I am 36 years old and since I started on synthroid I have been having hot flashes. I do not think I am going into menapause as my family members didn't until they were in their fifties. Could this be a side effect?
Are hot flashes a side effect of synthroid?

I'm on Synthroid and don't have that problem from that but I heard that having Rai treatment (Radioactiave iodine) can bring on menopause. I just started hot flashes since then.
Buy yourself a hand held fan for when it happens, that's what I did. Helps alot!

I had "hot flash" type symptoms when my doctor increased my dosage. My previous dose.. I was cold, my hands/feet/ butt were always real cold.. dangerously cold in winter. When I started heating up I didn't know how to cool down.. I was never hot before. Still having over heating problems in full sun, and learning how to stay hydrated in summer. The hot flashes did ease. It takes your body months to adjust to new meds or increases. If it continues to be a problem after a month or better talk to your doctor about rechecking. It's better to have your t3/t4 and tsh tested. Hope you get to feeling better.

It can be a side effect, but it can also be an effect of hyperthyroid. When did you have your TSH checked last?

I KNOW that Synthroid is causing my Hot Flashes and am now curious what else it is causing. I quit taking Synthroid, Zoloft, and Estrogen because I was tired of the constant HOT FLASH I had that lasted about 12 years.. I went to a Naturopath a couple of months later and started taking other types of thyroid meds such as WP Thyroid and a compound formula. The Hot flashes went away for the 7 mos I was on the new meds. However, my insurance would not cover any of this experience or the meds so I went back to my normal doctor and he re-established my Synthroid meds. The HOT FLASH was back within 3 days. I consider it a HOT FLASH with an attitude as I am frustrated and aggravated and sweating so badly again. It makes me grouchy and I never feel fresh. I am scheduled to see an Endocrinologist who can perhaps help me find a med that is covered by my insurance but he will not take me for another month so I will have to suffer through it.
