Hi Reader

I want to share something that happened to me this week – because if it happened to me, it could easily be happening to you too.

You know that feeling when you've finally – finally – got something sorted with your health? When you've done the work, had the conversations, pushed through the awkwardness of advocating for yourself with your GP, and got something in place that actually helps?

And then, quietly, without anyone telling you, it gets undone.

That's what happened to me this week.

When the system changes things without warning

I went to collect my Levothyroxine prescription. As I always do, I checked what I'd been given at the counter – something I'd encourage every single one of you to do, always.

The Accord was there. But in place of my Wockhardt, I'd been given Teva.

For those of you who don't know my history with Teva – it makes me really unwell. My blood levels go haywire, my hypothyroid symptoms come flooding back, and it can take weeks to stabilise again. That's not a minor inconvenience. That's my life being derailed.

My GP had specified on my prescription which brands I needed, and which I should never be given. It's been on there for years. And I'd never had a problem.

Until now.

When I asked the pharmacist, she explained that since 1st April, an NHS system update has quietly removed all brand-specific notes that GPs had added to prescriptions. All of them. Wiped.

No letter. No warning. No "by the way."

I was lucky. My pharmacist is wonderful – she immediately ordered the right brand in and asked me to come back the next day. But as I drove home, all I could think about was how many of you don't have that.

How many of you have a pharmacy that's rushed, or indifferent, or just doesn't know you.

How many of you might not even realise the switch has happened until you're already feeling the effects and wondering what on earth is wrong.

That's the part that got me.

Why this matters so much for us

Here's what I really want you to understand, especially if you're newer to all of this.

Levothyroxine brands are not interchangeable for everyone.

Pharmacists may tell you they are. The information leaflet might suggest they are. But for many of us with hypothyroidism or Hashimoto's, the fillers and inactive ingredients in different brands can make a real and measurable difference to how we absorb the medication – and therefore how we feel.

Teva works well for some people. Perfectly well. And for others, it's the worst thing they can take. The same is true in reverse for every brand. It's not about which brand is "best." It's about finding the one that works for your body, and then fighting to stay on it.

Because here's what brand changes can do:

they can mimic a relapse.

They can make your symptoms come back – the fatigue, the brain fog, the weight gain, the low mood – and send you back to your GP convinced your levels have changed, when actually it's just that you've been quietly switched to a brand your body doesn't like.

That is exhausting. And it is so easy to miss.

What I'd like you to do

✅ Check your next prescription. Don't assume it'll be the same as last time. Look at the box. Check the brand name.

✅ If you have brand preferences, flag them at the pharmacy counter directly. Don't assume the notes are still on your prescription – because as of 1st April, they may well not be.

✅ Speak to your GP. I'm still looking into whether brand-specific notes can be re-added under the new system. I'll update you as soon as I know more. But it's worth having the conversation.

✅ If you don't yet know which brand works for you – start paying attention. Note how you feel in the weeks following each prescription collection, and whether anything changes when the brand changes.

The bigger picture

I think what this week reminded me – what it always reminds me – is that navigating a thyroid condition in the NHS requires a level of vigilance that we simply shouldn't have to carry.

It requires us to check things that should be checked for us.

To catch things that should never slip through.

To advocate, again and again, for basic consistency in our own care.

You are not being difficult when you ask for the right brand. You are not being a nuisance when you check what you've been given. You are doing what needs to be done, because too often, no one else is doing it for us.

Keep checking. Keep asking. And please do let me know in reply if this has happened to you too – I'd really like to get a sense of how widespread this is.
