How to choose new drugs

Several general points increase the chance of your next treatment working.

If you can use drugs from a new class.
If you can use drugs from classes you have used before but not developed resistance to (i.e. switch while your viral load is still low).
If you use more, rather than fewer drugs, you may get added benefit from all of them together.

Trial results, even for new drugs, are the best place to find information to predict how well a new drug will work for you. These results should also include information about drug resistance mutations.

Decisions relating to your treatment should always be taken in consultation with your doctor. Information in this guide is intended to support those discussions.
