For Underactive Thyroid "I have been taking Levoxyl for 3 months, and my blood tests have gone down from 110 to 65. It's still not normal, still underactive thyroid. Half my hair has fallen out in the 3-month period. My stomach hurts, and the doctor said no Pepcid or antacids for 4 hours after taking the medication. My joints and muscles hurt all of the time, and I have insomnia. I think I may be adapting to the meds, as I no longer have to spend half the day in the bathroom. Diarrhea has lessened, but stomach cramps persist. I was just told I need to increase the Levoxyl to 0.75 mg. I'm terrified I may end up bald with an ulcer."

For Hashimoto's disease "Taking Levoxyl for about 6 months, and unfortunately not working for me. The stomach pain is unbearable at times and unpredictable. Hair loss, spasms, vivid dreams, headaches, that horrid brain fog. (Hashimoto causes hair loss, including the medication. Make sure your iron levels are optimal.) These are just a few of a long list of side effects. Took Synthroid for about 2 years, and it worked to some degree, but hair loss was a nightmare and the lactose coating was a no for me-continuous digestive issues. Digestive issues with Levoxyl is enough to get me to seek other treatment."

"LOVE this Levoxyl. I am 55 and in menopause. Have had several blood works and told doctors how crappy I felt, no energy, in a fog, hair loss, all the symptoms of menopause and then some. I go to Mexico, tell a doc the SAME symptoms and suggested I take this medicine and I would feel better, get out of the fog and frumpy slump I was feeling, have more energy, AND MAN, after 3 weeks I feel fantastic. I don't even crave sweets or want to eat as much. I have that ZAZAZOO back in me. I feel more alive and sexy. I am single and I don't want to live my life without having FUN. This medication has brought some life back in ME!"

For Hypothyroidism, After Thyroid Removal "I had radioactive iodine (RAI) 29 years ago and have been on Synthroid all that time. The side effects I had got worse as the years went by. I had rapid heartbeat (overmedicated) and just felt awful as the years went. I just switched to Levoxyl 6 weeks ago, and most of the adverse side effects I had on Synthroid have subsided. However, I am listless, loss of hair is bad, terrible brain fog, and just as weak as can be. Increased the dose two weeks ago and still no response. Sorry I cannot rate this a 10 yet. Will stay on it for another 6 weeks and then rerate it. Right now not responding properly."

For Hypothyroidism, After Thyroid Removal "I was doing okay on Levoxyl until my last refill. Finally put it all together tonight and figured it out. Refilled March 3, 2022, and started to feel bad three days later. At first, I was tired, and then cold, hair falling out, my ears are ringing, increase in appetite, aches and pains, constipation, dry mouth, foggy brain, and just getting worse and worse. I do not have a thyroid, so I completely depend on the medication. This happened once before when I was on levothyroxine, and they ended up recalling that med. This is awful. Will call pharmacy tomorrow. Heart rate is in the 50’s, slowing down."

"I have had a complete thyroidectomy after being diagnosed with cancer. Although Levoxyl has fewer side effects than some others, my major complaints are insomnia, fatigue, and hair loss."
