Hi which brands of Levo are there please? I have been experiencing some digestive upset on a lactose free one called Teva and I had my dose reduced to lessen the digestive symptoms.

I was diagnosed hypothyroid in 2011. I have lactose intolerance as well. Thank you

Reducing your dose will undermedicate you. If you are intolerant to Teva you should ask your pharmacist to exchange it for another Levothyroxine make or get a new prescription at the original dose and get one of the makes below.

Mercury Pharma 25mcg, 50mcg, 100mcg

Actavis (also known as Almus and NorthStarr) 50mcg and 100mcg.

Wockhardt 25mcg.

You can make a yellow card report re the adverse effects of Teva via yellowcard.mhra.gov.uk/

I have been on Mercury Pharma, Actavis and Wockhardt

I am lactose intolerant.



Teva is the only lactose-free Levothyroxine in the UK.

Have you tried any of the others?

I tried Thybonn Henning which I think is German lactose free levo but GP prescribing it said it was taking too long to be ordered in so refused to prescribe it on repeat.


Henning Thybon is NOT levothyroxine (T4). It is liothyronine (T3).

(There is Henning L-Thyroxin - which is T4. But is is not called Thybon.)

I can't remember what he said about the Thybonn, sorry

Endo aware I have undermedicated results, no increase suggested

Endo said I am not absorbing levo very well with the Actavis, Mercury Pharma and Wockhardt brands. Lactose deficiency was confirmed and he put me on Teva which improved my levels but made me feel awful.


Ask endo or GP to prescribe one of the European lactose-free Levothyroxine tablets in thyroiduk.org.uk/tuk/treatm... via named patient basis prescription thyroiduk.org.uk/tuk/treatm... or ask for a prescription for liquid thyroxine which doesn't have fillers.

Thanks my endo will not prescribe any European lactose free tablets and will not give me liquid levo


If you'd mentioned this in your opening post we wouldn't have needed to play 20 questions.

Options appear to be:

1. Ask your GP to reinstate prescription for Thybon. It shouldn't take more than a few days for a pharmacy to obtain it from Germany or one of the specialist importers.

2. Write to the head of endocrinology or the hospital PALS and ask them to intercede with your endo as you have confirmed lactose intolerance and arrange for European lactose-free Levothyroxine prescription or liquid thyroxine and for assignment to another endo.

3. Buy NDT online if you can find one which is lactose-free. Brands and ingredients are in stopthethyroidmadness.com/a...

Sorry but I feel like a pest to the endo

Taking 25mcg levo Teva, very symptomatic

Previously taking 150mcg, endo said it was just as well since my TSH was 0.03 (0.2 - 4.2) FT4 25.3 (12 - 22) FT3 3.9 (3.1 - 6.8)


What do you suppose he meant by that?

Current results on 25mcg

TSH 4.69 (0.2 - 4.2) FT4 14.8 (12 - 22) FT3 3.2 (3.1 - 6.8)


You are undermedicated. I suggest you dump your endo. He's obviously not helping you at all. The FT3 range is wrong by the way.

Might as well die then

Yep, clearly a pest.
