"Thyroidectomy after cancer diagnosis, and so far I've had not had great luck with Synthroid. Currently, I'm on 112 mcg, and it makes me feel like I have an itchy sunburn. The weight gain is insane, I feel waterlogged in my legs most of the time and have too many mental glitches. I dislike this drug, it has too many fillers that cause other issues. If you have known allergies, avoid Synthroid until they can create an allergy-free version."

"I was born with a thyroid condition. I am a 23-year-old female. I did the other brand for a while, and it made me tired, sad, and just made me feel hopeless. I am on Synthroid 88 mcg, and although I sometimes feel sad, my weight is maintained, I'm able to work, and play with my 1-year-old daughter, who, thank God, is healthy. Finding the right dosage is so important and is trial and error. If everything is good and you only have one symptom like sadness... get a hobby, again a close friend is so important and always take your pill!"

"After the birth of my twins 32 years ago, I was diagnosed with postpartum hypothyroidism. Started on 88 mcg, and with monthly labs, I found myself within a year at 200 mcg. My grandmother had lupus, and looking back, I think I had some sort of an autoimmune disorder since childhood. Two of my children also have autoimmune disorders, one with Hashimoto's and the other with psoriatic rheumatoid arthritis, and they both have PCOS and the anxiety disorders that go along with this lovely disease. Originally, I was given levothyroxine, but my levels were just not normal, so I was given Synthroid, and it had to be dispensed as written by the pharmacy. I still have symptoms that sometimes feel debilitating. I really feel that Synthroid has obviously helped me, but 32 years on this and still symptomatic and deficient in vitamins, I think it's time that an endocrinologist would allow me to become one of their patients! Autoimmune disorders are no fun!"

"I’ve been on this medication since I was 7, and I am now 32. I never had any issues that I can relate back to Synthroid. But I’m curious if my anxiety and panic disorder are related to this, because I have had it since around the same time I started this med and suffered my whole life. I also recently started having chronic dizziness that is pretty much 24/7 for the last 5 years. It’s probably not related, but I’m curious if anyone else feels the same."

"I have been taking Synthroid for almost two years. My doctor told me that I might not be able to conceive, but I am 15 weeks pregnant. My current doctor told me to take this medicine religiously because this is keeping me pregnant."

"I have been taking this for 6 months now. Before these medicines, I had problems gaining weight. Now that I am on this medicine, I can't stop eating. I have gained 20 lbs. When I stop taking these medicines, I am not hungry all the time. I also have high blood pressure. Not sure if the combination of the medicines has anything to do with the weight gain."

"I have been taking random dosages of levothyroxine for 1 year now, and my endocrinologist and I still haven’t found my perfect dose. I switched over to Synthroid at 125 MCG, and I’ve been on it for about 2 weeks now. I know it takes about 4-6 weeks to hit its peak. But I am just so impatient and tired of it not being my proper dose. I’m 27 years old, and my left eyebrow hairs started to turn white, and my bottom lashes are all white, and now my top lashes are starting to turn white too. It’s very concerning. I was told it’s from my autoimmune disorder. Is anyone else going through this?"

"OK, I'm still on Synthroid, and my doctor will not listen to me. He told me to see an OB/GYN, and they made me an appointment, but I have to wait another two weeks, and my menstruation has gone crazy. I've been bleeding since April 15. I stopped for 2 days, and it started again. All my tests say I'm normal. I went to the ER, and they told me everything was fine! I'm so frustrated with this. No one will listen to me!! It takes 4-6 weeks to kick in. I started this medicine in November, I've had my dosage changed 3 times. This last time, I went from .75 to .88, and exactly 6 weeks and one day my menstruation started early. I thought that was just a slight bump, but now it's out of control! I know my own body, I know it's this medicine. I'm sensitive to medications."

"I've been on both, and yes, you have to see a doctor who specializes in this disorder. You also have to take it one hour before you eat both Levo and Synthroid because I feel different. I've done it taking after I ate, and it didn't work, and then I followed the doctor's orders to take it one hour before breakfast. I'm on 75 mcg, and my weight is doing great, my levels are normal if I keep on the medicine and take it like my doctor said to take it. I go to many different specialists because I have many medical problems, and I'm only 30, but this thyroid thing started after I had my daughter. So no, do not take it at night after meals because your body will not absorb the medicine. Correct, the medicine needs to be taken with a full glass of water and no food so it can work through."

"I've been on levothyroxine for a year now, and my life is so much better. When I graduated college at 21 and started working full-time, I was suddenly tired. All the time. Basic tasks made me exhausted. I always thought it was depression and tried counseling for years. I finally went to the doctor when I was 25 to get antidepressants, and she made me get bloodwork done. I had an atrophied thyroid! After about six weeks on levo, I had so much energy and even lost 10 pounds! Then it stopped working, so we had to adjust the dosage. I haven't had any long-term weight loss, unfortunately, but my energy is back up, and I wake up refreshed, which is exactly what I needed."

