Your Guide to HIV Treatment

Hypersensitivity

You may be allergic, or hypersensitive, to certain drugs. For example, some people are hypersensitive to abacavir (Ziagen, ABC, also found in Kivexa, Trizivir and Triumeq). A simple blood test, done before you start treatment, can determine whether you’re likely to have a potentially dangerous reaction to abacavir. If your test result is positive, you can cross that drug off your list of choices. If your test result is negative, a reaction is still possible but the risk is low.

Ask your doctor about the signs of a hypersensitivity reaction so that you can seek medical help should you have such a reaction to abacavir or another HIV drug.
