The online pharmacy ECHO sent me the brand TEVA 100mg. I suffered nagging low level headaches, behind the eyes and the back of the neck. My ankles swelled up and I was getting a fluttering in my chest. Aching joints at the fibromyalgia points on the body. Initially I thought it was my supplements Metabiotics liquid B12 etc, I stopped all supplements but this failed to work...well some symptoms went away....the headaches and some fibromyalgia points got slightly better. I called Metabiotics and the woman said it is a natural product and should not cause any adverse effects, she checked all my medications and told me there should not be a reaction. Then she asked me has the brand of any of your medications changed in the last month. YES, I am usually given Northstar or Almus Levothyroxine but I was recently sent TEVA which I have never taken before. I decided to check the list of ingredients and one ingredient stood out which was not in the other 2 brands....MANNITOL! Common Side Effects of Mannitol
are: Headache or dizziness. nausea and vomiting, thirst, dehydration, and frequent urination, racing heartbeat, low blood pressure, rash or hives, blurry vision, altered levels of sodium, potassium, and chloride in the body and acidity in the body; the latter is what probably caused the fibromyalgia symptoms. I informed my GP and was told they could not recommend a different brand due to Covid-19 and possible sourcing problems. I contacted Echo and they added a note to my medication info. this week I received NORTHSTAR Levothyroxine and everything went back to normal after a few days including my mood which I had not really thought about but that could be because I am now back on the B12 supplement. Just as a note the brand TEVA has a history and the UK government suspended their license in 2012, they got it back by reformulating the medication and taking out Lactose.

Lactose and mannitol free levothyroxine brands?
