CompositionEUTHYROX 12.5 TABLET 100 is used to treat hypothyroidism by replacing deficient thyroid hormones in the body. It helps improve metabolism, energy levels, mood, and overall hormonal balance.
Take this tablet exactly as prescribed, usually on an empty stomach. Regular monitoring is essential to maintain correct hormone levels. Inform your doctor about heart conditions or other medications before use.
EUTHYROX 12.5 TABLET 100 is used to treat hypothyroidism (underactive thyroid) by replacing the thyroid hormone that the body lacks. It helps restore normal metabolism, reduce fatigue, support weight management, and improve mood. This tablet is also used to manage goitre, relieve symptoms of thyroid hormone deficiency, and support proper growth and development when taken regularly as advised by a doctor.
Follow these instructions while taking EUTHYROX 12.5 TABLET 100:
Swallow one whole tablet with a full glass of water.
Avoid crushing or chewing the tablet.
Maintain a consistent schedule, taking it at the same time each day.
Consult your doctor before stopping or changing how you consume this medicine.
EUTHYROX 12.5 TABLET 100 is taken orally.
EUTHYROX 12.5 TABLET 100 may cause side effects including headache, weight loss, increased appetite, diarrhoea, excessive sweating, and rapid or irregular heartbeat. Nervousness or heat intolerance may also be experienced in some individuals. If any of these symptoms persist or worsen, consult your healthcare provider.
Most side effects are temporary and generally harmless, which resolve on discontinuing the use of EUTHYROX 12.5 TABLET 100. However, if you experience any serious side effects or worsening of any of the symptoms, please consult your doctor.
Here are some tips to manage common side effects:
Headache: Taking the medication at the same time each day, preferably in the morning, may help reduce headaches.
Diarrhoea: Consider taking the medicine on an empty stomach at least 30 minutes before breakfast to minimise this effect.
EUTHYROX 12.5 TABLET 100 contains levothyroxine (12.5 Mcg), which works on the body as follows:
Hormone Replacement: Levothyroxine is a synthetic version of the naturally occurring thyroid hormone thyroxine (T4), which replaces the missing hormone in people with hypothyroidism.
Conversion to Active Form: After being absorbed into your bloodstream, levothyroxine is converted into triiodothyronine (T3), the active form of thyroid hormone, by your liver and other tissues.
Cellular Regulation: The converted hormone binds to specific receptors in your body's cells, helping to regulate metabolism, growth, and development.
Metabolic Function: By providing an external source of thyroid hormones, levothyroxine helps restore normal metabolic function when your body cannot produce enough on its own.
Caution is advised while taking EUTHYROX 12.5 TABLET 100 if you are pregnant. It is best to consult your doctor before taking this medicine. Your dosage might need adjustment during pregnancy, as thyroid hormone requirements often change during this time.
Exercise caution while taking EUTHYROX 12.5 TABLET 100 if you are breastfeeding. It is best to consult your doctor before taking this medicine. Small amounts of levothyroxine may pass into breast milk, but it is generally not harmful to the baby.
Caution is advised when consuming alcohol while taking EUTHYROX 12.5 TABLET 100. Alcohol might interfere with how your body processes the medicine. Try to limit or avoid alcohol consumption during your treatment.
Exercise caution while taking EUTHYROX 12.5 TABLET 100 if you have liver problems. The liver plays an important role in converting this medicine to its active form. Your doctor may need to monitor your thyroid levels more frequently if you have liver issues.
Caution is advised before using EUTHYROX 12.5 TABLET 100 if you have a history of any kidney problems. It is best to consult your doctor before taking this medicine.
You can generally drive and operate machinery while taking EUTHYROX 12.5 TABLET 100. However, if you experience dizziness or rapid heartbeat as side effects, avoid these activities until you feel better.
Tell your doctor about any allergies you have before starting EUTHYROX 12.5 TABLET 100. If you notice symptoms like rash, itching, or swelling after taking this medicine, seek medical help immediately, as these could indicate an allergic reaction.
Caution is advised while giving EUTHYROX 12.5 TABLET 100 to children. Always consult your doctor before giving this medicine to a child. Children may need different dosages and more frequent monitoring of thyroid levels.
Older patients should take this medication under medical supervision, as they may be more sensitive to its effects. Your doctor might start with a lower dose and gradually increase it. Regular monitoring of thyroid function is especially important for older adults.
EUTHYROX 12.5 TABLET 100 can interact with the following medicines:
Calcium and iron supplements: These minerals, including calcium carbonate and ferrous sulphate, can significantly reduce the absorption of levothyroxine when taken at the same time.
Antidepressants: Medicines like sertraline and fluoxetine may alter the effectiveness of EUTHYROX 12.5 TABLET 100, potentially requiring dosage adjustments.
Blood thinners: Warfarin and heparin may have enhanced effects when taken with EUTHYROX 12.5 TABLET 100, potentially increasing the risk of bleeding.
Diabetes medicines: Metformin and insulin requirements may change when taking EUTHYROX 12.5 TABLET 100, as thyroid hormones affect blood glucose levels.
EUTHYROX 12.5 TABLET 100 may interact with several foods that can reduce its absorption.
Soy products: Soy milk and tofu may interfere with levothyroxine absorption.
High-fibre foods: Whole grains and bran may reduce the effectiveness of EUTHYROX 12.5 TABLET 100.
Walnuts: These nuts may decrease the absorption of the medicine.
