Synthroid (thyroxine): You should wait about an hour after you take your synthroid (thyroxine) or it won't be properly absorbed. You may be better off taking it at bed-time - about an hour after a snack. Your food and drink list sounds just fine. ...Read more

I have hypothyroidism and take thyroxine , is it ok for me to eat cruciferous vegetables and soya products?

I have hypothyroidism  and take thyroxine , is it ok for me to eat  cruciferous vegetables  and soya products?

Yes, however...: Eating large amounts of cruciferous vegetables & soy can suppress thyroid function, but it is not clear how much and moderate consumption, esp. If these are cooked, should not have much of an effect. If you eat very large amounts of these then monitor levels of thyroid hormone to see if you need to take more thyroxine.

I know that Synthroid (thyroxine) is used for hypothyroidism but can it be used to increase appetite in people who eat too little?

No: It should not be used as an appetite stimulant. It will lead to more side effects, and actually suppress your own body hormone, which you may have enough. Extra thyroid hormone will increase your metabolism, your heart rate (leading to possible arrhythmias) and weight loss, diarrhea. Other medications are available as appetite stimulants. ...Read more

Can i take Synthroid (thyroxine) first thing in morning, wait 30 min, take zantac, wait 30 min, eat then pray for no morning sickness? Anyone has a better timing?

Yes: That timing is appropriate for the medications. The other otc medications that can be used for morning sickness in pregnancy are benadryl, (diphenhydramine) doxylamine, and vit b6. Your OB doctor would also be able to offer more suggestions, and you should discuss this with them. ...Read more

Will I be able to eat foods with added calcium, iron and magnesium if I'm on synthroid (thyroxine)?

Food and thyroid...: You can eat any kind of food if taking Synthroid (thyroxine) as long as you take this tablet away from all food and all medications. I highly recommend for it to be taken in the middle of the night so you are sure nothing interferes with its absoprtion. Once absobed - typically in one hour - then any food will not affect this medication. ...Read more

I've been on Synthroid (thyroxine) 25 mcg for 1 month for hypothyroidism & the last 2 weeks my energy level has dropped. I don't even want to eat. Is that normal?

Wrong medication?: it could be your dose is too low or you are on the wrong medication for your thyroid. Some people need Armour Thyroid instead of synthroid (thyroxine). Read: DrFairchild.org/endo/thyroid.htm ...Read more

I have hypothyroism. I take 50mcg thyroxine and 20mcg of tertroxine daily. I exercise intensly 3xweek and eat 1200cal/day and no weight loss help!

I have hypothyroism. I take 50mcg thyroxine and 20mcg of tertroxine daily. I exercise intensly 3xweek and eat 1200cal/day and no weight loss help!

Math does not add up: From your question, the math does not add up if you are taking 50 microgrm of thyroxin and your thyroid function like tsh, t3, (liothyronine) T4 are normal and you are on 1200 calories daily diet and you exercise intensely 3 times a week and still do not loose weight. I will recommend you see your doctor and/or nutritionist as to what you are doing is right or wrong. ...Read more
