Cross-resistance
Once resistance to one anti-HIV drug has developed, this may mean that your HIV is also resistant to other, similar anti-HIV drugs you haven’t yet taken. This is called cross-resistance.
Cross-resistance can affect all the currently available anti-HIV drugs to some extent. However, cross-resistance isn’t inevitable if you develop resistance to one drug, and the use of resistance tests will help you and your HIV doctor select the anti-HIV drugs that are likely to be most effective against your virus if resistance does develop.
