Should I Take 'euthyrox' For Hypothyroidism If It Causes Hot Flashes?

I am currently on 50 mcg of Euthyrox.for hypothyroidism.Intially all is well but after 10 days of taking, I feel like warm feeling on face like hot flashes, sometimes for a short while sometimes for a few hours. Also feels slight rapid heart beat but gone in a while. Unable to sleep soundly at times during the nite. I am 52 yrs n started to menopause.
Should I continue with the medication? Dr says should hv no side effect since dosage is low. Am on Conversyl 10 mg n Vascor 10 mg
