Long Term Effects Of Synthroid
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

After long term Synthroid (thyroxine) over dose of 200mcg for 5 years how long will it be till i feel better? Lowered to 175 cancer suppression.
patience required: With history of cancer (? Thyroid you did not mention ) , TSH stimulates not only thyroid cell also cancer cell , (tsh levels 0.3 to 3) need to know your age and weight , status of tumor to calculate the dose, 200 mcg i don't think is over dose, always needs adjustment , you may have associated diseases , speak to your doctor will make you better with other medication good luck. ...Read more
Can asgwaghanda be taken long term? Me thyroid dr told me 2 stop taking levoxyl (thyroxine) because my body is producing enough. He knows I take this herb
There is no: scientific information to confirm ANY benefits to taking asgwaghanda. There is no way to confirm that your thyroid levels would be normal without replacement if the lab tests were drawn while you were receiving replacement. The only way to tell for sure is to be totally off replacement for at least six weeks before lab is drawn. ...Read more
My 4 year old took 8 of my 200mcg synthroid (thyroxine). The p.A.-c said it would not bother him. But I am still worried. Is there instant side effects or longer?
Overdose: Call poison control right now. They will calculate how much he got according to his weight and they will tell you what you need to do and what symptoms he/she may have. Any time your child takes medications not prescribed for him/her always call poison control right away. The number should be in the front of your phone book. ...Read more
Just started on synthroid (thyroxine) (finally!!!) how long before symptoms improve (cold intolerance, brittle nails, hair falling out, constipation? What side effects should I watch for or expect? How long before dose increase?
I usually advise: my thyroid patients that it may be SEVERAl WEEKS for them to notice a "difference" and THAT is when I re-check the tests at 2 weeks to begin with! The "cold intolerance " is usually the first to "respond" BE PATIENT!!! It may take several visits before your problem is "sorted out" Hope this helps! Dr Z ...Read moreSee 1 more doctor answer
Weeks: Half-life elimination is 6–7 days for euthyroid patients; 9–10 days for hypothyroid patients; 3–4 days for hyperthyroid patients. That means that 1/2 of the drug hormone/medication still remains in the person 6-7 days after stopping the medication. The medication Levothyroxine is chemically the same as the naturally produced hormone thyroxine by the thyroid gland. ...Read more
Weeks: You may start to feel a difference in 1-2 weeks, but you need to give a new dosage 6 weeks before rechecking thyroid blood levels. ...Read more

Just started on synthroid (thyroxine) (finally!!!) how long before sx improve? What s/e should watch for or expect
I've been w/o my Synthroid (thyroxine) for 6mos now, i was taking 100mcg daily. How long do I have before it really starts to affect me and how serious can it be?
Should be already: The 1/2 life of synthroid (thyroxine) is approx. 30 days. That's why we check your TSH and ft4 levels 4-6 weeks after making adjustments. So the synthroid (thyroxine) is well it of your system by now. How serious will depend on how far hypo you will go and how sensitive you ate to the symptoms. Generally won't cause lasting damage, but you will feel awful. ...Read moreSee 1 more doctor answer
Not really: Absorption of each thyroid preparation is a little different, and you should not switch brands, if possible. But both synthroid (thyroxine) and Levothroid are long acting hormones, with a half-life of 1 week. I doubt you would notice a difference with regards to onset of action, for example if you were starting to take them for hypothyroidism. ...Read more
