Starting synthroid dose

[Dlonelyguy]

Hi experts,

Finally i got diagnosed with hypothyroidism today with my TSH at 13! Phew! The doctor has prescribed synthroid - 88 mcg. I am having cognitive/memory issues as well. Is the dose right-not too high or too low? Sorry for the naive question but I am a little unsure as my GP appeared to be a little inexperienced. Also how much time does it take for the symptoms to clear up? - I know it will vary from person to person but just need a ball park figure. Looking forward to some expert advice.

Dlonelyguy,

75-100mcg is an appropriate starting dose but it may need adjusting in a few weeks.

For maximum absorption Levothyroxine should be taken with water 1 hour before or 2 hours after food and drink, 2 hours away from other medication and supplements, and 4 hours away from calcium, iron, vitamin D supplements and oestrogen.

It takes 7-10 days for Levothyroxine to be absorbed before it starts working and it will take up to six weeks to feel the full impact of the dose but symptoms may lag a couple of months behind good biochemistry when you are eventually optimally medicated.

You should have a follow up thyroid test 6-8 weeks after starting Levothyroxine. Arrange an early morning and fasting (water only) blood draw when TSH is highest, and take Levothyroxine after your blood draw.

Thanks a ton Clutter ! I am 5'11 and 75 kgs. Just wanted to be doubly sure if 88mcg is too much at 13 TSH. I have heard that you can't go back to a lower dose and hence the question.

Dlonelyguy,

Dose can be increased and decreased anytime as required. Most people will be comfortable after TSH is 1.0 or lower with FT4 in upper range.
