underactive thyroid
"Levothyroxine - 0.50mg for 1 year. Aged 54. I have had many side effects from this medication: severe fatigue; extreme weight loss; heat intolerance; fever; excessive sweating; depression; headache; insomia; muscle weakness; extreme hairloss; skin rash and decreased bone mineral density.  I have been prescribed with sleeping tablets and Prozac to no avail.  I have also been recently diagnosed with Fibromyalgia. Having done some research, I have found that Levothyroxine makes you deficient in iron; multi vitamins and calcium - hence the hair loss and weak bones. My GP said she's unable to change my medication as this is the only one available. "
