I've been prescribed 75mcg Levo but my local pharmacy says they can only get Teva. They say even if the GP specifies a brand they wouldn't be able to order it. I've called a few pharmacies locally and they say they just order Levothyroxine and get what they are given. How can I get round this as Teva makes me feel ill? Which other manufacturers can I realistically get? And how?! My GP isn't overly helpful so I need to make it easy for him. I don't really want to take 50 + 25 as I'm rubbish at taking pills so want to only take one. Thanks

75mcg Levothyroxine pills not TEVA!



until recently Teva was the ONLY brand that made 75mcg tablets
Now there’s Vencamil in 75mcg
Also Crescent available in 75mcg
Vencamil is lactose free and mannitol free. originally only available as 100mcg only, but 25mcg, 50mcg and 75mcg tablets became available Sept 2024
Prior to March 2023 Vencamil was called Aristo
Vencamil often very well tolerated/best option for many people

Excipients: lactose monohydrate, maize starch, croscarmellose sodium, gelatin and magnesium stearate.

I don't really want to take 50 + 25 as I'm rubbish at taking pills so want to only take one.
How long have you been on just 75mcg
That’s only one step up from standard starter dose, unless very petite, most people will eventually need at least 100mcg daily
Get FULL thyroid and vitamin testing 2-3 months after each increase
And again 2-3 months later
you need TSH, FT4 and FT3 tested
Also both TPO and TG thyroid antibodies tested at least once to see if your hypothyroidism is autoimmune
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
Post all about what time of day to test
healthunlocked.com/thyroidu...
Testing options and includes money off codes for private testing

If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test
If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal
I’ve done all that. I went up to 100mcg but it was making me anxious and have heart palpitations. I’m sub clinical. Back down to 75mcg even though that wasn’t enough (TSH was 3.5 on 75mcg). There is an issue that my GP doesn’t think I should be on medication so doesn’t want to help. I saw an endocrinologist privately in the summer who supported me at the time. He is away but his secretary said he said to reduce to 75mcg now. Most of my vitamins are low but he said that shouldn’t matter. He told her my symptoms aren’t related to my thyroid. On 100mcg my TSH was 0.1. T4 was 150% through the range. T3 was 14% through the range. I asked if I was having a problem converting from T4 to T3. He said the T3 test isn’t reliable and I should reduce to 75mcg. In the last few months everything has ached. I’m really stiff. I can’t lie down without it hurting. My shoulder hurts so badly I ended up at minor injuries but they were interested. There have been nights where I have been awake all night as I can’t sleep. I also have psoriatic arthritis so it could be that but I can’t get an appointment with my rheumatologist till June. My GP told me to speak to my endocrinologist and put the phone down. I feel like no one will help right now. My son is freaking out because I can barely move and he thinks there’s something really wrong with me. I’m beginning to wonder the same.
That’s terrible to put the phone down on you. I think if you get your vitamins at an optimal level you will feel better Your vitamins need to be optimal so the Levothyroxine will work. I hope this helps you.
So your hypothyroidism is autoimmune
It’s absolutely ESSENTIAL to test and maintain GOOD vitamin levels for good conversion of Ft4 to Ft3
So first steps are to improve vitamin levels
Most of my vitamins are low
How long ago were these tests done
Please add actual results and ranges
Exactly what vitamin supplements are you taking
You may need to increase dose in smaller steps
Eg 75mcg and 100mcg alternate days
or 100mcg 2 days a week initially
Get a weekly pill dispenser so it’s easy to remember
Retest thyroid levels 6-8 weeks after each dose change or brand change in Levo
Test vitamin D twice year
Test folate, ferritin and B12 at least annually, more frequently if low and working on improving
Aiming for
Vitamin D at least over 80nmol
Folate at top of range
Serum B12 over 500
Active B12 over 70
Ferritin at least over 80
My shoulder hurts so badly I ended up at minor injuries
Sounds like frozen shoulder?
Very common with thyroid
See physio for graded exercise program
my antibodies were negative but the Endo said he’s sure it’s autoimmune as I also have psoriatic arthritis. I’ve also included results from July before I started on Levo.
So B12, folate very low
Vitamin D fairly low

