Why you should take your ARVs properly

Close to 900 000 people in Zimbabwe are on anti-retroviral therapy (ART). It is important to take medicines religiously, as prescribed by health personnel to avoid treatment failure.

The available anti-HIV drugs cannot cure HIV. However, treatment with a combination of these drugs can reduce the amount of HIV in your blood (your viral load) and prevent HIV from reproducing in your body. This allows your immune system to stay strong and fight off infections and other illnesses.

There is very good evidence that the HIV treatment available today will work against the virus in the long-term and keep your viral load undetectable indefinitely.

However, for this to be the case, it is very important to take your HIV treatment properly. Adherence is the most important factor under your control in the success of your HIV treatment.

Not taking your HIV treatment properly can mean that the levels of the drugs in your blood are not high enough to properly fight HIV. If this happens, your HIV will be able to reproduce. The strains of HIV that reproduce when you are taking HIV treatment can develop resistance to the drugs you are taking. Resistance can mean that your HIV treatment will not work effectively.

Your treatment not working is likely to mean that your viral load will increase and your CD4 cell count, an important indicator of the health of your immune system, will fall. This situation increases your chances of becoming ill because of HIV.

If your viral load increases to detectable levels, you may need to change your HIV treatment. This new treatment might be more difficult to take than the combination you were taking before and could involve a risk of more, or new, side-effects.

Your HIV may also become resistant to drugs similar to those you are currently taking (that is, in the same “class” of drugs). This is called cross-resistance and the risk varies between different classes of HIV drugs.

When taken properly, HIV treatment can also lower viral load in genital fluids. This can greatly reduce the risk of HIV transmission during sex. Using condoms will further reduce the risk, as well as protecting you and your partner from other sexually transmitted infections and preventing unplanned pregnancy.

Bear in mind that having another sexually transmitted infection (STI), such as chlamydia or gonorrhoea, can also increase HIV viral load in genital fluids, possibly making you more infectious.

A consequence of not taking your HIV treatment properly can be that the amount of virus in your genital fluids increases, therefore increasing the risk of passing on HIV to your sexual partner(s). The HIV you pass on may also be resistant to one or more anti-HIV drugs.

If you are on ART, ensure that you visit your nearest health centre for routine monitoring to check whether you are responding well to treatment.
