Ask about Cariban and you will hear two things that used to be true and are not any more. That you need a consultant to get it, and that it costs a fortune. You will also hear a third thing that has never quite been true: that it is free now.
The real answer is one word, and it is not "free". It is reimbursed. Those are different things, and the difference is exactly what you hand over at the counter.
This guide is about the paperwork and the money. Whether Cariban is right for you, what it does, and what else might help are questions for your GP or your maternity team, and the HSE page on hyperemesis gravidarum is the place to read about the condition itself.
The short version
- Is it free?
- No. It is reimbursed under the community drug schemes, which is not the same thing
- Do you need a consultant?
- No. Since 1 August 2024 it is not restricted to consultant prescribing
- Who can prescribe it
- Any prescriber, on a valid prescription. That includes your GP
- With a medical card
- Covered under the GMS scheme, subject to the usual prescription charge
- Without a medical card
- It counts towards your Drugs Payment Scheme total
- The DPS cap
- €80 a month for you and your family, for all approved prescribed medicines together
- The thing to do first
- Register for the DPS before you need it, not at the counter
The consultant rule is gone, and a lot of advice has not caught up
For a while, getting Cariban meant a managed access arrangement: the medicine was supplied as an unlicensed product under a special scheme, and access was restricted. That is where the advice to "wait for your consultant" comes from, and it was correct at the time.
It changed on 1 August 2024. The HSE's own circular to pharmacists says the licensed product was approved for reimbursement under the community drug schemes, that from that date it can be claimed in the normal way on foot of a valid prescription from a prescriber, and, in plain terms, that there is no managed access arrangement and that it is not restricted to consultant prescribing or initiation.
So the practical answer to "do I have to see a consultant first" is no. Your GP can prescribe it. If you are still being told to wait for a hospital appointment before anyone will write the prescription, that is the old arrangement, and the circular below is the document that says so.
Reimbursed is not free, and the difference is which scheme you are on
Being on the reimbursement list means the state pays the pharmacy for it under the community drug schemes. It does not mean you walk out having paid nothing. What you pay depends on which scheme covers you, and there are two.
If you have a medical card, Cariban is covered under the GMS scheme like any other prescribed medicine, and the usual prescription charge applies.
If you do not have a medical card, it goes through the Drugs Payment Scheme. Under the DPS you and your family pay a maximum of €80 each month for all approved prescribed medicines together, not per item and not per person. If your household already spends up to that cap in a month, adding Cariban does not increase what you pay at all. If it does not, Cariban counts towards it.
That is the whole reason the same medicine gets described as both crushingly expensive and nearly free by two people in the same conversation. They are on different schemes, or one of them had not registered for the DPS yet.
Register for the Drugs Payment Scheme before you need it. The cap only protects you once you are registered and the pharmacy has your card, and the moment you find out you need it is the worst moment to be filling in a form. It costs nothing to hold and it covers your whole household for everything, not just this. If you are pregnant and not registered, this is a twenty-minute job worth doing this week.
One pharmacy a month, if you can
A detail that catches people out and has nothing to do with Cariban specifically. The DPS cap is applied by the pharmacy, so Citizens Information advises using the same pharmacy within a month. If you split your prescriptions across two or more pharmacies you can end up paying more than the cap, because no single pharmacy sees your full monthly total.
You can claim a refund for the amount over the threshold, but that is a form afterwards rather than money you keep in the first place.
Who decides what
Your prescriber, which can be your GP, decides whether to prescribe it. The HSE Primary Care Reimbursement Service runs the reimbursement lists and the community drug schemes, and sets the rules this page describes. Your pharmacy applies the cap and claims the reimbursement. The HSE decides medical card eligibility.
We decide none of it and we are not a clinical service. This guide sets out what the official documents say about who pays, so that the money question does not stand between you and a conversation with your GP.