Suggest you start back on vitamin supplements starting with B12
With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a separate B12 supplement
A week later add a separate vitamin B Complex
Then once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.
If Vegetarian or vegan likely to need ongoing separate B12 few times a week

Low folate
supplementing a good quality daily vitamin B complex, one with folate in (not folic acid)
This can help keep all B vitamins in balance and will help improve B12 levels too
Difference between folate and folic acid

B vitamins best taken after breakfast
Igennus B complex popular option. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose and may need 2 per day and/or may need separate methyl folate couple times a week
Post discussing different B complex
healthunlocked.com/thyroidu...
Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule) Thorne can be difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before ALL BLOOD TESTS , as biotin can falsely affect test results
endocrinenews.endocrine.org...
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12 if last test result serum B12 was below 500 or active B12 (private test) under 70
no ferritin result?
Once you get vitamin D result
Improve and then maintain at least over 80nmol and 100-125nmol may be better
around 80nmol or 100nmol by self supplementing may be better
pubmed.ncbi.nlm.nih.gov/218...
vitamindsociety.org/pdf/Vit...
Once you Improve level, very likely you will need on going maintenance dose to keep it there.
Test twice yearly when supplementing
Can test via NHS private testing service
Vitamin D mouth spray by Better You is very effective as it avoids poor gut function.
There’s a version made that also contains vitamin K2 Mk7.
One spray = 1000iu

It’s trial and error what dose we need, with thyroid issues we frequently need higher dose than average

Agreed
Have you had BOTH TPO and TG antibodies tested
Significant minority of Hashimoto’s patients only have high TG antibodies (thyroglobulin)
NHS only tests TG antibodies if TPO are high
20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis

Gluten intolerance is often a hidden issue too.
Request coeliac blood test BEFORE considering trial on strictly gluten free diet
Thanks. I’m taking supplements now so let’s see. There’s no ferritin because I forgot to ask for that one when I was with my GP. He didn’t want to do the ones I had. He said Vit D isn’t relevant so I had to insist. I’ve asked for ferritin but I’m not sure he will be willing to do them all again and I can’t afford to keep buying tests privately. So I’m just hoping things will improve with what I’m doing. If not I have no idea where to go next.
I started taking vitamin supplements a week ago. No improvement yet…
Exactly what are you taking
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
(Time gap doesn't apply to Vitamin D mouth spray)
I take my Levothyroxine first thing. Vitamins (wellwomsn gummies for all round (I can’t take big pills or capsules) , also have Vit D & K2, Vit b12) at lunchtime. I’ve bought some folate too. I take sulfasalazine for my arthritis at lunch and dinner.
How much vitamin D
You need a good quality vitamin B complex, rather than just folate
Igennus B complex popular option. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose and may need 2 per day and/or may need separate folate couple times a week

The pharmacist go on what’s available and within the cost envelope as govt hasn’t increased levies. You said you only wanted one pill but you may need to flexible to get the right dose for you. Could you ask your GP for alternative75mcg and improve your vitamins as slow dragon said. If that doesn’t help as much as you need, slowly increase t4 to 87.5 with a pill cutter on a 25mcg tab to help body adjust to higher dose without such overt symptoms. maybe on alternate days - and see how you feel.
I had exactly the same experience. It took persistence and insistence and trying difference pharmacies, but I finally got one to source Vencamil. If you can get the brand you want in 50 + 25, you might want to do that and try again for 75 next time.
Hi Flower7777 I've found my local Boots pharmacy are quite good at sourcing the right brands of levo for you and I always check what's in the bag before leaving the shop . You may need to insist if you have a bad reaction to a particular brand as that is quite serious. I take 50 + 25. It's no big deal and also allows for flexibility as I alternate with a 50 + 12.5. in my current bid to find my ideal dose. I've also found optimal vitamin levels are crucially important if you are to get the best results from the levo. There's a lot to learn but there's lots of advice on this site too.
