I've taken synthroid and now levothyroxine (generic synthroid) since I was 12 years old. I get my levels checked (blood work) every six months. I've never experienced many problems, and I call my doctor if I feel symptomatic no matter how long it's been between tests. My current dose is 100 mcg and I've been at this level for about 15 years. I have no problems with my hair.

I hope everything goes well with your visit to the endocronologist. Discuss the differences in medications with your doctor at that visit.
