Unacceptable side effects of Levothyroxine Posted 2 April 2010 at 22:24 I was described Levothryoxine 2 years ago and my GP has increased it until I am now taking 125mcg. I have never had so many various symptoms in my life - severe weight gain including puffy face and eyes, very itchy dry skin, brittle nails, thinning hair but the major items are the pains in my joints and muscles - especially in my knees and my hands.
