Question 1

my dr.is switching me to synthroid 125 mcg from levothyroxine 125 mcg..2016 total thyroidectomy
we discussed this because my t4 sometimes is off and i have been fatigue. is there any side effects i will feel with the change.  thyroidectomy. nervous?

Accepted Answer

Relax: The two meds are the same thing at the same dose. One may be labeled differently or be a generic. It is confusing why you think your meds were really changed. Please clarify this with your doc.

Question 2

i was just diagnosed w/ hypothyroidism & my tsh was 16.33. how severe is that? i was prescribed synthroid (thyroxine) 25 mcg but am still feeling side effects of hypo

Accepted Answer

Not severe.: This degree of TSH elevation denotes significant but not particularly severe hypothyroidism.  Your initial dose of synthroid (thyroxine) may be a bit shy of what you'll eventually need.  Your TSH level should be rechecked after 6 weeks of treatment.  As your TSH gets into the normal range, you should be feeling better.  Give it some time.

Question 3

what is the principal side effects of synthroid ?

Accepted Answer

Side effects: There usually are not many side effects of Synthroid. If the dose is too high however, then you may have weight loss, agitation, tremors, looser stools, sweating.

Question 4

what are the common side effects of synthroid (thyroxine)?

Accepted Answer

There are none: Synthroid (thyroxine) is a man-made replacement for your own thryroid hormone. There are no side effects per se because the drug will bind to the same receptors that your thyroid hormone binds to so the body does not use the drug as a synthetic. It is possible to take too much Synthroid (thyroxine) and then have effects of excess thyroid like rapid heart beat.

Question 5

what are side effects of too much levoxyl (thyroxine)?

Accepted Answer

Hyperthyroid: Too much Levoxyl (thyroxine) can give you the symptoms of hyperthyroidism. Most importantly it can cause osteoporosis . You can have a rapid heart rate, tremor, diarrhea , hair loss, elevated blood pressure, anxiety and weight loss among others. It is important if you are on this medication to see your doctor regularly and check your thyroid levels.

Question 6

what are the side effects of levoxyl (thyroxine) hormone?

Accepted Answer

None: If the dose is appropriate, there should be no side effects of thyroid hormone replacement.  The body does not differentiate a normal amount of thyroid hormone coming from your thyroid gland or from a pill.

Question 7

how many weeks after beginning 25mcg of synthroid (thyroxine) can side effects occur?

Accepted Answer

Thyroid treatment: 25 mcg of levothyroxine is a very low dose; a normal dose for hypothyroidism is typically much higher.  The only side effect is taking too much (hyperthyroidism:  palpitations, sweating, tremor, etc) or not taking enough (hypothyroid:  fatigue, cold, etc).  But such symptoms can be from other things.  You need to get levels checked and talk to the doctor who initially prescribed this.

Question 8

is one of the side effects of levoxyl (thyroxine) insomnia?

Accepted Answer

Possible: Levoxyl (thyroxine) can potentially cause insomnia, especially at higher doses.

Question 9

i have to stop taking synthroid (thyroxine) for a thryroid scan test.  what are the side effects, i have been on medication for 8 years?

Accepted Answer

Mild if any symptoms: Synthroid (thyroxine) replaces hormone normally made by your thyroid.  It helps maintain body heat, metabolism, energy.  Stopping medicine for a a few days may make you mildly fatigued, a bit sensitive to cold, and less hungry, but should not cause serious symptoms.  Some people don't even notice the difference especially in warm weather.

Question 10

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?

Accepted Answer

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.
