Hi everyone,
I'm on synthroid for hypothyroidism. My doctor told me that if I take it in the morning, not to eat anything for four hours afterwards which means I skip breakfast. I've been following this advice, but now I am wondering if it's too strict? I have heard of others being told they can wait just half an hour.
Thoughts, advice? How long does your doc tell you to wait before eating?

ps she also said I can take it before bed on an empty stomach (ie not eat anything for four hours beforehand) but for various reasons I simply cannot do that in the evening.

    Yep, that's about right. I keep mine right next to my bed. As soon as my alarm goes off, I take it. This is around 5:30am. I usually eat breakfast around 9-9:30ish. You should still definitely eat breakfast. Avoid anything with soy in it for the first half of your day...this will include most processed foods, as they are loaded with soy products. Also avoid raw cruciferous vegetables until about lunchtime. Other than that, there really aren't any other food interactions. But definitely still try to eat breakfast...even if it means you have to get up a little earlier just to take your meds.

    WOW! four hours! I am on Synthroid too, I was told to wait 1/2 hour to eat, but mainly not to have any dairy within the 1/2 hr because that neutralized the drug. I also have another friend on Synthorid also and she was told to wait an hour, I don't know if the wait period changes with the amount of the dosage. Maybe contact your pharmacist they would know about wait time and food reaction, maybe more than your Dr. would.

    I have been taking Synthroid for years and have ALWAYS only waited 30 minutes before I eat. My levels have stayed within the normal range on my dosage, so a half hour must be sufficient. I too take mine in the morning, and sometimes 30 minutes is even too long to have to wait to eat lol! I could never wait several hours.

    I have been on synthroid since 2005, when i was diagnosed with thyroid Cancer. I was told to wait 3 hours to eat or even drink coffee but for me that just didn't work. I usually take my pill and have my coffee 20 min later, I wait about 1.5 to 2 hours and then I eat breakfast. I can't go all morning with no breakfast. I was told not to take mine at night. My point is, I feel fine with taking it the way I am and I get tested every 6 months and my levels are always normal.
    Good luck to you.

    I've been on Synthroid for years, and I've always taken it first thing in the morning when I wake up and eat breakfast 30 - 45 minutes after taking it. This has never been a problem, and my thyroid bloodwork has measured in the normal range since starting this routine. I have been told that calcium can interfere with the absorption of the drug, so do make sure you wait AT LEAST 1/2 hour before drinking milk or ingesting anything high in calcium.

    Hi, I'm on Synthroid as well and my instructions are not that strict and my thyroid levels are fine. I take my Synthroid first thing in the morning when I wake up. Then I can eat after 1 hour. Sometimes I forget and eat and it's ok. Just try not to do it everyday. It is best to take it in the morning because once you eat something and forget to take the pill, you have to wait 2 hours after you eat then take the pill and have to wait another hour before you can eat again. So it does get a little confusing. That's why I take mine first thing in the morning with my daily baby aspirin so that I never forget. Hope this was helpful for you. Good luck!

    I take Synthroid for years and was told to wait 30 min before eating, never was told to avoid any kind of food and i don't and my levels are good. My husband takes it too and he takes it with food though he should wait 30 minutes, but his blood work comes back good too.

    It says a half hour on my bottle. Sometimes I wait, sometimes I don't. It doesn't seem to affect anything for me.

    I'm on Levoxyl for hypothyroidism, same basic idea. I was told to take first thing in the morning and to wait a half hour to an hour to eat. I confirmed this with doctor and pharmacist. I typically wait several hours just because I'm never hungry in the mornings, but I wouldn't sweat it if it was only an hour.

    Thanks so much for all your help guys. I think I'll speak to the pharmacist and doctor again. I also checked on synthroid's website and even there it says 30 minutes to one hour is enough, as long as it's not heavy in calcium or iron. And I will avoid those other foods for the specified times as someone mentioned so kindly. Yay! Looking forward to breakfast now!

    I've been on thyroxine since 23 months old and no doctor has ever told me not to take it with food and I'm now 42!

    In fact my mum always used to give me it with breakfast., usually crushed with weetabix to get them down me when I was little. so I've always taken them WITH my breakfast.

    Recently after hearing about this I switched to night time, my GP hadn't heard of this and didn't think it would make any difference as long as I took them?

    Well even the synthroid website talks about avoiding taking it with food or right after eating, or eating afterwards for a while..

    The four hour window after taking your thyroid medication is for foods high in calcium or calcium supplements, as well as foods very high in fiber. Calcium and fiber both block the absorption of the thyroid meds. Otherwise, just wait your thirty minutes to an hour. I found out the hard way that the calcium and fiber render the meds ineffective and don't recommend messing with it.

    My daughter is on Synthroid. Her instructions are to take it with a full cup of water 30 minutes before breakfast.

    I'm also on Synthroid and take it in bed when my husband leaves for work, I get up half our later and get ready and eat breakfast then work out. My issue is I can't lose any weight, my levels are fine. I've been documenting everything I eat and keep within my 1200 calories and work out every day and lost 3 lbs and gained 1 back in two months. What am I doing wrong?

    Yeah, I couldn't eat anything for about a half hour after I took mine. It made me really sick.
    I have eaten, then taken it. I got a little sick, but I'm not sure if that was because of the pill or not.

    My mom takes hers at the end of the day, though it's preferred that you take it in the mornings on and empty stomach. Just find what works for you :)
    You may not have to weight a few hours, just a little while.

    I don't know your stats, but you maybe eating too little. That could possibly be the reason.

    I have been on synthroid for about 2 years and I take it as soon as I get up. I try to wait an hour before I have a cup of coffee. I have never heard of the 4 hour wait period. I don't think I could wait that long, without my cup of java!!!

    I am in the exact same situation, can't lose weight to save my life but the doctor says he can't give a higher dose or it will affect my bones. I also write down everything I eat, 1200 calories, and walk 3 to 5 miles every day. The kicker is I am 6 lbs overweight, not just those 'last' 10 lbs. Also take Met for in for pre-diabetes. It's really got me down. Any advice?

    I meant 60 lbs overweight, not 6 lbs.
