Synthroid versus levothyroxine

Common Questions and Answers about Synthroid versus levothyroxine

synthroid

Her husband is a pharmacist, and he says their is a difference between synthroid and levothyroxine, and insists that she stay on levothyroxine. Is there that much difference between the two? I would think that if you are on one or the other nad stay with it, it shouldn't matter.
I'm currently on Levothyroxine and am wondering if synthroid is a better alternate.. Has anyone found out that synthroid was better than levothyroxine? Synthroid is more expensive so I really need to know whether it is right choice.. The only side-effects I am getting are occasional light headness and dizziness, which may or not be due to the thyroid meds....
Levothyroxine is the generic form of Synthroid. Both are synthetic, so price is probably the deciding factor. Many doctors don't like to use the generic because of concerns over variations in the amount of medication in them versus the stated amount. Supposedly, the brand names are much more consistent. However, whether this is true or Big Pharma just ran a very successful smear campaign against their competition is open to discussion. The medication in both Synthroid and levo is the same.
All Synthroid is levothyroxine sodium, but not all levothyroxine sodium is Synthroid. There are several "brands" of levothyroxine sodium... Synthroid and Levoxyl are the 2 main ones. Then there are also several manufacturers of generic levothyroxine sodium. All manufacturers are allowed a certain "tolerance", meaning their products can vary by a certain amount. Some argue that generics are not as good as brand names.
Levothyroxin is not listed in the pharmacuidical referrences I have looked at, except for a German one. Levothyroxine is listed as the generic form of Synthroid, Levoxyl, etc. The missing e on the end may be a typo or may be how a particular manufacturer markets their generic Levothyroxine.
My guess is that it's your increase that has caused the PVCs, not the generic versus Synthroid. I say this because you said you did fine on the generic for four years, so what changed was the dose, not the medication, when the PVCs started. I just couldn't tolerate levo without the beta blockers.
I started out on 25mcg Levothyroxine. Felt great about the 2nd month in, after the 3rd mo, I started feeling as exhausted as before. Had blood work done again and the Endo doc said my #was still a little lower than she'd like, so she put me on 50mcg Levo. I feel no better whatsoever. Pathetically drained, no energy, always tired, and NOW I am experiencing large amounts of hair being shedded in the shower especially. It is disturbing how much is lost in the shower.
You should stick with one or the other and make sure that you are given that always. I started on Levothyroxine and Cytomel then changed to Synthorid. I personnally had issues on Synthroid and have since moved to Levoxyl. There can be differences and potiency issues between meds, and switching all the time can be problematic to some.
my 17 year old daughter with Graves Disease since diagnosed Feb. 2007. She is currently taking 30 mg. of methimazole and .075 mg. of levothyroxine per day. The endocrine clinic says that her thyroid levels are slowly getting closer to normal. We took her out of school in Feb. due to severe anxiety and some depression related to Graves, and she has been doing a bit of homework through a homebound tutor. Last month the endo.
Hi, I have had Hashimoto's for years and seem to be having a sudden sensitivity/intolerance to Synthroid. This developed since my hyperthyroid bout last spring and swing back to hypothyroidism. Every time I increase my dose, I experience horrible hyper symptoms including sleep difficulties, heart palpitations and tearfulness. However, the dilemma is that if I don't increase the dose, the hypothyroid symptoms persist. My TSH is slightly below 3 and the target is 1.
In a randomized trial comparing PEI and TSH-suppressive doses of levothyroxine, significantly greater nodule shrinkage 12 months after treatment was found in the 25 patients treated with PEI (reductions of 47% with PEI versus 9% with levothyroxine).[73] The same authors later compared two groups of 30 patients who had small, solid nodules (mean volumes 9.9 ml and 9.4 ml, respectively). The first group was treated with a single PEI whereas three injections were administered in the second group.
I do not know what my exact numbers are but I had A ENT Dr. that removed the side of thyroid that had a benign tumor. He said I would probably never have to take synthroid, then I had a lot of bad episodes of crying alot waking up scared in the middle of the night and heart palpitations and scared I was dying. He ran a blood test and gave me 150 mcg of the generic, he did bloodwork like 3 weeks later and lowered it to 100mcg,told me to go back to work and did not want to see me until Nov. 28.
Also, is there a difference between levothyroxine and synthroid other than formula versus generic cause I have heard synthroid works better than levothyroxine. Any information would be appreciated.
It is Levothyroxine which is just like Synthroid....it is made in Mexico. Is there a reason why you are asking?
When I was tested, my PCP called me at home and changed my meds back to Synthroid on the spot. How do you feel about synthetic replacement versus natural replacement? Any time I mention a symptom to my doctor, I feel like he honestly thinks that I am a hypochondriac so I hate to even go in and see him---other docs do the same as well. I am a reasonably healthy 50 year old woman who just wants to feel good again. I know I can if I can just convince a doctor to really listen to me.
so he looked and said this is not the same medicine I said WHAT...so we went back the pharmacist that synthroid is $25.00 the levothyroxine is $5.00 and right now that is a big difference for me with no job. I asked her all kinds of questions. She said yes normally you should stay on the same med's continously however, since i have really just started and the fact the doctor was changing the dosage it really should not matter.
THIS is what levothyroxine does to ME. The first day in which I dropped Synthroid down to 6.25 (the lowest dose yet), as quickly as the symptoms above had come on, they ceased that quickly. I've even been able to raise Naturethroid from 30 mg to 37.5 mg with no profound symptoms whatsoever. That's not to say I have NO symptoms. I guess now I have what would be appropriately be called "typical" hypothyroid symptoms, i.e.
Do I need to be concerned with generic versus brand name levothyroxine? At my age and this level of levothyroxine is hair loss still a side effect?
) But research reported in the journal Clinical Endocrinology found that taking the same dose of levothyroxine (i.e., Synthroid) at bedtime, as compared to first thing in the morning, might be better. The small pilot study was prompted by observation that some patients had improved thyroid hormone profiles improved after they switched from taking their levothyroxine in the morning, to bedtime.
Before the Tirosint, I was on generic levothyroxine; before that I was on synthroid. I'm not sure what thyroid replacement hormones are available in Pakistan, but I'm sure your mother would be put on a T4 medication to start with, then have blood tests in about 6 weeks to see what her levels are.

My doctor did order me Synthroid 100. mc for the HYPO. I was using levothyroxine but i was fluctuation way to much with thyroid issues. I really do believe that it was generic. Any suggestions. I really want my life back.
Unless taking Cytomel, in which the blood circulating level of T3 change rapidly, therefore the dose can be adjusted more often than Synthroid/Levoxyl. Therefore, it is recommended to check your blood level every 3-4 weeks versus every 6 weeks http://intramural.niddk.nih.gov/research/celi/faq.htm "Serum TSH measurement after six weeks will indicate the need for dose adjustment by 25-50 microgram increments.
