tolerated. Side effects usually occur when the dose is **too high** and may include symptoms similar to an overactive thyroid: * Increased heartbeat * Palpitations * Nervousness * Anxiety * Tremor * Sweating * Heat intolerance * Headache * Difficulty sleeping * Increased appetite * Weight loss * Diarrhoea * Muscle weakness Excessive thyroid hormone replacement can also increase the risk of **irregular heart rhythms and bone loss**, particularly with long-term overtreatment. Seek medical attention for severe chest pain, marked palpitations, fainting, or significant shortness of breath. ## PRECAUTIONS & WARNINGS * Take levothyroxine exactly as prescribed. **Do not adjust the dose yourself.** * Tell your doctor if you have heart disease, angina, high blood pressure, or an abnormal heart rhythm. * Older adults may require a lower starting dose and careful monitoring. * Inform your doctor if you have adrenal insufficiency. * Regular thyroid blood tests are important to ensure the dose is appropriate. * Changes in brand or formulation may affect thyroid hormone control in some patients. Inform your doctor if your product is changed. * Take the medicine consistently in relation to food. * Do not take extra doses to treat tiredness or weight gain without medical advice. * Inform your doctor if you are pregnant or planning pregnancy, as thyroid hormone requirements may increase during pregnancy. * Tell your healthcare professional about any major changes in your health, weight, diet, or other medicines. ## DRUG INTERACTIONS Levothyroxine interacts with several medicines and supplements that can affect absorption or thyroid hormone activity. Important interactions include: * **Calcium supplements** — can reduce levothyroxine absorption. * **Iron supplements** — can reduce absorption. * Magnesium-containing antacids or supplements — may reduce absorption. * Aluminium-containing antacids — may reduce absorption. * Certain cholesterol-lowering medicines such as bile-acid sequestrants — can reduce absorption. * Proton-pump inhibitors and other medicines that alter stomach acidity may affect absorption in some patients. * **Warfarin** — thyroid hormone replacement can alter anticoagulant requirements. * Certain diabetes medicines — thyroid hormone changes may affect blood glucose control. * Some anticonvulsants and other medicines can alter thyroid hormone metabolism. Calcium and iron supplements are commonly separated from levothyroxine by **at least 4 hours**, unless your healthcare professional gives different instructions. Always inform your doctor or pharmacist about all prescription medicines, over-the-counter medicines, vitamins, and supplements you take. ## STORAGE INFORMATION * Store Thyroxine 125 mcg according to the manufacturer's instructions. * Keep at room temperature. * Protect from moisture, excessive heat, and direct sunlight. * Keep the tablets in their original packaging. * Keep the container tightly closed when not in use. * Keep out of reach and sight of children. * Do not use after the expiry date. * Avoid storing the medicine in areas with excessive humidity, such as bathrooms. ## PRESCRIPTION STATUS Thyroxine 125 mcg is generally a **prescription medicine** and should be taken under medical supervision.
