I am taking a low dose of 50mcg. I took Eltroxin for 5 years and kept feeling uncomfortable, sleep problems, nervousness etc. Since I started Synthroid, 5 years, I have not had any issues.

Started taking this drug 2 years ago but doctor recently increased my dosage from 50 mcg. to 100 mcg. not exactly sure why. For the past 2 or 3 months i've been having bad headaches and stomach cramps and bouts of diarhea and constipation along with drowsiness. Gonna call dr and ask what could be going on. Anyone else been experiencing any side effects from synthroid?

Comment:
This medication is better than taking nothing but,, not totally satisfied with it either. I just feel ok but not great. Does not matter if I'm on the low end or high end of TSH levels either. There is just no happy medium or sweet point either. I have found that I am low on Vit D3 and iron now too. Never had an issue with this before being diagnose with Hypothyrodism. Finding more people that ... Show Full Comment
