Thyrosit 100mcg Levothyroxine — 500 Tablets
Thyrosit is a brand of levothyroxine sodium, a synthetic form of the thyroid hormone T4. Each bottle contains 500 tablets; each tablet contains 100 mcg (0.1 mg) of levothyroxine sodium.
This page describes what Thyrosit is and how it is presented. It does not assess whether it is suitable for any individual. Levothyroxine dose decisions must be made with a doctor and verified by blood tests at the intervals your doctor recommends — typically TSH and free T4 measured 6 to 8 weeks after any change.
What’s in each tablet
- Active ingredient: Levothyroxine sodium 100 mcg (0.1 mg)
- Brand: Thyrosit
- Bottle: 500 tablets
Usage notes
- Take only as directed by your doctor. Levothyroxine has a narrow therapeutic window: too little leaves hypothyroidism untreated, too much carries cardiac, bone-density, and other risks.
- Dose changes require blood-test monitoring — TSH and free T4 are typically measured 6 to 8 weeks after any change.
- How to take: Levothyroxine is usually taken on an empty stomach (typically 30 to 60 minutes before breakfast, with water only).
- Drug interactions: Allow at least 4 hours between levothyroxine and calcium, iron, antacids, or soy products — these reduce absorption.
- Storage: Keep in a cool, dry place, away from direct sunlight.
- Keep out of reach of children. Overdose in children can be serious.
- If you are pregnant or planning pregnancy, speak to your doctor first. Levothyroxine dose needs typically rise during pregnancy and require monitoring.
- If you have a cardiac condition (especially angina or arrhythmia), levothyroxine starting doses are usually lower and titrated slowly under medical supervision.
