How long after getting proper dose of synthroid (thyroxine) should I begin to feel less symptomatic? last tsh was 23.

How long after getting proper dose of synthroid (thyroxine) should I begin to feel less symptomatic? last tsh was 23.

Usually on the order: Of two to three weeks. But I should warn you there are some patients that some neuromuscular and psychiatric symptoms can take months to resolve. It's also possible that some symptoms thought to be related to hypothroidism like fatigue or weight, may in fact be related to other factors/issues, even when the hypothyroidism is corrected. ...Read more

Personally: I would not give synthroid (thyroxine) to my dead dog. As a MD I take Armour Thyroid, porcine desiccated thyroid; my last five years. For a detailed explanation go to www.Mercola.com search diagnosis and treatment of hypothyroidism. You need a Serum Free T3, Free T4 and TSH. Armour Thyroid is far superior. Also search Mercola.com 'Armour thyroid" ...Read more

Recheck in 6 weeks: Don't forget to have your level rechecked 6 weeks after the change in dose, to insure further changes are needed. Make sure you're receiving brand name synthroid, (thyroxine) not a generic. ...Read more

NO: Your labs suggest you are on the right dose of synthroid. When you take it ( should be in the AM) can affect sleep. If you are taking it correctly, I would recommend exploring other causes of your wakefulness ...Read more

My TSH level was 5.82 when I went to doc and I was put on Synthroid (thyroxine) 50 mcg. Is this the correct dosage? My TSH is now 3.41 is that normal? T3t4 r norm

Kind of...: There remains some debate about what "normal" really is for the tsh. Years ago the "normal" was somewhere between 0.5 and 5.5. I don't think anyone thinks 5 normal now. Most labs have brought the top end to about 4.5. I now use 3.5 as top end of normal but if i already have someone on meds i'll try to get them somewhere between 1 and 2ish, especially if they continue to have "thyroid" symptoms. ...Read more
