THYROLAR 12.5MG

# Levothyroxine 12.5 mcg ## SHORT DESCRIPTION Levothyroxine 12.5 mcg is a synthetic form of thyroxine (T4), a hormone normally produced by the thyroid gland. It is used as thyroid hormone replacement in people whose thyroid gland does not produce enough thyroid hormone. It is commonly prescribed for hypothyroidism and may also be used in certain thyroid-related conditions under medical supervision. ## KEY BENEFITS * Replaces thyroid hormone that the body is unable to produce adequately * Helps restore normal thyroid hormone levels * Supports normal metabolism and energy production * Helps relieve symptoms associated with hypothyroidism * Supports normal heart, brain, muscle, and digestive function * May help maintain normal growth and development when thyroid hormone deficiency is present ## USES / INDICATIONS Levothyroxine 12.5 mcg may be used for: * Hypothyroidism * Thyroid hormone replacement after certain thyroid surgeries * Thyroid hormone deficiency following treatment for some thyroid disorders * Certain cases of goitre, when prescribed by a healthcare professional * Thyroid hormone suppression therapy in selected thyroid conditions ## HOW IT WORKS Levothyroxine is a synthetic form of thyroxine (T4), the primary hormone produced by the thyroid gland. After administration, it is converted in the body to the more active thyroid hormone triiodothyronine (T3). It binds to thyroid hormone receptors and helps regulate metabolism, energy use, body temperature, heart function, and other important physiological processes. ## DOSAGE & ADMINISTRATION * Take Levothyroxine exactly as prescribed by your doctor. * It is generally taken **once daily on an empty stomach**, preferably 30–60 minutes before breakfast. * Take it with a full glass of water. * Take it consistently at the same time each day. * Swallow the tablet whole unless your healthcare professional gives different instructions. * Do not change the dose or stop treatment without consulting your doctor. * Your doctor may adjust the dose based on thyroid function blood tests, particularly TSH and sometimes free T4. * Maintain a consistent routine if you take medicines or supplements that can affect levothyroxine absorption. ## SIDE EFFECTS Side effects are more likely when the dose is higher than the body's requirement. Possible symptoms include: * Increased heartbeat or palpitations * Nervousness or anxiety * Trembling * Increased sweating * Heat intolerance * Headache * Difficulty sleeping * Increased appetite * Weight loss * Diarrhoea * Muscle weakness * Menstrual changes Seek medical attention for severe chest pain, significant palpitations, shortness of breath, or other serious symptoms. ## PRECAUTIONS & WARNINGS * Levothyroxine should be used under medical supervision. * Do not use it to treat obesity or for weight loss. * Tell your doctor if you have heart disease, high blood pressure, diabetes, adrenal gland problems, or other medical conditions. * Dose adjustments may be necessary in older adults and people with cardiovascular disease. * Inform your doctor if you are pregnant or planning pregnancy because thyroid hormone requirements may change during pregnancy. * Do not discontinue levothyroxine suddenly without medical advice. * Regular thyroid function testing may be required to ensure that the dose is appropriate. * Excessive thyroid hormone replacement can cause symptoms of hyperthyroidism and may increase the risk of heart rhythm problems or bone loss with long-term overtreatment. ## DRUG INTERACTIONS Levothyroxine absorption or effectiveness may be affected by several medicines and supplements, including: * Calcium supplements * Iron supplements * Antacids containing aluminium or magnesium * Proton pump inhibitors and other medicines that alter stomach acidity * Bile acid sequestrants such as cholestyramine * Sucralfate * Certain cholesterol-lowering medicines * Some anticonvulsants * Warfarin and other anticoagulants Calcium and iron supplements are generally separated from levothyroxine by **at least 4 hours** unless otherwise instructed by a healthcare professional.

Yes. 12.5 mcg is a relatively low dose and may be used when initiating treatment, in people who require a small dose adjustment, or in certain patients who need cautious thyroid hormone replacement. The appropriate dose varies from person to person. ### When should I take Levothyroxine 12.5 mcg? It is generally taken once daily on an empty stomach, preferably **30–60 minutes before breakfast**, with water. Follow your doctor's specific instructions. ### Can I take Levothyroxine with food? Food can reduce or change the absorption of levothyroxine. For consistent treatment, it is generally recommended to take it on an empty stomach and maintain the same routine every day. ### Can I take calcium or iron with Levothyroxine? Calcium and iron can reduce levothyroxine absorption. They should generally be taken at least **4 hours apart** from levothyroxine unless your healthcare professional advises otherwise. ### How long does Levothyroxine take to work? Some symptoms may gradually improve over several weeks. Thyroid hormone levels are usually monitored through blood tests, and your doctor may adjust the dose based on the results. ### Can Levothyroxine be taken during pregnancy? Yes. Levothyroxine is commonly used during pregnancy when thyroid hormone replacement is required. Adequate thyroid hormone is important during pregnancy, but the dose should be managed by a healthcare professional. ### What happens if I miss a dose of Levothyroxine?

Your doctor will determine the appropriate testing schedule. TSH is commonly monitored after starting treatment or changing the dose and periodically once the appropriate dose has been established. ### Can Levothyroxine cause palpitations? Palpitations or a rapid heartbeat can occur when the thyroid hormone dose is too high for the individual.
