It can take a while to find the right dose but you will get there, you just have to take it slowly and be patient. I had RAI years ago and apart from the occasional change in dose I've been absolutely fine, best decision I made 😊
I hope you feel better soon.
Welcome to the forum, Cali29.
Ask your GP to do a repeat thyroid test 6-8 weeks after you increase dose to 50mcg as dose may need adjusting. Arrange the blood draw early in the morning when TSH is highest and fast (water only) as TSH drops after eating and drinking. Take Levothyroxine after your blood draw.
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, magnesium 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. Symptoms may lag behind good biochemistry by several months.
