Q. How long will it take for the palpitations to go away after taking Levothyroxine?
Hello doctor,
I was diagnosed with hypothyroidism two months back and started on Armour 15 mg. Four weeks later, upon rechecking, my TSH dropped four numbers which were good but I had some palpitations for a short time each day. I just switched to Levothyroxine 50 mg and the palpitations are maybe one hour a day. Any suggestions or is it just going to take more time to adjust to a thyroid hormone?
Hello,
Welcome to icliniq.com.
Have you checked your heart rate during the episodes of palpitations? Nonetheless, the palpitations will get better when you take Levothyroxine dose gradually. So no need to worry about it. Just continue taking the thyroid medicine and your symptoms will improve with time.
Hello doctor,
The heart rate seems to be fine as I had my husband check my pulse and it is normal. I was actually thinking of taking half of the Levothyroxine 50 because it has a score mark down the middle just to ease into the medicine at first. In any case glad you think that there are no worries.

Yes, you can do that if the palpitations bother you a lot. Take 25 mcg this week and 50 mcg from next week. So, if your heart rate is fine then it is not an issue to worry anyway. Try to find a way that suits you since both are equally acceptable methods taking 50 mcg right away or easing gradually towards 50 mcg.
I hope this helped you. Thank you.
Hello doctor,
I just wanted to say that I am still on the 25 mcg Levocetirizine as there are still occasional times of palpitations after 2 weeks. I really would like to go even slower and take the 25 mcg. Would that be okay to do?
Hello,

Yes you can do that break it into 12.5 mcg once daily and ease into it. However please recheck your thyroid function test again. You can also have an ECG (electrocardiogram) done or a 24 hour Holter monitoring for your palpitations, would be better to know that it is normal as well.
Hope you feel better soon.
Hello doctor,
I was wondering if you have heard of bowel movements changing some when starting on thyroid hormone. I am adjusting to the Levothyroxine but I noticed slightly thinner bowel movements at times. No other bathroom issue or pain was involved. Should I try a fiber supplement?
Hello,
Welcome back to icliniq.com
Yes, it can happen due to it. Thyroid hormone fluctuations alter bowel movements in some. You can try a fiber supplement if you feel the need occasionally.
Hope you feel better soon.
