For a year I had all the symptoms of hyperthyroidism, rapid heart beat, muscle weakness, no sleep, bulging eyes, weight loss, etc., but the drug Evista masked the thyroid lab tests. When I ceased taking Evista, a subsequent lab test showed extreme hyperthyroidism. No doctor treating me knew of the connection. After treatment with nuclear medicine, I became hypothyroid and required Levoxyl. Dosage is monitored and has remained at 75 mcg for two years. I am "cured" because my thyoid is now normal, and I have absolutely no side effects from the Levoxyl. I am a 70-year-old woman who hates to take pills, but this is mandatory. I had lost 15 pounds and in two years have gained 5.
