Key points

  • For people taking HIV treatment, the intrauterine device (IUD) is the recommended method of emergency contraception.
  • People taking some anti-HIV drugs need to take a double dose of the ‘morning-after pill’.
  • An abortion is an option if you decide you do not want to go through with a pregnancy.

This page is for people living with HIV who want information about emergency contraception and unwanted pregnancy. Please note that some of the services mentioned here are specific to the UK.

There may be a time when your normal form of contraception fails – you may forget to take your contraceptive pill or a condom could break. Sometimes sex may happen when you aren’t using any contraception at all.

Emergency contraception can be used in the days after unprotected sex to prevent an unwanted pregnancy. (This is not the same as terminating a pregnancy, also called an abortion.) There are two methods of emergency contraception. 

The emergency contraceptive pill (Levonelle). Often called the ‘morning-after pill’, this works best when it is taken soon after unprotected sex – preferably within 24 hours, but certainly within 72 hours (three days) of having sex.

If you are on HIV treatment, it is important that the person who provides you with the pill knows this. Several anti-HIV drugs interfere with the way the pill works. If you are taking one or more of these anti-HIV drugs, you will need to take twice the normal dose of the emergency contraceptive pill. 

The pill is available free from HIV clinics, sexual health clinics, contraceptive clinics, GPs, and some accident and emergency departments in hospitals. It is available to buy from most pharmacies; a single dose costs around £30-35 (£60-70 for a double dose). Some pharmacies provide them free of charge. The pharmacist may not sell Levonelle to you if they know you are on HIV treatment and will recommend you see a doctor to have it prescribed.

There is a second emergency contraceptive pill called ellaOne, which needs to be taken within five days of having sex. This pill is not effective if you are on a number of medications, including some anti-HIV drugs. You should seek the advice of an HIV pharmacist before taking ellaOne, which usually has to be prescribed by a doctor.

The intrauterine device (IUD). It is a more reliable method, especially if you are taking HIV treatment. This is the same device that is used for normal contraceptive use. To work as emergency contraception, it needs to be fitted within five days of either unprotected sex or ovulation. It can be removed after your next period, or you could leave it in to work as contraception in the future.

The IUD must be fitted by a specially trained doctor or nurse. The quickest place to find someone like this will be a contraceptive clinic, but the IUD may also be available at sexual health clinicsGPs and HIV clinics. You will not have to pay.

Find out more about both of these emergency contraception options on the NHS website.

Unwanted pregnancy

There may be a time when you find you are pregnant and don’t want to be. This can be a difficult decision, but it is your choice whether or not you want to continue with the pregnancy.

Before you take any other action, it is important to confirm that you are pregnant. A pregnancy test is the most reliable way to do so. You will need to give a urine sample, which tests for the presence of a pregnancy hormone. You can take a test any time from the first day of your missed period, at: 

  • your GP surgery (free)
  • a family planning clinic (free)
  • a pharmacy – tested by a member of staff (there may be a charge)
  • a pharmacy – buy a test to use at home.

You can find out more about taking a pregnancy test on the NHS Choices website. 

If the test confirms you are pregnant, you may want to talk to someone about your next steps. Staff at a contraceptive clinic, a sexual health clinic, your HIV clinic or your GP surgery can help you think through your options. You can find information on unplanned pregnancies on the Sexwise website. You can also call the National Sexual Health Helpline, provided by Public Health England, on 0300 123 7123 (Monday to Friday, 9am to 8pm; weekends 11am to 4pm).

Other organisations can help with advice and support, such as:

  • MSI Reproductive Choices (formerly Marie Stopes) (helpline: 0345 300 8090, www.msichoices.org.uk)
  • British Pregnancy Advisory Service (BPAS) (helpline: 03457 30 40 30, www.bpas.org)
  • National Unplanned Pregnancy Advisory Service (NUPAS) (helpline 0333 004 6666, www.nupas.co.uk).

Young people under 25 can get support, information and advice about their options from Brook (www.brook.org.uk). You can find a Brook service local to you or use their 24/7 Q&A tool.

Abortion (termination of pregnancy)

If you are pregnant and do not want to continue the pregnancy, you may consider having an abortion. Abortion is legal in England, Wales and Scotland up to 24 weeks (five months). After this, it is only allowed in exceptional circumstances.

There are two main techniques used to end a pregnancy in the first three months. These are more straightforward than if an abortion happens later on. (Other, more complex methods are used for later abortions.) 

‘Medical’ abortion: Taking one tablet one day, and different tablets up to two days later. The pregnancy will end after a few hours and may feel like a heavy period.

‘Surgical’ abortion: Most commonly, you are given an anaesthetic and a tube is placed through the vagina to the womb for a procedure called vacuum aspiration, also known as the ‘suction’ method.

Both techniques are as safe and effective for people with HIV as they are for other people and are carried out in the same ways. You won’t usually need to stay in hospital overnight for either of them.

Your GP, a doctor at a contraceptive clinic or your HIV doctor can make an appointment for you at a specialist clinic. The service will be free.



In relation to sex, a term previously used to describe sex without condoms. However, we now know that protection from HIV can be achieved by taking PrEP or the HIV-positive partner having an undetectable viral load, without condoms being required. The term has fallen out of favour due to its ambiguity.


How well something works (in real life conditions). See also 'efficacy'.


A patient’s agreement to take a test or a treatment. In medical ethics, an adult who has mental capacity always has the right to refuse. 


Studies aim to give information that will be applicable to a large group of people (e.g. adults with diagnosed HIV in the UK). Because it is impractical to conduct a study with such a large group, only a sub-group (a sample) takes part in a study. This isn’t a problem as long as the characteristics of the sample are similar to those of the wider group (e.g. in terms of age, gender, CD4 count and years since diagnosis).


A chemical messenger which stimulates or suppresses cell and tissue activity. Hormones control most bodily functions, from simple basic needs like hunger to complex systems like reproduction, and even the emotions and mood.

Some of these clinics are run by charities such as BPAS or MSI Reproductive ChoicesNUPAS is a private provider. It’s possible to go directly to any of them, and in many cases, their services will be paid for by the NHS. But you may be asked to pay if you are not eligible for this treatment on the NHS. Costs start at around £500 but can be considerably more depending on how many weeks pregnant you are and what type of termination you have.

Your first visit to the clinic will be an opportunity to have your questions answered, for the doctor to find out about health issues that affect you, for tests and examinations, and for you to decide what you want to do. You’ll then be given an appointment to come back for the termination and asked to sign a consent form. You can find out more about the process of having an abortion on the NHS Choices and FPA websites. 

You can get pregnant again very soon after having an abortion, so it is important to use contraception if you still want to avoid pregnancy. Staff at the clinic can talk to you about your options.


Adoption could be a choice for you if you do not want to bring up a baby yourself, but you do not want to terminate the pregnancy (have an abortion). You would give the baby to new parents who will bring them up as their own. You will continue with the pregnancy and give birth, but you won't look after the baby, and you won't have legal rights or responsibilities regarding the child once the adoption is complete.

You would still need to take steps during your pregnancy and childbirth to prevent passing on HIV to the baby.

The organisation CoramBAAF has more information on adoption.
