Question 1

is implanon effective while on levothyroxine?

Accepted Answer

Yes : Thyroid medication or any other medication does not decrease the effectiveness of  implanon.

Question 2

is it okay to mix levothyroxine and implanon?

Accepted Answer

If prescribed is OK: If you were prescribed levothyroxine for hypothyroidism, than there is no reason why you can not take it with implanon.

Question 3

have been on thyroxine/eutroxsig  for 20 years 150 daily. dr has given me new script for levothyroxine sodium. is it safe to change over.

Accepted Answer

Yes: It is essentially the same medication, just a different name.

Question 4

hi, i was wondering whether levothyroxine sodium has a limited shelf life; the reason i ask is because i am taking thyroxine due to expire in july?

Accepted Answer

Safe: Unexpired medication is still effective.
Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex, if you have sex.

Question 5

i'm taking 200mcg of thyroxine sodium daily for the past 12 years.if i switch to 200mcg of levothyroxine sodium instead, what will be the side effect?

Accepted Answer

Same thing: Hi. The only thyroxine sold as pure thyroxine is levothyroxine, so you should be fine. In other words, what was labeled as thyroxine was actually levothyroxine. After you make this switch, have your TSH and free T4 checked about 8 weeks later to assure biological similarity of the two different l-thyroxine preparations. Good luck!

Question 6

thyroxine sodium vs levothyroxine. which one is more effective?

Accepted Answer

Stick with one: Thyroxine sodium and levothyroxine are simply different forms of generic "synthroid".  Neither is better than the other.  Whichever form you take, stick with it.  The bioavailability of each thyroid preparation is a little different. If you switch from one form to another, your thyroid numbers may change, and you may start to feel hypo or hyper.  Sometimes pharmacists switch you to save $.

Question 7

before 1 month i was using levothyroxine 50mg,but now i take t4 thyroxine 100...will, increase of dosage,effect th perod to delay..its been 1 month?

Accepted Answer

Take pregnancy test: Are you from Sri Lanka? Just curious! If I understand correctly, you used to take Levothyroxine 50mcg but have since increased dose to 100mcg. Your period is now late so you're wondering if this is due to dose change, right? While thyroid disease can alter menses, I think it's more important that you take pregnancy test, assuming that you've engaged in unprotected sex. If not, irregular menses com

Question 8

i would like to know why manufacturer's use levothyroxine rather than thyroxine in their thyroid medications? levo has heavier sodium molecule

Accepted Answer

Thyroxine: 22M asks about diff between levothyroxine and thyroxine and notes Levo has heavier Na molecule. ANS: my recollection is that most Na is not of the heavy type.  Recommend you look at the chemistry of Na at wikipedia for more details about heavy Na.

Question 9

to what extent will taking fluoxetine decrease absorption of levothyroxine if both are taken at the same time? i know thyroxine should ideally be taken on an empty stomach, but sometimes i forget?

Accepted Answer

: Fluoxetine ‘s effect on levothyroxine absorption is limited. The medications that do seem to cause more problems with levothyroxine include antacids, iron, sucralfate, proton pump inhibitors, carbamazepine, phenobarbital, and phenytoin. Take your levothyroxine on an empty stomach; and take your levothyroxine 2 hours before or 4 hours after the offending medication.
