I have taken Armour thyroid since I was 25, am 63 now. For the past 20+ yrs. the dosage has been 4 grains daily. This whole time, including test results from last month, my Free T3, FreeT4,and TSH are always within the normal lab set range. This is the only medication I am taking. I feel fine but for the past 2 years I'm gaining an average of 2 pounds a month. Right now I weigh almost 140 pounds (5'2"). My eating habits have not changed and I have been excersizing more. The doctor feels it is from the thyroid medication. We have tried cutting the dosage down, but I become very fatigued, my skin cracks from being so dry, and my chlorestrol level becomes elevated. Brings me back to square one......Has anyone ever heard of a person reacting this way to Armour thyroid especially after being on the medication for so long.
When I was put on Armour I gained 15 lbs in 3 weeks. They put me back on Thyrolar and slowly the weight came off. Unfortunately I still don't have good lab #'s so now it's back to Synthroid and Cytomel. I don't know that I'll ever find a good med or good dose.
I started out on Armour and I gained more than 10 pounds in the first 3 weeks. I stopped it, I had never had weight gain, even with the hashi's and nodules, I lost weight. Only the Armour made me gain weight.
I should have added, when I was switched over the Synthroid I lost 9 pounds in 4 days. I don't think I will try Armour again. It made me feel great, but the weight gain freaked me out.
