Adherence is the term that is used to describe taking your medicines properly.

If you take your medicines properly then they are more likely to work.

Taking your HIV treatment properly is very important. If you don’t this can mean that HIV has a chance to change and become resistant to the anti-HIV drugs you are taking. It might also mean that your HIV becomes resistant to HIV drugs similar to the ones you are taking.

Taking your HIV drugs properly means:

**Taking all the doses of your drugs. If you miss doses, this gives HIV a chance to become resistant

**Taking your doses at the right time. If you take your medicine too early or too late it can be as bad as missing does completely.

**Making sure you take your medicines in the right way. Some medicines need to be taken with food to work, but other need to be taken on an empty stomach. If you take your pills in the wrong way it can mean that you don’t absorb enough of them to fight HIV, risking resistance.

**Making sure don’t take other drugs or medicines that interfere with your body’s ability to process your HIV treatment. Always tell your HIV doctor about any other medicines you are taking. This includes ones another doctor has given you or that you have bought from a chemist. Also tell your doctor about any recreational drugs you are taking. Interactions between medicines or drugs can mean that not enough of one medicine reaches your blood to help make you better. Or it can mean that you get too much of a medicine or drug, and that can be dangerous.

Every time your doctor prescribes medicines to you they or the pharmacist should tell you what you need to do to take it properly. They should also give you written information to take away about your treatment explaining how you take it.

Ask questions if you are not sure about anything.

Taking anti-HIV treatment is a long-term commitment. It is therefore important that the treatment that you take fits in with the way you live your life. Don’t be frightened to tell your doctor if you think you’ll find a treatment difficult to take properly. There might be alternatives.

If you are taking anti-HIV treatment for the first time, then there is a good chance that your treatment will consist of now more than a few pills taken once or twice a day. And treatment is now available that consists of just one pill, once a day.

Most people will forget to take a dose of their medicine at some time. Don’t worry too much if this happens occasionally. But talk to your doctor if you are missing a lot of your doses. It might be possible to find a treatment that you find easier to take.

There are other things you can do to help you take your medicines properly. For example, some people keep a diary. For other people, pill boxes help and these are available from your HIV clinic and help you keep track of your doses.
