Can Levothyroxine cause Sweating and Hot Flashes?
I started on Levothryroxine around September of last year after testing borderline hypothyroid and complaining of fatigue. After being on 25 mcg except for 3 days a week where I take 50, it got my TSH back to around 2.5 as I recall. I am having the most awful sweating episodes it is as if I am going through menopause all over again. Has anyone had this experience with Levothyroxine? I take some other meds so it is hard to know if this is the culprit but it is the one I began most recently and seems most likely the cause at least to me. I should probably get tested again but is it possible that even if your TSH is where they want it to be (they tested the free T3, T4 and some other things as well) that this particular medication just doesn't agree with me? Has anyone had levothyroxine cause sweating?

This discussion seems to have resurfaced pertaining to sweating and Levothyroxine. Levothyroxine is a medication used to treat hypothyroidism. In my husband’s case (he had thyroid cancer and his thyroid was removed) it is to replace the function of the thyroid. He has experienced that his levels (TSH, T3, T4) have to be monitored and the dose adjusted from time to time. He does to “run hot” year round and we live in Minnesota! I posted about this early on in the discussion.
My own experience with overheating and thyroid was early 2000’s when I was diagnosed with hyperthyroidism. I was in my early 40’s. I was hot and sweaty most of the time. I was also full of energy, never hungry, never tired but didn’t realize it at the time. I thought I might be starting early menopause. At a routine follow up appointment for something else I mentioned it to my provider. She ordered some tests and diagnosed me with hyperthyroidism. Then she prescribed a medication for it.
My point is that temperature disturbances can be related to thyroid function &/or thyroid medication. My answer to this is to ask your provider. Perhaps some testing is needed or maybe an adjustment in medication dose.

I’m in the process of several tests to find out what the issue is, but I can’t help but believe it’s the levithyroxine. I’m also on a couple other drugs.
I’m in the process of being tested for hypothyroidism. Up till this year my TSH has been normal. Then it was 6 and retested at 4. The endocrinologist was ready to prescribe Levothyroxine, but I wanted one more testing cycle.
My TSH may have risen because I went off a statin. Statins are known to slightly suppress TSH numbers. I was off the statin for 6 months before TSH was tested, enough time to get the statin out of my system. So going off may have caused mine to go up - and I’m hoping it normalizes. Although I don’t think the endocrinologist feels the same.
I also think my iodine was low. I do not salt anything, and table salt is where many of us get our iodine. My blood pressure was high so I lowered salt. Currently my sodium levels are below normal, so I know what I’m doing has made an impact. (Really didn’t seem to help lower BP though). I’m eating Nori seaweed for iodine. So we’ll see.
I am not in favor of getting on the Levothyroxine rollercoaster if my numbers stay low subclinical. Levothyroxine causes vasodilation, one reason you’re feeling hot. I’m on tamoxifen, a med to reduce breast cancer recurrence, and it’s also a vasodilator and causes thermoregulation issues - when I can hot due to environmental causes I can’t cool down for quite a while. I’m also on BP meds which cause some vasodilation. It’s like a triple whammy!
When I take drug info to my doctor, I try to reference the manufacturer’s site, or use drugs.com. When doctor’s act as if I’m using social media or Google to state my case, I point to the references that they themself use.
