Hi,
Though
depression is not a side effect seen with
levothyroxine, but mood swings, (particularly
nervousness and irritability) is a well known side effect of levothyroxine. Similarly, frequent intensification of heart beat as well as loss weight can be due to over dose of Levothyroxine. However, hair loss generally is not a sign of levothyroxine hyper dose, rather it may be a feature of under dose of levothyroxine.
Similarly all other symptoms like being easily upset, irritability, being sad, getting emotional, crying uncontrollably point towards mixed symptoms of anxiety and depression. Therefore, in my opinion, you should go for your
thyroid profile and readjust your doses of levothyroxine, if required. If still the symptoms persist, you are advised to take anxiolytic and / or anti-depressive drugs under guidance of a
psychiatrist.
Take care. Hope I have answered your question. Let me know if I can assist you further.
