Anyone that had tried the New Teva experienced that it was stronger than other brands? I suspect that it was for me. When I tried 75mcg my results showed a little over dosed. But now I'm back on Mercury and taking 75 every 3rd day and the other 2 62.5 and my symptoms are coming back.
Anyone experienced this or similar?
Blood results don't inform us how we are 'feeling' which is the best way to know if a dose suits you or not. If symptomatic we need an increase and if feeling hyper reduce dose slightly.
Also if ten people took the same dose by the same manufacturer they may all have slightly different reactions so it's difficult to know whether the tablet is 'strong' or 'weak'.
Lisan1,
If you were taking 75mcg Teva daily then you were getting significantly more Levothyroxine than your current dose.
Perhaps you could try 75mcg/62.5mcg alternate days.
I think you may have changed the dose now on MP whereas in teva you were taking 75mcg each day? One thing I've found is that I do much better taking 87.5mcg every day than alternating 75 and 100 - I felt underdosed on 75 but trying to reduce slightly as 100mcg every day wasn't good in the long run. You may like to try evening your dose from day to day as much as you can and see if it works?
Interestingly, I think that 100mcg Actavis may not equal to 2x50mcg Actavis, possibly being stronger. A couple of people on here had reactions indicating it (you can find in my replies if you're interested) but I haven't yet verified on myself as I've changed from 100mcg actavis to MP smaller tabs I had left over and my doses have been all over the place lately...
Your question is interesting to me. I have been taking Teva 12.5 microgram tablets (plus the same 100 microgram Actavis I have been taking for a long time). I feel different - and think that they are having a greater effect than the other make 12 microgram tablet I had been using for ages. That is, I think I feel slightly over-medicated - and I do not like that feeling at all.
Am currently back on the old make and seem fine again. Need a bit longer to be sure.
helvella , do you think there's a possibility that it may be the 100mcg actavis that's too strong i.e. something changed in the formula or dodgy batch? I got a spaced out, light headed sensation also as if a lens was focusing in my attention when I was on actavis 100mcg (actually, have taken it again for 2 days and think I'm starting to sense it again).
I'm running out of my stash of MP and the teva 25mcg tablets are next on the list - if they are much different to MP it will throw yet another spanner in the mix😉
Well, I don't think so. I have been taking Actavis 100 for a very long time. I simply switched the small tablet to Teva. Even using tablets from the same Actavis pack!
Trouble for me is that whilst I am convinced that there are differences in how I feel depending on exactly what make tablets, etc., it is far more difficult to be absolutely certain that it isn't other factors. Like the weather, the wind, what I have eaten, ... Those who change medicine and notice big changes suffer far more but it is easier for them to be sure!
Yes totally! You and me are in the same boat I think - sensitive to small changes. Still, wondering all the same if our observations are correct and how best to interpret all variables😉 I'll be keeping an eye on the actavis 100mcg though as there is something about them that doesn't seem to agree with me...
Hi lisan1, Would you mind emailing me about this please? enquiries@thyroiduk.org Thanks! Lyn
Hi I recently was dispensed TEVA new formulation 25mcg and had to stop taking them after 7 days due to extreme gastritis symptoms. I also felt more hypo for a good 2 weeks after I had stopped them, but had not felt hyper whilst on them. I am now on Wockhardt 25mcg & MP 50mcg in combination with Liothyronine 10mcg. Last year I was on MP 100mcg before I saw Endo & was put on combo therapy - I am convinced the fillers have an impact!! I am experiencing more joint & muscle aches & pains! Is there a 75mcg tablet available on NHS??

EveP, The only 75mcg levothyroxine tablet available in the UK is the one recently introduced by... guess who... Teva 
Thank you Red Apple Definitely not using that then just cant win with these thyroid issues!! Getting medichecks bloods done before my Endo appt. in April cause neither he or GP or Lab will test FT3!! Despite being prescribed it!! The professionals just dont get it or cant cause of the powers that be sorry for the moan just feel its 1 step forward & 2 back!! EveP
Totally understand When it comes to thyroid issues, the 'professionals' are most definitely not getting it. And generally they truly don't seem to want to get it either. So we have no option but to go the self help route. Thank goodness this support forum is here for us all to share and help each other.
