Treatment

While there's no cure for HIV, there are very effective treatments that enable most people with the virus to live a long and healthy life.

Emergency HIV drugs

If you think you've been exposed to the virus, post-exposure prophylaxis (PEP) medication may stop you becoming infected.

PEP must be started within 72 hours of coming into contact with the virus for it to be effective. It's only recommended following higher risk exposure, particularly where the sexual partner is known to be positive.

PEP involves taking HIV treatment every day for 1 month. It may cause some side effects.

You should be able to get PEP from:

  • sexual health clinics or genitourinary medicine (GUM) clinics
  • hospitals – usually accident and emergency (A&E) departments

If you already have HIV, try your HIV clinic if the PEP is for someone you've had sex with.

If you test positive

If you're diagnosed with HIV, you'll have regular blood tests to monitor the progress of the HIV infection before starting treatment.

Two important blood tests are:

  • HIV viral load test – a blood test that monitors the amount of HIV virus in your blood
  • CD4 lymphocyte cell count – which measures how the HIV has affected your immune system

Treatment can be started at any point following your diagnosis, depending on your circumstances and in consultation with your HIV doctor.

Antiretroviral drugs

HIV is treated with antiretroviral medications, which work by stopping the virus replicating in the body. This allows the immune system to repair itself and prevent further damage.

A combination of HIV drugs is used because HIV can quickly adapt and become resistant.

Some HIV treatments have been combined into a single pill, known as a fixed dose combination, although these often cost more to prescribe.

Usually, people who have just been diagnosed with HIV take between 1 and 4 pills a day.

Different combinations of HIV medicines work for different people, so the medicine you take will be individual to you.

The amount of HIV virus in your blood (viral load) is measured to see how well treatment is working. Once it can no longer be measured it's known as undetectable. Most people taking daily HIV treatment reach an undetectable viral load within 6 months of starting treatment.

Many of the medicines used to treat HIV can interact with other medications prescribed by your GP or bought over-the-counter.

These include some nasal sprays and inhalers, herbal remedies like St John's wort, as well as some recreational drugs. Always check with your HIV clinic staff or your GP before taking any other medicines.
