General ideas or principles

Three general ideas increase the chance of your next treatment working.

  1. Using drugs from a new class.
  2. Using drugs from classes you have used before but did not develop resistance to.
  3. Using more, rather than fewer drugs, may have an added benefit.

Treatment guidelines also outline ways to choose new drugs. See:

It will also depend on the reason that your previous combination failed and on the results of other tests.

Resistance tests will help pick meds that may work, even when you have some resistance.
