difference between levothroid and synthroid

what is the difference between levothyroxine and thyroxine if they both are the same dosage.

Hope someone can help. I have had low to no thyroid function all my life. I was on synthroid made by "flint" from the age of 4. When flint stopped making it I had to switch to the now "synthroid brand and have had several allergic reactions. My doctor switched me to levothroid made by forest and it was awesome no side effects no swelling in my tongue or throat. I had no swallowing problems.

Was dx with Graves disease almost 12 yrs ago and had the radioactive iodine treatment at that time. Was placed on thyroid medication and seemed to tolerate it with no problems with allergic reactions. For the past 5 months I've been dealing with medication problems and difficulty adjusting my thyroid levels. It went over active and then underactive. I've been on both generic and brand name Levothyroxine.

Now that I think about it again........I remember a difference between Synthroid and the generic Levothyroxine. One was soft and would almost get stuck in my throat as it fell apart, the other was like a pebble. Dont remember which one was which though......... You do have to grind up the dessicated with your teeth a little to speed things up from 1/2 hour to 10 minutes, its a little 'chalky', no big deal.

I think that everyone is different when it comes to dosage and how long it will take for your body to show some kind of difference. I had to be tested every 6 weeks with so may dosage adjustments. Just make sure you keep your appointments when it comes to checking the hormone levels.

I do have goiters also, but was told that when they enlarge i can switch between hypo/hyper and that over time my body will kill my own thyroid and i will become hypo. Is there really a need for me to take synthroid 25mcg for hashimotos? and will it go away. I'm so confused because i do have hay fever and asthma so is the synthroid even okay for me to be taking in the first place?

Thyroxine is, typically, dosed by mcg. Check your script again. 75 mcg would be the same as 0.75 mg.

Your way of thinking matched mine completely. I needed someone else to confirm my thoughts. I was able to return the Levothroid this morning (since it hadn't been opened and I hadn't taken any) and have the written prescription for Synthroid .150 mg filled. I will attempt to get an appointment with someone who is more competent ASAP. Hopefully, the next endocrinologist will spend more than 5 minutes with me in assessing the situation.

Synthroid, Levoxyl, Levothroid, Unithroid. Be careful though. They are the same main ingredient but use different "binders". Personally I cannot take the generic and only do well on the Synthroid - others are quite opposite. You will find many of us out here who swear by a particular brand (or the generic) and refuse to switch because of bad experiences. If you are going to switch, talk to your endo first so your labs can be monitored.

My husband is 40 year's old and has had hypothryoidism and hypoglycemia for several years. He takes one 200MCG tablet of levothroid every day. REcently, he started having severe chest pains. Last Sunday, they were so bad we took him to the ER where they performed all sorts of heart tests and determined it wasn't his heart.

Also, you may want to try the non generic synthroid, I have heard that it does make a difference or a different brand etc. My tsh is 4.63 and I am also increasing my dose a little, however I do not have the symptoms that you have, just a little,,,, tired I think.

I was astounded to find out that the retail price difference between real Cytomel and the generic is only about $8 a month. My insurance company has totally cheaped-out on me. Well, I guess that's not a big surprise, is it? {eye roll} Laters, kids!

I got my results to TSH tests and the doctor put me on Levothroid. My number was 2.6. Is this high or low? I was reading about the side effects and they are enough to scare me away from taking this medicine. I'd appreciate any help from anyone familiar with this drug. I definitely don't need to lose any hair and don't have the privilaedgo ot time to become nasty tempered or hyper. I have a husband to take care of and he drives me nuts at times through no fault of his own.

A TSH level of 9 would be considered high by my doctor and would indicate hypo. When do you go back to get your labs re done? I know my doctor once told me that I would not feel any effect of the thyroid medication until at least 2-3 weeks. I just changed my dosage as well to 100mcg of levothroid. I had started out at 200mcg about 14 yrs ago, but last two years have been having trouble getting my dosage correct. My TSH level seems to have been dropping the last two years.

Since then I have been taking Levothroid. I recently changed to 150 Synthroid. Recently, my lab results came back as follows: Result Range TSH 0.3 .2 - 3.8 T4 7.4 5.9 - 12.5 T3 uptake 40.5 22.5 - 37 T7 3.0 1.3 - 4.6 Vitamin D 21.6 30-100 Can you help me understand the T3 results that are out of the range?

I have been working really hard with my weight-loss, I exercise more than most people I know in my weight loss group, 65oz of water per day, 20-25 carbs, Veggies, Lean meats, no sugars, you name it, I've been doing it. I am also HypoThyroid and on 50mcg of Levothroid. My weight loss had been a upward battle, very hard battle. Anyhow, I spoke to a Dr. on the phone (My Dr. is out on leave), she looked at my chart and said that as we get older, we exercise less. I am only 35.

Levothroid, Levoxyl, Levo-T, Synthroid, and Unithroid are all name brand Levothyroxine drugs. I may be missing a whole other group of drugs, but you may be able to find one of the above. Best of luck.

I read your question and I am confused. You were on Synthroid and Cytomel. Cytomel is a T3 drug. Why did you want to switch? Why did your doctor allow that switch without testing you appropriately using the Ft3 and Ft4 and trying to just tweak your meds? Switching thyroid meds is difficult and now being on Armour - it may take you quite a while to stabilize on it. Without correct testing - it's a guessing game on where you may need to tweak your meds.

Most people need a TSH somewhere between 1.0 and 2.0. Everyone is a little different. 2.6 is a little high, and it is hard to say what the correct dosage for you with half a thyroid should be. 100mcg may be just right, or it may be a little too much. Without seeing all your labwork for the last five months, it's hard to second guess your doctor. I don't know your medical history or your body weight. I would feel more comfortable starting on a smaller dose.
