I can only take brand name Synthroid. At one time, the generic 'Levothyroxine' was prescribed by my doctor. I started loosing my hair, and spent 3 years going to several dermatologists to avail. It got to the point, my scalp was showing. Than I saw a documentary on TV about the brand name Synthroid, and how some people get affected if they take the generic. One of those side effects, was hair loss. In January, I had problems with my new current pharmacy filling my Synthroid, even though my doctor submitted the request for brand name Synthroid. They kept trying to send me the generic. Finally, they sent me the Synthroid pills. After taking these for 3 months, I'm having hair loss. How can I verify that these pills are brand name, other than just by the label?
