Quick Answer
Yes, you can take thyroid medication at night before bed. Thyroid medication like levothyroxine is typically recommended to be taken first thing in the morning on an empty stomach. However, taking it at night before bed can be equally effective for some people. The most important thing is to be consistent and take it the same way every day.
When is the best time to take thyroid medication?
The recommended time to take thyroid medication is in the morning at least 30-60 minutes before eating breakfast. This allows the medication to be absorbed without interference from food or other medications.
Taking it this way ensures the thyroid medication is absorbed consistently, leading to stable and optimal thyroid hormone levels.
However, some experts argue that taking thyroid medication at night may be equally effective. The critical factor is when you take it relative to food, rather than the time of day. As long as you are consistent.
Taking it in the morning
Taking thyroid medication like levothyroxine first thing in the morning on an empty stomach allows it to be absorbed effectively.
Food and drink can interfere with absorption and cause inconsistent thyroid hormone levels if taken too close to the medication.
That is why it is recommended to wait at least 30-60 minutes after taking levothyroxine before having coffee, juice, milk, calcium supplements or eating breakfast.
Taking it at night
Some studies have found no difference in thyroid hormone levels when levothyroxine was taken at night vs the morning, as long as it was taken correctly.
The proper way to take it at night is at least 2-3 hours after your last meal and at least 4 hours before your next meal.
This ensures there is no food or drink that can interfere with its absorption.
It also allows enough time for the medication to be absorbed before breakfast starts affecting absorption.
Pros and cons of taking thyroid medication at night
Here are some of the key pros and cons of taking levothyroxine and other thyroid medications at night instead of the morning:
Pros
- Don’t have to worry about timing with breakfast

As you can see, taking thyroid medication at night has both advantages and disadvantages. It can be a suitable alternative if taking it in the morning is not working out. But you need to be organized and diligent to take it properly at night.

Tips for taking thyroid medication at night
If you and your doctor decide that taking your thyroid medication like levothyroxine at night may be beneficial for you, here are some tips:
- Take it at least 2-3 hours after your last meal of the day
- Set an alarm to take it at the same time every night

- Keep your medication on your nightstand with a glass of water
- Avoid calcium supplements, iron pills or antacids at night
- Don’t eat anything after taking it except water
- Get blood work done regularly to monitor thyroid levels
- Be aware it may take 12 weeks to see the full effects on thyroid levels
Following these tips will help ensure proper absorption and consistency if taking thyroid hormone replacement at night.
What should you avoid when taking thyroid medication at night?
There are certain foods, drinks and medications you should avoid within 4 hours of taking thyroid medication at night:
- Food of any kind
- Calcium supplements or antacids
- Iron pills or multivitamins with iron
- Fiber supplements like psyllium
- Coffee, tea, milk, or juice
- Soy products
These can all impair the absorption of thyroid medication if taken too closely together.
You also want to avoid inconsistent bedtimes or nighttime dosing. Take the medication at the same time each night to keep thyroid hormone levels steady.
How long before bed should you take thyroid medication?
It’s recommended to take your thyroid medication at least 2-3 hours before going to bed when taking it at night.
This gives enough time for it to be fully absorbed before sleep.
Taking it too close to bedtime can result in poor absorption as your body is less efficient at absorbing medications when lying down.
Some experts advise waiting at least 4 hours before lying down after taking thyroid medication at night.
Give yourself enough time in the evening by taking it after dinner but well before going to sleep. Be consistent with the timing every night.
Can thyroid medication be taken immediately before bed?
It is not advisable to take thyroid medication like levothyroxine right before bedtime. Trying to take it immediately before sleeping doesn’t allow enough time for proper absorption.
Thyroid medication absorption happens best when you are upright, awake and active. Lying down inhibits the absorption process.
Taking levothyroxine too close to bed also increases the risk of choking or aspirating the pill if you fall asleep before swallowing it completely.
For best results, leave a window of at least 2-3 hours after taking your thyroid medication before going to sleep. Set an evening alarm and make taking your pill part of your pre-bedtime routine.
Conclusion
While the standard recommendation is to take thyroid medication first thing in the morning, taking it at night before bed is an equally effective option for some people.
The critical factors are to take it on an empty stomach, at least 2-3 hours after your last meal and 4 hours before eating breakfast. Be consistent with the timing every evening.
People who have trouble with morning absorption or inconsistent schedules may do better taking their thyroid medication like levothyroxine at night. But work closely with your doctor and monitor your thyroid blood work to ensure optimal results.
