Started off taking 25mcg of Synthroid, then upped to 50mcg. Starting Sunday (two days) I'll be taking 50mcg of Levothyroxine. I'm not sure why the change other than price(?) or synthetic over natural(?)...? A second question; are there any side effects I should know about from changing from one to the other drug?
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. Some people have problems with the fillers or binders the different brands and generic contain. This is true between brand names as well as between brand and generic.
Have you been feeling well? If so, it might not be worth it to rock the boat with any changes.
related to the change in medication, yes. Outside of that...
May 09, first blood test
Sept. 09, diagnosed with thyroid problems
Nov. 09, second blood test
Dec 09, Told numbers are better but still low. Doubled Synthroid till refill, then change of meds.
But what I'm wondering is if you are still feeling any hypo symptoms other than the voice changes...fatigue, constipation, low HR and/or BP, etc.
Do you have the actual numbers from your December bloodwork and the reference ranges on FT3 and FT4?
My basic thought is that if most of your symptoms are gone and you are doing well on the Synthroid, it might not be time to rock the boat by making an unnecessary change to generic, especially since you have just increased your dose. If you switch to generic, you will be throwing another variable into the mix, and you won't know if any changes are the result of the increase or the change in drugs. I'm a firm believer in the scientific method...control all but one variable.
I think it might be helpful if you listed your hypo symptoms on diagnosis versus current symptoms.
If you don't have any more symptoms, then I would seriously question doubling your dose, especially in light of your cardiac issues. If your doctor feels your levels need to go up, then a very slight increae might be in order, but a 100% increase might send you right into hyper (fast). We don't all do well at what our doctors think are the "ideal" levels. If your symptoms are gone, why increase at all?
