Reviews for Synthroid to treat Underactive Thyroid
"MUST be taken at night - and it absolutely seems to work for me. No more brain fog - and for someone who was always a go getter - the brain fog was devastating. No more night sweats either. Those were the worst."

"Diagnosed with Graves disease, my thyroid was radiated and destroyed. Put on synthyroid, took a while to get dosage right, but I have been on it for 8 years now and without it I would want to die. I take 100 mg a day and I set my phone alarm to go off same time every day so I won't forget it."

"For the first few years I had my OB/GYN monitoring my thyroid and adjusting my Levothyroxine… What a mistake! I never felt good and come to find out he was doing it wrong. Not doing the right test to monitor my levels and decreasing my dose when he should've been increasing. I started to see an endocrinologist and WOW! What a difference. He switched me to namebrand Synthroid only (which made a difference) and checks my levels twice a year to make sure I'm on the correct dose. I feel amazing for the first time in years!"

"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/levothyroxin 50 mcg daily, and I notice no change at all, still no energy, still totally exhaust 24/7,still losing weight like crazy with a relatively healthy appetite. However, since I totally trust my oncologist, I keep taking them."

"I can almost guarantee that most of these negative reviews are due to either 1. Taking the medication incorrectly (generic works for some not all), too close to food or iron,calcium, some antidepressants interfere) 2. Taking the incorrect dose 3. Not being consistent(must be close to the same time daily ) I had gone through many changes before finally getting it right. Seems to be working good after getting on brand name and taking it seriously."

"I just started this medicine about a month ago. It is making such a big difference in my appetite and my energy. I am a fairly young man at 23 years old. I knew something wasn't right with my body over the last few years, as I had gained about 30 pounds over the course of just a few months and felt so sluggish. It turns out, like many of you reading this, I have an underactive thyroid. I have heard that three drugs help with the thyroid hormones. Synthroid (T4 hormone), Cytomel (T3 hormone), and Armour Thyroid (T4 & T3 Hormones). Synthroid has gotten a bad rap because it's synthetic and it only covers the T4. Well, the T4 is most likely all you need because a T3 deficiency is rare. Synthroid is great. Stomach upset went away in 1-2 weeks."

"Before synthroid I was achy and tired. Now I have headaches...bloating...stomach pain...loose stools and the feeling of being in a fog. I'm only on day 4 of the lowest dose cut in half. I'm stopping it. I was put on it before and it made my heart go to sinus tach but the new doctor insisted I try it again! Hell no! I felt better before the medication!"

"Since being diagnosed with "Hypothyroidism"(1999). 1st was given antidepressents for being tired and gaining weight (eyeroll). Have been on 88mcg's of *Synthroid-daily.My blood work has always come back with my TSH at the HIGH-end of normal. Former Dr retired years ago so no continuum of care (walk in clinic). Recently new Dr suggested we adjust meds to bring down the TSH level. Started with 100mcg *Levothyroxine 5 days & Synthroid 88-2 days a week.In a few months time I suffered some pretty severe side effects-EXTREME dizziness/weakness,lack of energy,mood extremes,weight is either climbing or stagnant,racing pulse/heartrate.We checked levels & now TSH reads at the extreme low end of normal.I'm scared please help."

"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."

"While it brought the TSH into the appropriate range, the exhaustion, lethargy, constipation, etc. was unbearable. For 20 hours out of the day, felt drowsy, unmotivated and sleepy. This is no way to live. Got on Tirosint and what a difference."

"I began taking my Synthroid three weeks ago and I feel great. First I began breaking my 25 mcg pills into quarters and started out taking only a 1/4 pill. I do this in the morning with a glass of water. I am now taking one 25 mcg pill. My sleeping has improved, I have more energy, my skin looks better and my face does not look tired,. I refused to take this drug initially when I was first diagnosed in 2011 because of a bad scare taking the generic brand, so I let my new meds sit for six months before trying this brand. It works wonders for me and being a life-long gym and karate guy, I have more energy to do laps in the pool and do weights too. I have taken iodine and it works ok, but nothing like my Synthroid. Time will tell."

"Had partial thyroid removal with benign tumor 30+ years ago, was OK until about 2 years ago and routine bloodwork showed low thyroid. After 2 years being OK on the medication suddenly the thyroid levels are dropping again, hair falling out, skin is breaking out in itchy red welts, gaining weight, so Dr upped the dosage. A couple weeks on higher dose I feel like I am "wired" in high gear, can't sit still, talking to myself going in circles, and my hot flashes have really really ramped up big time. Dr. says to give it at least 60 preferably 90 days to adjust, not sure I can hold out that long before stopping it. Hoping there is a better solution out there someplace."

"Reading all the posts/comments on here - PEOPLE - if you are still feeling bad and not noticing relief from symptoms of an underactive thryoid PLEASE TELL YOUR doctor. If your doctor disagrees with you then find an ENDOCRINOLOGIST to get a second opinion. They specialize in endocrine issues which the thyroid falls under. You know your own body better than your doctor - research the symptoms of an underactive thryoid and if you are still feeling them - then get a second opinion. Never stop taking this medication on your own, it takes 4 to 6 And be aware that when you start this m weeks to notice a difference in your body. Also, ask your doctor to write DISPENSE AS WRITTEN on your prescription to avoid the pharmacy giving generic"

"Although Synthroid keeps my test results "normal" I still have all of the hypothyroid symptoms. Severe exhaustion, sensitivity to cold, trouble concentrating, etc...like I haven't experienced since before I found out I had hypothyroidism. I was only put on Synthroid since the medication I am normally prescribed is no longer available."

"I started taking Synthroid about 6 months ago and I feel really good. I went from feeling like a zombie to feeling like my normal self again. Before starting on Synthroid I had most of the typical hypothyroid symptoms...tiredness, dry skin, cold intolerance, puffy face, etc. Now the only symptom that still bothers me is water retention. My Dr. just increased my dose so hopefully that goes away soon."

"Only been on this medicine for 4 days and it has already made a huge difference in how I feel. The depression was awful and the intolerance to the cold was bone chilling. I hope things continue to look up. So far so good!"

"Synthroid saved my life....been taking it for almost four years now. I had all of the worst symptoms in the worst way of a basically dead thyroid. I was feeling better within a week of taking it and continued to feel better and better every day for about the next six months. That's when it leveled off and I've been happy (and grateful) ever since. It took about a year or so to lose all of the weight I gained as a result of crummy thyroid. The weight just came right off after taking Synthroid. I'm on 225Mcg per day with very minimal side effects...so minimal that I can't recall what they are at the moment."
