- It’s better to start HIV treatment sooner, rather than later.
- Treatment will reduce the risk of HIV transmission, prevent illnesses and extend your life.
- A range of different antiretroviral drugs are available.
Everyone who has diagnosed HIV is recommended to take HIV treatment. It is better for your health to begin HIV treatment sooner, rather than later.
Anti-HIV drugs work by lowering the amount of HIV in the blood (viral load). The aim of HIV treatment is an undetectable viral load. This means that the amount of HIV in a blood sample is so low that it cannot be detected using a standard test. Reducing the amount of HIV in your blood allows your immune system (measured by your CD4 cell count) to strengthen. The higher your CD4 cell count, the lower your risk of becoming ill because of HIV (and possibly some other serious illnesses as well).
You should discuss with your doctor the best time for you to start HIV treatment. There are a number of factors you might want to consider, including:
- The benefits of starting treatment now.
- The potential risks if you delay starting treatment.
- Are you ready to start treatment now?
- Are there other factors in your life that affect your ability to start taking HIV treatment?
There may be other things which are relevant to your treatment and care and you may have other questions. It's a good idea to take some time to think about these before you go to an appointment at your clinic.
When to start treatment
The sooner you start to take HIV treatment, the sooner you can benefit from it. HIV treatment guidelines, both in the UK and elsewhere in the world, recommend that all people with HIV should take HIV treatment, regardless of their CD4 count.
You can start taking HIV treatment as soon as you feel ready.
In 2015 a large, well-conducted study demonstrated that there are advantages to starting treatment as soon as possible, even with high CD4 cell counts. The study clearly demonstrated that starting HIV treatment earlier is beneficial and reduces the risk of most serious illnesses. While people sometimes worry about the side-effects of anti-HIV drugs, the study also showed that people who began HIV treatment earlier had a better quality of life than people who waited.
Another important benefit of starting treatment is that it usually suppresses the amount of HIV in your body fluids to an ‘undetectable’ level. Having an undetectable viral load means that there is not enough HIV in your body fluids to pass HIV on during sex. In other words, you are not infectious.
Other research has shown that with HIV treatment, many people living with HIV can have a relatively normal lifespan.
If your CD4 cell count is below 200, it is especially important that you begin HIV treatment as soon as possible. The lower your CD4 cell count, the greater the risk of infections and HIV making you ill.
Similarly, if you have caught HIV very recently – within the past three months – your doctor is likely to encourage you to start treatment without delay. This is because some people can become seriously ill soon after infection. Starting treatment very soon after infection reduces the chances of illness. It also gives you the best chance of having a normal immune system while living with HIV.
While the medical case for starting treatment as soon as possible is clear cut for most people, the decision to start treatment rests with the person living with HIV. Before starting treatment, it’s important that you understand how it works and what it involves. You may need a little time before you feel ready to start.
Which anti-HIV drugs to start with
Standard treatment for people starting HIV treatment for the first time is a combination of three different drugs. Anti-HIV drugs belong to different classes depending on the way they work against HIV. The main classes of anti-HIV drug are nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), boosted protease inhibitors and integrase inhibitors.
In the UK, standards for HIV treatment and care are set by the British HIV Association (BHIVA), the professional association for HIV doctors and other healthcare professionals. Their guidelines for HIV treatment are reviewed regularly and their current recommendations for which anti-HIV drugs to use are summarised on another page.
