Teva medication

[Pfhh]

I saw the concern about Teva adding mannitol to levothyroxine on this site 5 yrs ago. My new medication from Lloyds direct has been changed to Teva without being informed. I have also recently been informed I have ibs. I am not prepared to accept E-numbers or risk being ill due to the change. Has anyone recently had the same and can you offer any help.

many thanks

look at the fillers in Teva, mannitol, you can check online. Boots the chemist has it on my records no Teva. Also noted at the Doctors. Ended up doing a yellow card report. Went back to my old make and had no problems. Hope this might help.

Thanks for this, yes I did see mannitol. An E number I do not need. Contacted Lloyds, so awaiting response👍😁

You cannot avoid "E-numbers" in levothyroxine products. All of them contain at least one substance that has an E-number assigned. (All UK tablets contain E470b - Magnesium stearate or E460 - Microcrystalline Cellulose. All UK oral solutions contain E422 - Glycerol.)

The problem with Teva is that some members cannot tolerate it. While other members prefer it to any other that they have tried.

Thanks, it’s the Mannitol I don’t need, 1 less to worry about👍

What dose do you need? Vencamil possibly has the least 'extras' but only comes in 100mcg at the moment

[Pfhh in reply to TiggerMe]

Thanks for the info, 100/125 twice a week but don’t think I need this extra as they are keeping me at top end of normal. Will ask the Gp to change as due review few months.

Many people find Levothyroxine brands are not interchangeable.

Most easily available (and often most easily tolerated) are Mercury Pharma or Accord

Mercury Pharma make 25mcg, 50mcg and 100mcg tablets 

Mercury Pharma also boxed as Eltroxin. Both often listed by company name on pharmacy database - Advanz

Accord only make 50mcg and 100mcg tablets. Accord is also boxed as Almus via Boots, 

Wockhardt is very well tolerated, but only available in 25mcg tablets. Some people remain on Wockhardt, taking their daily dose as a number of tablets 

Lactose free brands - currently Teva or Vencamil only

Teva makes 25mcg, 50mcg, 75mcg and 100mcg

Many patients do NOT get on well with Teva brand of Levothyroxine.

Teva is lactose free.But Teva contains mannitol as a filler instead of lactose, which seems to be possible cause of problems. Mannitol seems to upset many people, it changes gut biome 

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

But for some people (usually if lactose intolerant, Teva is by far the best option)

Aristo (currently 100mcg only) is lactose free and mannitol free.

March 2023 - Aristo now called Vencamil

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.

Government guidelines for GP in support of patients if you find it difficult/impossible to change brands

gov.uk/drug-safety-update/l...

If a patient reports persistent symptoms when switching between different levothyroxine tablet formulations, consider consistently prescribing a specific product known to be well tolerated by the patient.

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).
