I have thyroxine intolerance?it works,tsh-3.0,but lot of heat,diarrohea etc.may be allergy. need opinion on tirosint.pls help.,any other med i can try

Thyroid treatment: Tirosint is the same levothyroxine as the others, but they advertise no "dyes, coloring, sugars, etc". It is fine to use, although expensive. It would be very unusual to have a reaction to such low levels of these ingredients in a pill. Have you tried other levothyroxine brands, eg Synthroid? Have you been worked up for other causes? Menopausal? Colonoscopy?

Not allergy: Your symptoms do not sound like an allergy to your thyroid medication. Such allergies are extremely rare. Tirosint is a different brand of levothyroxine, that may be absorbed into your system better, but likely will not change your symptoms. I suspect your symptoms are not related to your thyroid or thyroid level.