"I've been taking Synthroid for 3 years now. It was hard to reach the right dosage since I used to take Puran T4 (not marketed in the USA) 75 mg and had to adjust the Synthroid to 100 mg instead. I've been feeling great since!"

"I'm hypothyroid and skinny as a rail and cannot even gain a single pound, 58 yo, 5'6", 88 lbs, thyroid damaged through radiation, have been on Synthroid/levothyroxine 50 mcg daily, and I notice no change at all, still no energy, still totally exhausted 24/7, still losing weight like crazy with a relatively healthy appetite. However, since I totally trust my oncologist, I keep taking them."

"I have my hair, eyebrows, and lashes. I retain water. I feel tired often. But I sleep fine. Mood is stable. Weight is about 10 lbs over where I'd like to be, but not bad. Without this medication, I would feel way worse. I've been on it for 20 years. It's not perfect, but I can't live without it."

"I've been on this medication for a month. 50 mcg. It makes me so tired I can barely stay awake to work during the day. It makes it very hard to concentrate. I didn't have fatigue or brain fog before starting this medicine. It has improved my joint pains, itching, and the ringing in my ears."

"I've been taking this medication for years. It works very well in keeping my thyroid under control. I can always tell when I don't take it right, especially when my blood is tested. I have learned that I need to take this medication in the mornings, because that is when it works best."

"I was on Synthroid for four weeks after I had a prothrombin time (PT) test. I didn't notice much change until week four, and I developed pretty severe heart palpitations that I'm still getting on and off. My anxiety increased, and I had brain fog, bloating, and weight gain. I have been off of it for a week, and my numbers are double what they were prior to starting it."

"By far, the best T4 brand. I was first diagnosed with hypothyroidism while in Germany. There, I was given Euthyrox - which was absolutely terrible. So terrible that I decided it was better to stop taking the drug and face all the symptoms of hypothyroidism. It's worth mentioning that a class action suit against Merck, the German laboratory responsible for Euthyrox, was successful in France. Now, back home, my endocrinologist changed my medication to Synthroid (same active substance, different brand), and she also told me that many patients had faced the same thing while on Euthyrox. It's been a bit more than 6 months, and I'm feeling absolutely fantastic. Depression is gone, hair loss is gone, lost tons of weight. Recently, I had my dosage reduced from 200mcg to 175mcg. I take it systematically every day right after waking up on an empty stomach. Really changed my life. + I'm also taking Wellbutrin XL 300mg (for 7 years now) and cholecalciferol. No interactions or heart palpitations."

"I am a type 1 diabetic, 45 years of age. I have been on Synthroid for several years (now about 13) since I became a diabetic. I had a hysterectomy two years ago. I have been on Vivelle patches, Estradiol, Premarin, and for the longest, Enjuvia, and just recently changed to Estragel. For the last six months, I have been experiencing lifeless hair, breaking off. I have never experienced anything like this. I am very frustrated."

"If you boil up balsam tea every day for one month, you will cut your cholesterol and your thyroid down to where you don't have to take drugs. It's no quick fix, but it's a lot better than taking drugs. My wife is going off a lot of drugs and feels a lot better."

"I had a blood test 3 weeks ago, and I knew something was wrong. The doctor prescribed this to me. I don't know my numbers. I'm taking 25 mcg. I was tired before, but now I feel like I'm dead. Too bad you can't take this medicine at night. I never had a puffy face, but the cold bothered me a little. Very dry skin that developed over the winter. I used to have Addison's disease, which was easier to check with a simple prick of the finger."

"With my bloating, I also read that Synthroid might affect my intestines and cause me to not absorb vitamin to the fullest extent, and this might cause bloating. I now take 1,000 IU vitamins twice a day. My bloating is much, much better."

"I had a thyroidectomy after Hashimoto's for 20 years. I was on Synthroid for a year. Had severe joint pain and swelling in throat and abdomen (edema). I'm someone who never sweats, but on this med, that's all I did. Everyone said it was menopause, but since I switched to Levoxyl, that has stopped. Couldn't lose any of the 60 lbs I gained last year. It did get me to euthyroid, but I didn't feel it. Just started, so I hope Levoxyl will help me fit into my size 8s again."

"I have been taking .025 mg every day for two months. I was not sure why I was taking it. I know I had a super low sex drive and now have a high sex drive, whereas I have to relieve myself two to three times a day. I get very horny for no reason and notice my sperm is thicker and I'm producing a lot more now."
