I have been on Levoxyl for years. Have experienced all the side affects this medication has and then some more! My hair loss and thinning, depression, bone aches, headaches, fatigue, and much more...finally I asked the doctor is there was anything else out there in the market which had less side effects....there is a natural product which has been in the market for many years called Armour Thyroid (*******). All I know is that if I continued to take Levoxyl, I will most likely end up in bed for life...I am only 43 yrs old and would like to have at least "normal" energy for my age. There is NO reason I should feel a lot older and I know for a fact it is the medication. I have only been taking Armour Thyroid for just a few days but will report my well being in about the next 30 days. Since I was on 100mg of Levoxyl a day, am taking two grains of 30 mg a day for a total of 60 mg of Armour a day. In about 25 days I go for blood work to check levels, so far I experience a bit of nausea right after I take the "new" medication but it does not last all day. Hopefully, this new med will give me my LIFE back! Thanks for reading.
