ThyroxineAbout this product
What Is Thyronorm 150 mcg
Thyronorm 150 mcg is a synthetic thyroid hormone tablet made by Abbott. Its active ingredient is thyroxine Sodium 150 mcg, a lab-made version of the hormone your thyroid gland produces naturally. It comes in tablet form and is taken once daily. Most patients on this dose have been moved up from a lower starting strength.
What Condition Does It Treat
Thyronorm 150 mcg is used for hypothyroidism, a condition where the thyroid gland does not produce enough thyroxine on its own. Patients often feel tired, gain weight without explanation, feel cold even in warm rooms, and have slow digestion. It is also used after thyroid surgery or radioactive iodine treatment, where natural hormone production has been reduced or stopped. Some patients take it as part of thyroid cancer follow-up therapy.
The goal is to bring thyroid hormone levels back into the normal range.
How It Works
The thyroid gland normally releases thyroxine (T4) into the bloodstream. When the gland cannot do this properly, thyroxine Sodium works as a direct replacement. Once absorbed, the body converts T4 into triiodothyronine (T3), which is the active form that cells actually use. T3 regulates metabolism, body temperature, heart rate, and energy production.
The replacement hormone behaves the same way as the hormone your body would make. TSH levels in the blood are used to confirm whether the dose is correct.
How to Take It
Take Thyronorm 150 mcg once every morning. Take it at least 30 minutes before eating or drinking anything other than water. Same time every day, no skipping.
If you miss a dose, take it as soon as you remember on that same day. If you have already moved on to the next day, skip the missed dose and continue as normal. Do not take two doses on the same day to make up for a missed one.
Side Effects
Side effects with thyroxine are usually linked to the dose being too high rather than a reaction to the drug itself. Mild side effects include:
- Increased heart rate
- Feeling too warm or sweating more than usual
- Mild headache
- Difficulty sleeping
- Loose stools or increased bowel movements
- Feeling restless or anxious
Serious side effects that may need medical attention include:
- Chest pain or irregular heartbeat
- Severe shortness of breath
- Muscle weakness or tremors
- Extreme weight loss in a short period
Chest pain with a fast or uneven heartbeat should not be ignored. Seek emergency care right away if this happens. Talk to your doctor before adjusting your dose based on any symptoms you notice.
Who Should Be Careful
Patients with heart conditions, adrenal gland problems, or diabetes need close monitoring when taking thyroxine. The dose may affect blood sugar control and how certain heart medications work.
Calcium supplements, iron tablets, and antacids can reduce absorption if taken within four hours of your Thyronorm dose. Space these out. Pregnant women should not stop taking it without medical guidance, as thyroid hormone is needed for foetal development.
Storage and Handling
Store Thyronorm 150 mcg at room temperature, away from moisture and direct sunlight. Do not store it in the bathroom. Keep it in the original blister pack until use, as thyroxine tablets can break down when exposed to humidity.
Alternatives Available
If Thyronorm 150 mcg is unavailable, other thyroxine Sodium tablets at the same 150 mcg strength may be substituted under medical guidance. Other strengths in the Thyronorm range include 25 mcg, 50 mcg, 75 mcg, 100 mcg, and 125 mcg. Eltroxin is another brand with the same active ingredient and is used in the same way. Any brand switch should be confirmed with your doctor, as small differences between products can affect TSH readings over time.
This medication is available by prescription and can be ordered online where regulations permit.
