User Reviews for Synthroid oral

I couldn’t really tell if it did anything at all.

In the very beginning of use there is some hair loss, however that goes away after 3 months. All has been well with this drug.

Does not work for me and caused more health issues and more hair to fall out. Been on it for almost a year now. Asking doctor to change medication

On daily synthroid and simultaneously complaining for 10 years. Have been taking it intermittently the last 2 years but not feeling better. Just quit entirely in April 2023 and finally improving. Since I quit my fingernails are growing like crazy and my hair stopped falling out. I've gained maybe 10 lbs but who cares!

I have a terrible reaction to synthroid 25mcg but my Dr said I needed more so up it to 37.5 but this medicine is making me way worse than I was before starting the medicine I have terrible brain fog sick to stomach blurry vision bad joint pain then when I did up it to 37.5 and the bad chest pains and racing heart pulse would be 145 at times then terrible sweating so tired but can't sleep. I know I can not continue taking this medicine it is making me physically sick and the anxiety is terrible just putting this out there so other people don't think it's just them. Iam in the process of trying to get tested to see if I am sensitive to something in the medicine. I was so hopefully this medicine would help but nobody wants to take a medicine that is making them feel terrible.Read More Read Less

I can’t take this medicine at only 25mcg my heart is pounding out of my chest pulse is 145 terrible brain fog sweating really bad and joint pain I feel worse now then I ever did before I started this medicine has to be a easier way to do this.

There are 10 or 11 additives in Synthroid. MANY people are allergic to these additives. I am.

I am currently back on Synthroid, and I'm having so much trouble tolerating it, once again. Not my first time on Synthroid, but I've been on so many of the other thyroid drugs (both synthetic & natural), and none of them work right on me. So, I end up on things that have failed me, over and over. We adjust doses, etc, but it still doesn't work right. And I must have some sort of thyroid-replacement medicine, as I don't have much gland functioning due to RAI for Graves' Disease, when I was eleven and twelve (back in 1975-76). The sad thing about Synthroid is there used to be a different version of it, which they stopped making in 1982-83, just to be "cost-effective" according to one thyroid professor at UC San Diego Med School that I went to....and the old stuff worked so much better on me. Nothing has helped right, since. All these drugs now tend to give me symptoms of hyper and hypothyroid at the same time, and this current version of Synthroid is no different. That's why I'm up so early this morning, not sleeping well (again) and getting bad nightmares, which seem to go away if I go off Synthroid for a day or two...but come back when I return to it, even at a lower dose. Current version of Synthroid also seems to be raising my blood pressure too much....I will have to keep lowering the dose, even though labs say I need more medicine. I just can't handle it. Also can get heart-pounding; too much nervousness; depression; very dry and coarse hair; too much swelling; eye problems; appetite is off; too cold, generally. It is horrible to have to go through such a time, every day, and then see the symptoms get "magically" improved if I go off the medicine for a day or two...but I know I'm doomed to have to be on something, because of my lack of functioning thyroid gland. I'm happy for those on here who write that Synthroid really helps them. I remember that feeling, from how the Old Synthroid used to help me, before 1982. But the Newer versions of Synthroid since that time (and all the other thyroid drugs I've been on) do NOT help me like that; they hurt me in many ways, no matter the dose. And that's an incredibly hard thing to deal with....I shouldn't have to; and neither should the rest of us who don't have a useful drug for us, that really works. It's one of the reasons I started a petition to get better treatment for thyroid patients. Don't know if they'll let me post a link to it, but it's here https://www.change.org/ThyoidBetterTreatment If link doesn't work, google "Thyroid Patients Need Better Treatment Now" and it's on the petition platform called Change dot Org (the dot is a real period, when you type it) I mainly started it in memory of my brother, who didn't get his thyroid trouble caught early enough and treated well enough. I'm trying to get the White House to help us with better drugs, better and earlier testing for thyroid problems, etc. People like me need help, too, and I know others could use better meds or maybe some innovative treatments to help us. Thanks for reading, and for maybe signing & sharing my petition. I will be skipping most, if not all of my Synthroid today....and yes, my doctor knows my situation. He doesn't seem to be able to do much for it. Read More Read Less

