| I am Type 1 and take 150 mcg Levothyroxine. It is usually taken in the morning and on an empty stomach, 30 minutes before eating. It is good to try to take at the same time each day.
Thyroid hormones can affect blood sugar levels. It is suggested to adjust the dose of diabetic medicine once you begin to take levothyroxine. I am on insuline pump and also take Glucophage 2 times a day. I used to take 2X850 mg; when I start to take levothyroxine, the dose of Glucophage was increased to 2X1000 mg.
It is also important to remember that certain medicines may decrease absorption of this drug. Therefore, levothyroxine should be taken 4 hours apart from calcium supplements, iron supplements, aluminum, calcium or magnesium antacids etc. Dietary fiber. soy products, walnuts may decrease absorption of this medication when taken at the same time.
Another important point is that levothyroxine interacts with many drugs (high dose aspirin,antidepresants, etc).
I am sure you may talk all those with your doctors, I wanted to emphasize.  |
