Levothyroxine for Hypothyroidism, After Thyroid Removal "This medication does not work the same as other thyroid medications. I have been on thyroid medication since I was 15. Walmart switched me to this one, and the pharmacist assured me it was exactly the same. I trusted them, and they were wrong. My levels shot up, I started gaining weight (40 lbs), I’m swelling, have brain fog, am irritable, heat and cold intolerant, and I’m so tired during the day but can’t sleep at night. I don’t understand how this can be given to us without them fully explaining the differences in the medications. This could be very dangerous for someone like me as I no longer have a thyroid. My doctor wrote me a new prescription yesterday, and when I got home from getting it filled, I realized they gave me Euthyrox again. I had to go back up to the pharmacy and have them switch it. They apologized for giving me the wrong one and replaced it because my doctor included in the notes to not give me Euthyrox anymore. I can’t wait to start feeling better again."

Levothyroxine for Hypothyroidism, After Thyroid Removal "Horrible medication. I’ve tried taking it several times, but kept having to stop after just a few days. I feel as if not taking anything. Horrendous fatigue, severe brain fog, I’m freezing cold, slow pulse, body aches, puffy, irritated eyes, etc. Look at the horrible reviews! Out of 130 people, it scored an average of 1.6, which is what you’d choose to indicate it’s ineffective, and 93% saying it’s terrible. How is the FDA not reviewing these complaints?"
