Bridging Prescription

A bridging prescription is hormones prescribed by a GP or family doctor to someone waiting for a gender clinic, to "bridge" the gap until the specialist sees them. The term is used mostly in the UK, where waits for a first gender clinic appointment run to years.

Where you'll meet it

In UK discussions of NHS gender services, and in the conversation with a GP when you are on a long waiting list. Often it comes up because someone has already started hormones on their own, bought online or from a friend, and a bridging prescription replaces self-sourced medicine with a prescribed one and proper blood tests.

What it is for

It is a harm-reduction measure, not a fast track. General Medical Council guidance allows a GP to bridge in limited circumstances: broadly, when someone is already taking hormones without supervision, or is at real risk of doing so, and has been referred to a specialist service. The point is that unmonitored hormones, often at doses and in forms nobody would prescribe, are more dangerous than prescribed ones with bloods. The position has shifted over the years, and practice policies vary, so the current guidance and your practice's stance are both worth asking about.

Who decides

The GP. Some are willing, often with advice from a specialist, an NHS gender service or a private clinic; many are not, because prescribing gender-affirming hormones is outside what they are used to and they feel exposed doing it alone. Being refused is common and is not the end of the conversation. Ask for the reason in writing, and ask whether another GP in the practice would consider it.

The usual conditions

Where a GP agrees, it tends to come with blood tests before starting and regularly afterwards, a conservative regimen using standard medicines (estradiol rather than anything bought as a contraceptive pill, for example), and an expectation that the gender clinic takes over when your appointment arrives. Some GPs want you to have a referral already in place; some want a letter from a specialist first.

How it differs from shared care

A bridging prescription is the GP acting before any specialist has seen you. Shared care is the GP prescribing on a specialist's recommendation, after assessment, whether that specialist is NHS or private. Both put the prescription on the NHS, where you pay the standard charge per item in England, a little under £10 each, and nothing in Scotland, Wales and Northern Ireland. Cost and insurance has the rest.

Common questions

It skips the waiting list. It does not. You stay on the list, and the gender clinic still does the assessment when your turn comes.

Admitting you self-medicate will count against you. A GP needs to know exactly what you take, from where and for how long, to keep you safe, and in practice that honesty is what makes a bridging prescription possible at all. It is also what gets your blood monitored even if the GP will not prescribe.

The GP has to agree. They do not. Guidance permits bridging; it does not require it.

What to bring and ask

Bring a list of exactly what you take, the form, how often and where it comes from, plus any blood results you have had done privately. Ask whether the practice will bridge, whether it will at least do blood tests on the hormones you already take, and what it would need from a specialist to agree. Gender clinics covers the waits, private options and shared care; blood tests covers what should be checked either way.
