Levothyroxine100mg is no longer working for me ?

Hi, my100mg levothyroxine tablets are no longer working for me.I have been taking these for 2 years with a gradual spiralling weight gain. I am now tipping 12 stone instead of a normal 10 stones. I break out in hot sweats and have severe insomnia.. 6 days ago, I just collapsed and spent the day in bed instead. I have not taken levothyroxine since. Instead I am taking, high dose multi vitamins, sea kelp and selenium, I eat natural porridge for breakfast and high proteins of chicken and beef and green vegetables. I eat cheese in moderation and natural fruit juice but no bread. Am I doing the right things here ? Thank you for your time. ## HI, Margriet! Sorry about the issues that you're having. However, I'm curious as to how old you are? If you've over 35, these same symptoms ...

Levothyroxine and Ringing in the Ears

I was recently diagnosed with Hypothyroidism after having my thyroid tested and my TSH was 5.9. I have been taking Levothyroxine since the end of June. The middle of July I started having non-stop ringing in my ears and still continues. I also have experienced severe hair loss and cannot put weight ON. Is it okay to stop taking Levo to see if the ringing in my ears stop? I really don't want to be on this medication, but don't want to cause additional issues as I'm getting married soon. Appreciate any sound advice. ## I have been on levothyroxin for a good while now.i just had a week away and forgot my pills.BUT I feel good.i don't feel as tired I have less headaches.less noise/ringing ear noises.and basically feel better without my pills I don't think my doc will be ...

Please help. Is the levothyroxine making me crazy?

I was diagnosed with hypothyroid about 7 yrs ago. I was taking 50 mcg of levothyroxine up until now. I am currently 29 weeks pregnant and my new doctor put me on 125 mcg. My doc says i have to be on a higher dose during pregnancy or the baby will be born with birth defects or have learning disabilities. The road has been really rocky. My moods have been up and down, i suffer from severe depression, mood swings, horrible anger, memory loss, bad anxiety attacks and fear of loosing myself. I litterally feel crazy. I asked my doctor and there is nothing she can do except put me on some antidepressant. I dont think i need that and i dont really like takin meds like that. I absolutely think the levothyroxine is making me worse. I feel suicidal and thats not something i want to feel esp. durin...

Levothyroxine and heart rate

I wanted to know if anyone on Levothyroxine has this problem. I've been on 50 mcg of Levothyroxine for about two years (went off it for several months this past year but went back on it). Lately it feels like my heart is beating stronger and sometimes it beats somewhat faster. Taking a hot shower triggers rapid pounding heart beat. These symptoms come and go and seem to be helped if I drink a lot of water. It also seems to help if I get to bed at a decent hour and get enough sleep and eat the right foods and enough of them. The slightest amount of everyday stress can make my heart start beating in the way described. I've been sedentary quite a bit and getting exercise (Walking for 20 minutes) can be a challenge since I lack energy. Also I have been feeling anxiety and depression...

I am on levothyroxine, linzess, omeprazole, ospemifene and (topiramate 2x daily). How am I supposed to space these medications apart so that I receive the full benefit from each one?

Amneal Levothyroxine

I'm changing from Armour Thyroid to generic Levothyroxine. Any feedback as to the quality of the manufacturer, Amneal? I'm a little dizzy, and my eyes hurt and are very dry. ## They are a reputable manufacturer, but Armour Thyroid and Levothyroxine are not exactly the same, though they do treat the same conditions, so it is normal that you may experience some side effects, when you first switch. Other side effects to Levothyroxine may include weight changes, nausea, and loss of facial hair. How are you doing, now? Has there been any change? ## I changed from Amour Thyroid to Nature-Throid. Amour changed the inert ingredients and I became allergic to them. I am now on Nature-Throid and it is excellent. ## I have found that I can only take the Mylan brand for some reason. Pharmacy...

Levothyroxine and Osteoporosis

I had a thyroidectomy in 1988 for a non-toxic goiter and began taking Synthroid and then levothyroxine. In 2018 I had another thyroidectomy because the thyroid gland grew back. I'm now taking 1.50 mcg of the medication. I recently checked the monograph and discovered that this medication can cause osteoporosis. I was diagnosed with this in May of 2018 during a bone scan preceding the thyroid surgery. Has anyone else had a diagnosis of osteoporosis while taking levothyroxine? I'm pretty surprised that I would have this ailment even though I'm 75. I've never been a thin woman which seems to be the person who most often gets osteoporosis. ## No, but I feel so weak my bones, so much pain namb . :( I feel levothyroxine it’s the trigger of all my symptoms. Diagnosed 5 mo...

levotiroxina sodica

I think this is the mexican version of levo throxine 100 mcg. ## I think they also call it that in South America. Maybe if you check the page on Levothyroxine you might be able to find out useful informations. ## I take 75 mcg of levothyroxin daily and was able to get sintrocid/levotiroxina sodica in Mexico. Am I going to be taking the same medication? ## Yes, this is the Spanish name for Levothyroxine, they should be equivalent, as long as the dosage is the same. However, foreign medications are not always FDA approved and regulated, so you do need to be careful as it may not meet U.S. purity and potency standards, which is why I stated 'should be equivalent". There is no way to know more, without more details. Do you have any other information, such as markings on them, or the...

Insurance Covers Medication But Forced to Pay Cash?

Yesterday, I had an appointment with a brand new doctor that is in another state. He wrote me a prescription for a month supply of my medication and after stopping at and calling approximately 35 different pharmacies attempting to get the medication filled, I was given the name of a pharmacy by a very kind gentleman that had experienced the same problem. The medication I take is unfortunately very hard to get a prescription filled for if your doctor is not within your state and I live basically on the border of two other states, MD and PA. I called the pharmacy I was given the name of and indeed they did agree to fill the prescription. I inquired about acceptance of my insurance before going to the pharmacy and they stated that yes they did accept insurance and they would run the medica...

Levothyroxine vs. Levothyroxin

I had thyroid cancer and had a TT in 2017. I've been on Levothyroxine 150mcg for almost a year. The pills have always been light blue colored and round with a stamp of jsp on one side and 520 on the other side of them. I recently switched pharmacy and just opened them to discover the label says Levothyroxin 150 mcg tab Santos. They are blue, oval and say 150 on one side and GG 338 on the other. They look NOTHING alike and are not called the same. There was plenty of room on label, so its not that there wasn't room for the 'e' at the end. Am I taking the same stuff? It's been hell getting my levels right and I have nodules growing again and monitoring my antibodies for the cancer. I cannot afford to be on a lesser effective drug. Are these the same? They sure look tot...