I was diagnosed with hypothyroidism. 25 mg of Synthroid. I have now gained 60 pounds. Severely depressed. My option is to increase so I will then make sure I have a heart attack. Other option stop the drug and ensure I have a heart attack. Worse drug I have ever been on. While still on it I can’t sleep, have tremors, am freezing all the time., shower hurts my skin, depressed, anxious and as I said an added 60 pounds. So as I see my doctor next week. Would rather go off of this terrible drug. Lost the weight in a healthy way. And apparently have a heart attack. Yep great drug!!Read More Read Less

I'm not sure what is going on, every few years my thyroid goes haywire, my TSH hits the bottom of the charts so my Synthroid dose has to be increased a lot. Then all goes back to normal numbers for another year or so.

I have been on a dose of 50 mcg of levothyroxine for almost a year now and it is the worse drug I have ever taken. I sweat all of the time, my joints ache, my short term memory has decreased and my blood glucose has increased. The blood glucose increase started the week I started this drug. What I can't believe is that endocrinologists so readily prescribe a medication that they must know increases blood sugar ( there are many peered reviewed journal papers that report this). I'm in the process of switching endocrinologists in the hope of finding one I trust.Read More Read Less

I have been taking Synthroid for over 44 YEARS. My lab results always run high, but I look and feel fine. My DX is Hashimotothyroiditis. It is difficult to find and talk to a Dr. who is willing to treat the "symptoms" as opposed to relying on strictly lab results. Now I am faced with having to switch to a generic form, and I am concerned that I will still feel the same as I do now taking Synthroid.

Stay away from this drug, unless you literally have no other options helping your health with good foods. This drug will cause Osteopenia, if taken over long periods of time on a daily basis. After Osteopenia, next comes Osteoporosis. First hand experience, and your Doctor may no even tell you about this known side effects! I took myself off this drug, reversed the effects, eat healthy, and consider others to be cautious if they have to take this drug. There are natural ways to help Thyroid issues, taking this drug should not be the option, unless you have no other choice! Read More Read Less

I was taking synthroid and experienced a severe allergic reaction to the other ingredients, acacia, aluminum, talc and possibly a gluten like substance. I am switching to Tirosint which only contains the necessary ingredients plus glycerine. It is pure without things like food dyes, aluminum, acacia etc. and cleaner, more effective.

I had a severe allergic reaction to using Synthroid. I am celiac and have asthma but both controlled by a gluten free diet. Synthroid contains both acacia and I suspect another unknown ingredient that triggers my celiac, in addition to aluminum, talc and other weird stuff. Plus no noticeable improvement in my thyroid condition.

I was diagnosed with graves. Total thyroidectomy 2009. I now have both hypo and hyper symptoms. insomnia,neuropathic pain in shoulders and neck, agitation, anxiety and depression not to mention the mania ( _ )

I had RAI for hyperthyroidism. Started taking levothyroxine as directed and religiously. This stuff is poison. Had symptoms of body tremors, severe pains in leg, general body pains and, the worst symptom of all, debilitating depression. Having to continuously up the dosage is ridiculous. It is NOT natural and harms the body. I switched to ndt and started feeling better within one week. Suffering needlessly is a pitiful thing to do. Having a doctor who ignores your symptoms (when you know your own body) is also cringeworthy. Find a professional to listen to you and one that will treat you with respect to your being an individual. Itâ??ll change your quality of life. Read More Read Less

My hair falls out, I have gained weight without increase in food intake. Constantly tired-exhausted

I visited an endocrinologist for diabetes issues. The endocrinologist also ran a Thyroid panel and started me on Synthroid because my TSH was at 10.5. Dosage started at 50 mcg and was gradually increased over 3 months to 125 mcg. TSH is now at 3.8 and other Thyroid tests are in the normal range as well.

Had RAI for Graves in 1996. Continuously increasing my dose of Synthroid since until now at 175mcg, I'm 5'3" and weigh 130, constant fatigue, hair loss, dry skin, constipation, gained 10 lbs while eating much less, brain fog and have I said CONSTANT FATIGUE! The ONLY thing that helped was adding Cytomel T3 to my dosing...this has been a LIFESAVER! I feel many thyroid patients just go with whatever their MD's push them to take, according to what the pharmacy reps push on them. ALL thyroid patients NEED to go with how they feel and not just what MDs want to push on them!Read More Read Less
