What Time Of Day To Take Thyroid Medicine?

I have written about this before yet I still see this question come up often within the Thyroidectomy groups: what is the best time of day to take thyroid medicine ( Levothyroxine (synthroid, Unithroid, others)).



The question is usually answered with a lot of misinformation. People are all over the clock. They don't know why they take it when they do, but they don't have any problems, and they recommend you take it at that time too. This is dangerous advice!

There are several things that can interfere with Levothyroxine absorption and make it less effective: an empty stomach,  calcium, and even walnuts! Many food items, including supplements and antacids, can interfere with the absorption.

The instructions are not hard to find nor follow - the instructions come with the medicine straight from the pharmacy. You can also check the manufacturer's website. Thoroughly read the information from the pharmacy.

1. Take it at the same time every day

2. If you forget a dose, take it as soon as you can

3. Do not eat anything one hour before nor one hour after taking the medicine

4. Do not consume calcium or iron four hours before nor four hours after taking the medicine

5. Foods to avoid include Soybean flour, cottonseed meal, walnuts, dietary fiber, and grapefruit juice eaten 4 hours before or after taking the medication.


PILL MANUFACTURERS

Switching between pill manufacturers can change the results. Therefore, talk to your pharmacist about always getting the same pills. If you switch pharmacies, make sure you are getting the same manufacturer. Sometimes your doctor can help by writing the prescription in such a way that assures a certain manufacturer is always used.



CONCLUSION

Most importantly: don't take medical advice from the internet (including from me). Listen to the professionals: your doctor, pharmacist, and the manufacturer's directions.  Read the material that comes with the medicine and you'll find most of the answers to your questions.
