HRT Shortages in the UK
Why HRT supply issues happen, current UK availability and safe swaps if your prescription is unavailable.
When your usual HRT is out of stock, there are almost always clinically equivalent alternatives. This guide explains why UK shortages happen, what to check with your pharmacist, and which switches your specialist can safely recommend.
UK HRT supply has stabilised considerably since the acute 2022 crisis, but intermittent gaps in specific brands and doses still occur every few months. The important message is that a shortage of one product is almost never a shortage of the treatment — there is nearly always a clinically equivalent alternative you can safely switch to, and a specialist can make that change quickly and confidently.
Why shortages happen
- Global demand for transdermal oestrogen (gels, patches, sprays) has grown much faster than manufacturing capacity — the UK has one of the highest prescribing rates in the world.
- Manufacturing issues at a single plant can affect supply for months because only a handful of factories worldwide make each product.
- Brexit-related regulatory changes, MHRA relicensing and packaging requirements all add friction to the supply chain.
- Panic buying during previous shortages worsened the picture — steady, predictable prescribing helps everyone.
What to do if your HRT is out of stock
- Ask your pharmacist to check regional wholesalers first — brands rotate in and out on a weekly basis and stock can appear overnight.
- The Department of Health and Social Care issues Serious Shortage Protocols (SSPs) allowing pharmacists to substitute clinically equivalent products without a new prescription — check the current SSP list.
- Contact the prescriber (NHS GP or private specialist) for an equivalent-dose script if no SSP is in force.
- Larger independent pharmacies and specialist menopause pharmacies often have stock when high-street chains do not.
Safe equivalent swaps between oestrogen products
- Oestrogel 2 pumps daily ≈ Sandrena 1mg sachet daily ≈ Estradot 50 patch twice weekly — all deliver roughly the same systemic oestradiol dose.
- Lenzetto spray 2 sprays ≈ Oestrogel 1 pump — useful when gels are short.
- Evorel patches, Estradot patches and Estraderm MX are largely interchangeable at matched strengths.
- Never crudely double a dose to compensate for a missed brand — the delivery profiles differ.
Progestogen supply
- Utrogestan 100mg (micronised progesterone) is now supplied by multiple UK manufacturers and rarely runs short.
- If Utrogestan is genuinely unavailable, dydrogesterone or a Mirena coil are body-safe alternatives — discuss with your prescriber.
What not to do
- Don't stop HRT abruptly — vasomotor symptoms rebound within days and bone-protective benefit is lost.
- Don't buy HRT online from unregulated overseas pharmacies — counterfeit oestradiol has been documented.
- Don't share prescriptions or halve a partner's supply — dosing is individual.
Key takeaway
Shortages of a specific brand are almost never shortages of the treatment — clinically equivalent alternatives exist for every UK HRT preparation.
How Dr Awal approaches this in clinic
Every consultation starts with your full story — symptoms, cycle, medical history, family history and what you've already tried. From there we look at whether hormonal treatment, non-hormonal options, lifestyle changes or a combination will give you the best result, and we tailor the plan to your age, risk factors and preferences.
- A detailed 60 minute first appointment — no rushed 10-minute slots.
- Evidence-based recommendations aligned with NICE NG23 and BMS guidance.
- Body-identical HRT considered first-line where appropriate.
- Shared-care letters sent to your NHS GP so treatment can continue affordably.
- Follow-up at 3 months to fine-tune your regimen and address side effects.
- Ongoing annual reviews so your plan evolves with you.
Common questions we hear about this
Do I need to be at a certain age to be seen?
No. We see women in early perimenopause (often late 30s and 40s), through post-menopause and beyond. Age alone doesn't decide whether treatment is right — symptoms, health history and goals do.
Will my GP continue the prescription?
In most cases yes. After your consultation we send a detailed shared-care letter with the diagnosis, treatment plan and rationale so your NHS GP can prescribe on the NHS. Not every practice accepts shared care — we'll discuss this in your appointment.
What if I've tried HRT before and it didn't suit me?
Very common — often the type, dose or route wasn't right rather than HRT itself. We review what you've tried, why it didn't work, and adjust accordingly. Many women who thought HRT wasn't for them do well on a different preparation.
How long will I need to stay on treatment?
There is no set upper time limit for HRT. Current BMS and NICE guidance supports continuing HRT for as long as the benefits outweigh the risks for you personally. We review this together every year so you stay in control of the decision.
Where do you see patients?
All consultations at Pause and Co Healthcare are conducted securely via video, allowing us to support patients anywhere in the UK. Prescriptions and shared care arrangements are managed in the same way, regardless of your location.
