Thanks very much for your advice. I will contact gp re full iron panel and all other suggestions. I do also have teva candesartan 16mg but I dont know if any problems with this. Problem is they quite frequently change the brands so I will ask for the same brand.
Many people find Levothyroxine brands are not interchangeable.
Once you find a brand that suits you, best to make sure to only get that one at each prescription. Watch out for brand change when dose is increased or at repeat prescription.
Many patients do NOT get on well with Teva brand of Levothyroxine. Teva contains mannitol as a filler, which seems to be possible cause of problems. Teva is the only brand that makes 75mcg tablet. So if avoiding Teva for 75mcg dose ask for 25mcg to add to 50mcg or just extra 50mcg tablets to cut in half
Physicians should: 1) alert patients that preparations may be switched at the pharmacy; 2) encourage patients to ask to remain on the same preparation at every pharmacy refill; and 3) make sure patients understand the need to have their TSH retested and the potential for dosing readjusted every time their LT4 preparation is switched (18).
Levothyroxine is an extremely fussy hormone and should always be taken on an empty stomach and then nothing apart from water for at least an hour after
Many people take Levothyroxine soon after waking, but it may be more convenient and perhaps more effective taken at bedtime
No other medication or supplements at same as Levothyroxine, leave at least 2 hour gap. Some like iron, calcium, magnesium, HRT, omeprazole or vitamin D should be four hours away
To work out how far through a reference interval (range) a result is, we need to do the following:
Find out how big the interval is. That is, how far it is from the bottom to the top of the interval.
If the reference interval were 3.1 to 6.8, you would subtract 3.1 from 6.8 giving 3.7.
Then work out how far from the bottom of the interval your result is. If your result were 4.8, then subtract 3.7 from 4.8 giving 1.1.
Now what percentage is your result (1.1 up from the bottom) of the interval (3.7)? Divide 1.1 by 3.7. Which gives 0.297…. And multiply that by 100 to convert it to a percentage. 29.7 – near enough, 30%. Which is almost a third.
