I set alarms for everything including when its time to take my medicine and I have a medicine app that you can check off in your phone that you took your medicine ,if you dont it'll tell you you missed a dose and show you which meds you didnt mark, I also invested in a 30 day mediplanner as I have a short term memory impairment
I wait 4 hours because that’s how long it’s supposed to take for the stomach to empty. I understand that this med needs to be taken in empty stomach with plenty of water. Hope this helps!
1 hour
I take my supplements, HRT, and other meds at night shortly before going to sleep. Two of the meds are to be taken only at night. Trazodone and cyclobenzaprine (Flexeril). I want to try taking my thyroid meds at night. So how far apart should I take the thyroid meds and the other meds taken at night only? I could take the supplements earlier in the day... but not the two I mentioned above. I also always eat a "midnight snack", and am a total night owl, usually falling asleep around 3:30am.
60 mins.
wait 1 hour before I take my thyroid
The important thing is to take Synthroid at the same time, every day, and stick to having an empty stomach surrounding that time. The argument of absorption is a mute point when your not looking at your lab levels. Dosing can be adjusted to get your levels balance. We're talking about mcg of meds here... Not mg. Tiny little tweeks with fractions of mg of medicine. While research may show that you're getting better absorption at night vs morning, so what? If your levels are in harmony at a specific dosage at that time of day, then THAT is the biggest hurdle cleared right there. Stay consistent in routine once you're balance and that is a winner!!
There is always someone who is rude and knows-it-all on all these sites. Please always consult with your doctor and then only do research on legitimate sites when looking for information. Not 2 people are exactly alike and medications effect people differently. That is why people sometimes ask for a second opinion when they do find out there is something wrong , because they want to make sure that its true and reliable. I honestly do think that these sites are valuable but please never just take the opinion of someone who is not licensed nor a professional.
Hi Medical Mama: Interesting name! Somewhat of an "oxymoron" in relation to your comment to this question!
Read the literature. No one here claims to be doctors. This is a forum where we compare experiences and knowledge through person things we have gone through and things we have personally researched. Why are you here if you are only here criticizing the comment we give to inquiring minds? I did repeat what I was told by my doctor. Why in the world do you have a problem with my answer? Who died and made you my judge? Sheesh!
So, "Medical Mama", please tell us why you are really here??? /
Ahhh yes, I just went to your profile, that speaks volumes. Welcome, newbie!
I have directed people on this site to discuss this with their doctor, and I have also recommended to them to read the information provided by drugs.com on this site to find their answers??? What's the problem, according to Medical Mama with this site???
Yep new to this site... but not new to the Medical Field. I am glad I dont take your remarks seriously. I may end up with not only a ruined Thyroid, but also with mental problems. Thank you for your less that engaing conversation. It always means so much to me, something I could possibly never live without!! Now I must go sit in a dark corner wondering where I went wrong all my life. (Seriously) haha
And as if I was speaking to you, which after your comment I am not sure many people ever speak directly to you. I was looking up something and thought I would read this. I do know that I wasnt trying to be rude to you in general but maybe its time you got yourself that bipolar medication you have needed. You have a great night trolling around on the internet.
I admit I was irritated by your comment about people who answer on this site, so I apologize for that. It is known that this is not a site where doctors are here to answer medical questions. I agree that it is wise to go to a doctor for a problem, and even go for a second opinion when necessary. Most people who come here or join this site are here to share information which they have gained, either through personal experiences, or information learned through personal research, then referring others to same information. I guess I felt as though it was a personal attack on well-meaning people that I have come to know here through our interactions for the last couple of years. This site is not full of "rude and know-it-all people".
It is made up primarily of experienced, caring people who want to share what they have been through and what medications or treatments they went through, and suggestions to help others who come here worried about what they might be encountering ahead in a similar situation. Most of the comments direct the person to seek medical advice from a professional, along with their conversations here. You will begin to see that as you continue to share in these discussions.
