I've been getting pneumonia a lot (4 times in a year) probably because I've been taking too much Synthroid (.2mg). My recent CBC shows that my white blood count and TSH are very low. I've been having anxiety for years as well. My doctor has asked me to take 1/2 of the .2mg (.1mg). Will I have side effects from lowering the dosage like weight gain, hair loss, skin rashes). These are the symptoms that I had BEFORE taking synthroid years ago. Will I return to Hypothyroidism?
