Is levothyroxine and synthroid the same
Common Questions and Answers about Is levothyroxine and synthroid the same
synthroid
I've been reading the previous discussion about generic vs branded medicine as it relates to hypothyroidism. I am on Levothyroxin and need to know if it's the same as Levothyroxine.
Thanks

To reduce the risk of an error, prescribers should print all orders for Lanoxin and levothyroxine and include the purpose for each drug on all prescriptions. Both the mg dose and the mcg conversion should be listed in all levothyroxine orders and on product labels, such as "levothyroxine 100 mcg (0.1 mg)" or "Synthroid 0.1 mg (100 mcg).
Another good one is Tirosint, which is a gelcap and contains only glycerine, water, Levothyroxine and gelatin. Tirosint tends to be the most expensive, but the manufacturer has programs for those who qualify.
Is TSH the only thyroid related blood test that's being performed regularly? What about Free T4 and Free T3? Those are the actual thyroid hormones.
Levothyroxine is generic. Synthroid is a name brand of the same drug. It is actually prefered by most Endo's, because it is a little more reliable from batch to batch.
It is made with different fillers than what you have been used to with the Levo. Some people do not get along with it. Lactose or something is in it.
It's possible you're allergic to the inert ingredients of the Synthroid.
Synthroid is the same drug as Levothyroxine. The Differences between the two are the fillers the manufactures use, and quality control.
Synthroid has better consistancy from batch to batch.
Levothyroxine is made by several different companies, and your med could change just by your pharmacy using a different supplier.
Synthroid is preferred over generic levothyroxine by most doctors that perscribe such medications.
As you noted, this is a very old post and I've seen the original poster on the forum for years, so it's unlikely you will get a response.
Maybe if you would start a new post of your own, others might chime in with their experiences, as I know there are some others who have experienced ear ringing.
Synthroid, Levoxyl, and other brands of generic Levothyroxine all have comparable doses.
If you switch brands from generic to Synthroid, the dose would remain the same unless your doctor changes your dosage for some reason.
I have the same problems! I have been struggling with chronic urticaria for nearly 2 years now. I have seen an allergist who tells me I have some allergies, but nothing to cause this sort of reaction and I have seen a dermatologist that FINALLY checked my thyroid antibodies (which were elevated) and sent me to an endocrinologist. I was diagnosed with Hashimoto's Thyroiditis and put on 25 mcg of Synthroid. Since I have been taking the Synthroid my hives have MAJORLY worsened.
t actually need the medication? The reason for my question is that I felt great a the time, was thin and only took Hormone replacement medication. After only a few months, I started having problems with depression, anxiety, panic attacks, which resulted in a full blown melt down. Since that time I have had joint pain and joint stiffness. In Feb. of 2003 I was referred to a psychiatrist (who is now one of my doctors). I have been to different specialists because of all my health issues.
My endocrinologist told me that using generic thyroid medications was dangerous, and to Never use it. Especially for me since I have had a total thyroidectomy and need a higher dose of hormone. He said that each pharmacy uses different companies, at different times, who uses different ingredients. He said some even have additives such as antifreeze. THis may be a far fetch but I don't wanna take the chance.
The active ingredient in levothyroxine and levothroid is the same; however, each manufacturer uses different fillers/binders to make the pills. Some people can have reaction to those.
I agree that there is debate over the use of generic vs brand name. I actually did better on generic levo than I did synthroid, but everyone is different.
just wanted to say that I was on Synthroid and generic Levothyroxine and it was ok for me for the 1st. month. Then I began noticing all the symptoms of hypo coming at me full force. So much so that I thought I was developing MS. Joint aches, dropping things, muscle weakness, major digestive gastro troubles,angina, hair loss and on and on... I just went today to a new MD who has been researching all natural alternatives other than the usual prescribed Synthroid.
Are you aware that the manufacturer of Synthroid and Lannet, a manufacturer of generic levothyroxine state that acacia is a filler and can cause an allergic reaction? There is also lactose and many do not realize this. I have been coughing for 18 years after starting on this hormone and seen countless of doctors and all stated nothing to do with the medication..that I have allergies.