Notice this comment I made here on Aug. 16, 2017, for example:
~~~" G Mc 16 Aug 2017:
James, you need to go to your doctor to get the answers if that is the case. This is not a place for professional advice, although there are many knowledgeable people here, nurses and pharmacists, active and retired, also people who share their own personal experiences with medical situations and medications to treat them. But this is not a forum with professionals to answer medical questions."~~~
James had made the comment that he "wanted a doctor to answer him".
I do apologize for the misunderstanding. It was someones post at the top that kind of made me think of why someone would act so offended if other people disagreed with them. I never made it to your post to be quite honest. Anywho... life goes on. I beg of people to always consult the professionals even in my job. Everyday I see patients with Cancer, Heart issues, breathing problems and they ask all the wrong people questions and when there Doctor is in front of them, then they dont peep a word. (Not sure why that happens, but then that is usually when I say for example: Mrs Smith, you wanted to ask the Doctor a question earlier, do you remember what it was?" They have to advocate for themselves and if they cant, they need a close friend or family member to do so. I hope you all have a good night and lets just all get along :)
Hi Medical Mama: Yes, let's! Lol. Those people were lucky to have you there to step in. Some people just seem to have a hard time communicating, or, as you said, asking the wrong person for advice. When I would take Mom to the doctor in her later years, I was amazed at how she would get all dressed up in her finest clothes, just "glow" when the doctor and staff would all tell her how nice she looked, and she would never get around to telingl the doctor what her symptoms were and why she had come in for an appointment! So I would basically do what you just said here. I would help the communication process along so that Mom could get the help she needed. I appreciated your last comment which made a lot of sense!
I want a MD to answer my question
James, you need to go to your doctor to get the answers if that is the case.

You can also go to the top of the page here at drugs.com, type in Synthroid, and search the information for an answer.
This question is for G Mc. I have been reading how beneficial it is to take b.p. pill at bedtime. If I were to switch my synthroid to night time, when would I take the b.p. pill? Just wondering... thanks for any advice you can pass along.
Hi Joyce:
It would be beneficial to wait at least an hour after eating or drinking anything (other than water) before taking your Synthroid at bedtime.
I take "Nature's Thyroid", how long before I can eat after taking?
Hi 1Singer:
My doctor told me to wait at least an hour to eat after taking my morning dose of Nature-Throid. My thyroid levels had gotten way off, but instead of changing my dosage, she told me to take my Nature-Throid first thing in the morning and not to eat or drink anything for an hour. I did this, and my thyroid levels returned to normal!
@1singer: To clarify, I was taking my Nature-Throid along with other meds or supplements sometimes or probiotics capsules, sometimes eating right before or after taking my Nature-Throid. Once I started taking my morning dose of Nature-Throid all by itself without food or vitamins or supplements or any other medications (on the advice of my doctor), my thyroid levels came back in to normal ranges. So it is very important to take it by itself. Avoid eating or drinking at least one hour before or after taking it. Let me know how it goes for you!
I have been taking Synthroid for 13 years. I have always taken mine in the morning when I wake along with all my other meds. Never really thought much about it. I always wait at least an hour before I eat. Only because I am a coffee drinker and it usually takes me an hour to drink my coffee, catch up on Facebook and check my email. LOL My levels have always tested fine but my energy levels are not up to par and I find that it is very hard to lose weight. I have been reading the studies that have been done on taking levothyroxine at night and how the absorbsion of it was better for some people. For people that has other meds to take it may be a better option to take levothyroxine at night. I am going to give it try and see if it makes a difference.
Me too, after reading all comments on this support group, I believe no one can help like another person with the same complaints/illness, I also have to take many other meds including warfarin, around 16 a day and all at different times, eg morning, afternoon, teatime, & evening. Its a nuisance, but that's all it is. Nice being here with all of you and reading the comments, GPs do not have the time to review my meds, but I read about everything to do with my meds, & health conditions, & if I didn't, I believe I wouldn't be around today but that's my opinion. Thank you friends
Coffee interferes which Synthroid's absorption. You must wait 30 mins to an hour, same as food.
