Millions of people in India have hypothyroidism — meaning the thyroid gland doesn’t make enough hormone. It’s treated with levothyroxine (sold as Thyronorm, Eltroxin and other names), taken daily.
But there’s one essential thing about this medicine — if you take it the wrong way, you don’t get its full benefit.
Why take it on an empty stomach?
Levothyroxine should be taken in the morning on an empty stomach, right after waking. Taking it with or after food reduces absorption by 40–80%.
Eat only at least 30–60 minutes after taking the medicine. No tea or coffee either — it can reduce the medicine’s effect.
Keep the medicine away from these
Calcium tablets, iron tablets, antacids (like Gelusil, Digene) — take these at least 4 hours after your thyroid medicine. They all reduce levothyroxine absorption.
Soy products, cabbage and some fibre supplements can also interact with thyroid hormone.
What if you miss a dose one day?
If you miss a day, don’t take a double dose the next day — just continue regularly from the next day. But missing several days in a row makes TSH rise and brings back symptoms like fatigue, weight gain and feeling cold.
That’s why taking the medicine at a fixed time daily is so important. PillMitra reminds you every morning on WhatsApp — helping you build the habit of taking it as soon as you wake.
Get your TSH checked every 6 months
The dose of thyroid medicine changes over time — especially if your weight goes up or down, or during pregnancy. So a TSH test every 6 months is important.
Tell PillMitra the dose your doctor prescribed — it will send reminders accordingly and also remind you when it’s time to refill.
Frequently asked questions
How long after taking thyroid medicine should I wait before eating?+
Take levothyroxine in the morning on an empty stomach and eat or drink nothing for at least 30–60 minutes. No tea or coffee either — it can reduce the medicine’s effect.
Can I take calcium or iron tablets with thyroid medicine?+
No. Calcium, iron and antacids reduce thyroid medicine absorption — take them at least 4 hours apart.
What should I do if I miss a dose of thyroid medicine?+
Don’t take a double dose the next day — just continue at the regular time. Missing several days in a row can raise TSH, so taking it daily matters.
