@lilyann I had been taking Synthroid, the brand name, for years till a generic came on the market and my pharmacist switched me to that (as is required by our government run health plan). I had side effects with generic Levothyroxine and asked to go back to Synthroid. I have to pay a bit more, but it was worth the extra cost to me ( about $8 more than my co-pay amount of $3).