Have you tried taking it alone and not with your other meds. I found that some meds may actually interfere with its absorption.
Try waiting an hour or so after to take the rest of you Meds including vitamins. Synthroid is a very narcissistic drug.
Char, all of the literature says to take synthroid or L-thyroxine separate from all other meds as well, because there are different meds that can reduce its effectiveness (I.e. calcium, aluminum in antacid products, iron in multivitamins, etc,). I wouldn’t recommend taking it at the same time as all your other meds.
I started having to take levothyroxine about a year and a half ago. I read so many conflicting arguments about when the best time was to take the medicine. As is reflected in this forum, some people swear by morning and others by bedtime. About the only thing that everyone seems to agree on is that it's most effective on an empty stomach.
So I came up with the perfect solution for myself. I set my alarm every night for 4 a.m., wake up and take my levo, and then go right back to sleep until it's time to get up for the day. I never have to worry about what or how soon I ate before or what or how soon I will eat afterwards. And I'm consistent from day to day in when I take it. Problem solved :-)
I will put it next to my bed though because I usually awaken around 430 to 5. Don't know why I never thought of that.
How long do you have to wait to take your thyroid medicine after you eat
I've been taking L-Thyroxine (Synthroid) for about 20 years. I'm pretty sure your safe if you wait 30 minutes to an hour before a meal and 4 hours after.
After a thyroidectomy in 2014 due to thyroid cancer, my Endo at MD Anderson Cancer
Center advised waiting 30 minutes to 1 hr. Since I work, I usually wait 30 minutes. I have had no issues. I was instructed to wait 1 hr - 2 hrs before taking additional medications.
My endocronoligist is a world renowned dr, he runs a metabolic clinic for a top hospital (local). He has done his own studies with Thyroid Meds and has recommend night time- unless it keeps you up (sometimes a side effect if you start to border on hyper) I too have little kids and have a hard time getting my meds on a strict schedule- just make sure you follow the main concerns : empty stomach, no calcium within 3-5 hours and be careful taking it with other meds or vitamins.
I too read that report. My Nurse Practitioner said that it has been discovered the results depends on when during the day the blood is drawn. She did an afternoon draw and the level of TSH was lower than the morning draw. Maybe it's not taking the medication at night that made the difference.
I'm so glad I've read this comment, as I take(adcal) twice a day for osteoporosis, then a different one on a Friday, it's to protect the bones from any further damage, they also have to be taken before and after food. At least an hour both ways, looks like I'll need to take it at night, or during the night, like someone suggested. How long after a snack at night would it be most effective, anyone help? I don't sleep well anyway, so I can do that. Is it just water we take it with? Thankyou in advance. Jean in November 2016
I take it in the middle of the night with a good size glass of water. Since I get up to urinate. Make sure you take your calcium 4 hours later.
I'm ready to start back taking levothyroxine again. I never saw any good results taking it in the morning. Plus I have other medicine to take. I will start trying taking levothyroxine at night. Hopefully I get great results like everyone else I've read about. It's worth a try.
You might want to take synthroid and not the generic. My body cannot process the generic. Tell your dr and pharmacist you would like to try synthroid, see if that helps
I was on levo and had issues so I switched to synthroid generic. I finally settled on the non generic synthroid. I take it in the morning but I am considering nightime dose.
I have been taking synthroid for almost 5 years, as a result of parathyroid and thyroid surgery (actually 2 surgeries) at MD Anderson Hospital. My doctor is a world renown endocrinologist/surgeon, and she told me it's best absorbed first thing in morning, and if possible the same time frame every morning. She said if taken at night, it can cause sleep disruption in some people. Just my two cents in this conversation
