My husband was just switched from 175 to 200 mcg of Synthroid. Started taking new dose on Saturday and that night upon getting up during the night experienced some dizziness. Happened again on Sunday night. Goes away but wonder if it is caused by the increased dosage. His numbers were Free 1.4 and TSH 4.94. Has anyone else experienced this? He also takes 40 mg of Lasix 2x per day.
I'm on 175 synthroid and experience vertigo often. 4 endo's later and research all say it's not linked. I never had these symptoms before the cancer so i would bet they are! Hopefully someone will link it soon. Get your levels checked is all I can suggest. Good Luck.
