THYRONORM 62.5

# Thyroxine 62.5 mcg ## Short Description **Thyroxine 62.5 mcg (levothyroxine)** is a synthetic form of the thyroid hormone **thyroxine (T4)**. It is primarily used as **thyroid hormone replacement therapy** in people whose thyroid gland does not produce enough thyroid hormone. Levothyroxine helps restore normal thyroid hormone levels and can relieve symptoms associated with **hypothyroidism** when the correct dose is taken regularly. > **Important:** Levothyroxine has a narrow therapeutic range. The dose should be individualized based on thyroid blood tests, clinical symptoms, age, and other health conditions. --- # Key Benefits * Replaces deficient **thyroid hormone (T4)**. * Helps restore normal thyroid hormone levels. * Helps relieve symptoms of hypothyroidism. * Supports normal metabolism and energy production. * Supports normal heart, brain, muscle, and digestive function. * Helps maintain normal growth and development in children when thyroid hormone is deficient. * Can help prevent complications of untreated hypothyroidism. --- # Uses / Indications ### 1. Hypothyroidism Thyroxine 62.5 mcg is commonly prescribed for **underactive thyroid (hypothyroidism)** caused by conditions such as: * Hashimoto's thyroiditis * Autoimmune thyroid disease * Thyroid surgery * Radioactive iodine treatment * Certain medicines * Congenital thyroid hormone deficiency ### 2. Thyroid Hormone Replacement It replaces the thyroid hormone that the body is unable to produce adequately. ### 3. Thyroid Cancer In selected patients with thyroid cancer, levothyroxine may be prescribed at doses intended to **suppress thyroid-stimulating hormone (TSH)** as part of specialist treatment. ### 4. Goiter Levothyroxine may sometimes be used in specific thyroid disorders or goiter management when clinically appropriate. --- # How It Works Thyroxine (levothyroxine) is a synthetic version of the body's naturally produced **T4 thyroid hormone**. After absorption, some T4 is converted into **triiodothyronine (T3)**, the more biologically active thyroid hormone. Thyroid hormones regulate numerous processes, including: * Metabolism * Energy production * Heart function * Body temperature * Brain function * Muscle function * Growth and development Levothyroxine restores thyroid hormone activity and helps bring **TSH and thyroid hormone levels toward the desired range**. --- # Dosage & Administration The appropriate dose is individualized. **Thyroxine 62.5 mcg is one possible maintenance dose and is not appropriate for everyone.** Your healthcare professional may adjust the dose based on: * TSH and free T4 blood tests * Age * Body weight * Cause and severity of hypothyroidism * Pregnancy * Heart disease * Other medicines ### How to Take Thyroxine * Take it **once daily**, unless otherwise prescribed. * Take it on an **empty stomach**, ideally **30–60 minutes before breakfast**. * Take it with a full glass of water. * Try to take it at the same time every day. * Avoid switching between different brands or formulations without discussing it with your healthcare professional, as absorption can vary. ### Alternative Timing If morning administration is difficult, levothyroxine may sometimes be taken consistently at bedtime, provided it is taken several hours after the last meal. Follow your doctor's specific instructions. ### Important: Calcium and Iron Calcium and iron supplements can significantly reduce levothyroxine absorption. Separate levothyroxine from calcium or iron supplements by **at least 4 hours**, unless your healthcare professional provides different instructions. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. If it is close to the next scheduled dose, skip the missed dose. **Do not routinely double the dose without medical advice.** --- # Side Effects When the correct dose is used, levothyroxine is generally well tolerated. Side effects are often associated with receiving **too much thyroid hormone**. ## Common Signs of Excess Thyroid Hormone * Increased heart rate * Palpitations * Nervousness * Anxiety * Tremor * Sweating * Heat intolerance * Headache * Difficulty sleeping * Increased appetite * Weight loss * Diarrhea * Muscle weakness ## Serious Side Effects Seek medical attention for: * Chest pain * Severe or persistent palpitations * Very rapid or irregular heartbeat * Shortness of breath * Severe tremor * Fainting * Severe headache or confusion Long-term excessive dosing can increase the risk of **abnormal heart rhythms and reduced bone mineral density**. --- # Precautions & Warnings ### Correct Dose Is Important Levothyroxine is a hormone replacement medicine, and both **too little and too much** can cause problems. Do not change your dose based only on symptoms. ### Heart Disease People with: * Coronary artery disease * Angina * Previous heart attack * Heart rhythm disorders * Other cardiovascular disease may require a lower starting dose and gradual dose adjustment. ### Adrenal Insufficiency Untreated adrenal insufficiency should be considered before starting thyroid hormone replacement because thyroid hormone treatment can worsen adrenal insufficiency in susceptible individuals. ### Osteoporosis Long-term excessive thyroid hormone replacement can contribute to bone loss, particularly in postmenopausal individuals. ### Pregnancy Thyroid hormone requirements often **increase during pregnancy**. Women taking levothyroxine who become pregnant should contact their healthcare professional promptly for appropriate thyroid monitoring and dose adjustment. Do not stop levothyroxine during pregnancy without medical advice. ### Children Levothyroxine is commonly used in children with hypothyroidism, but dosing is carefully individualized according to age, weight, and clinical requirements. ### Older Adults Older adults, particularly those with heart disease, may require cautious dose initiation and monitoring. --- # Drug Interactions ### Calcium Supplements Calcium can reduce levothyroxine absorption. **Separate calcium-containing products from levothyroxine by at least 4 hours.** ### Iron Supplements Iron can reduce absorption. Separate iron-containing supplements from levothyroxine by **at least 4 hours**. ### Antacids Some antacids containing: * Aluminum * Magnesium * Calcium can reduce levothyroxine absorption. ### Proton Pump Inhibitors Medicines such as omeprazole and other acid-reducing medicines may affect levothyroxine absorption in some patients. ### Cholestyramine and Similar Medicines Bile-acid sequestrants can reduce levothyroxine absorption. ### Certain Foods and Beverages Absorption may be affected by: * Soy-containing foods * High-fiber diets * Coffee * Certain mineral-containing foods or supplements Consistent administration is important. ### Warfarin Starting or changing thyroid hormone therapy can alter the response to **warfarin**, potentially requiring closer monitoring of anticoagulation. ### Diabetes Medicines Thyroid hormone changes can affect blood glucose control and may require adjustment of diabetes medicines.
