Euthyrox 112?

“Euthyrox 112” usually refers to Euthyrox tablets 112 micrograms (mcg) of levothyroxine (synthetic thyroid hormone).

What would you like to know—how to take it, whether it’s right for your thyroid level, side effects, or something else?

In the meantime, here are the most important basics:

- What it’s for: Hypothyroidism (low thyroid), sometimes after thyroid surgery, and in certain goiter/thyroid hormone–suppression situations.
- How it’s usually taken:
- Take once daily, preferably in the morning on an empty stomach with water.
- Wait 30–60 minutes before eating.
- Keep spacing from interacting products (below).
- Avoid/space from interactions (typically 4 hours):
- Iron and calcium supplements
- Antacids containing aluminum/magnesium
- Sucralfate
- Some cholesterol binders (e.g., cholestyramine/colestipol)
- Monitoring: Dose is adjusted based on TSH (and sometimes free T4). Don’t change dose without your clinician.
- Possible side effects if dose is too high (too much thyroid hormone): palpitations, anxiety, tremor, sweating, insomnia, diarrhea, weight loss, headache.

Quick safety note: If you tell me your age, pregnancy status (if relevant), and your most recent TSH/free T4 results, I can help interpret what “112 mcg” might mean and what to ask your doctor.
