What Is Didanosine?
Didanosine is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults and children 2 weeks of age and older. Didanosine is always used in combination with other HIV medicines.
Didanosine belongs to a class (group) of HIV drugs called nucleoside reverse transcriptase inhibitor (NRTIs). NRTIs block an HIV enzyme called reverse transcriptase. (An enzyme is a protein that starts or increases the speed of a chemical reaction.) By blocking reverse transcriptase, NRTIs prevent HIV from multiplying and can reduce the amount of HIV in the body.
HIV medicines can't cure HIV/AIDS, but taking a combination of HIV medicines (called an HIV regimen) every day helps people with HIV live longer, healthier lives. HIV medicines also reduce the risk of HIV transmission. If you are taking HIV medicines, including didanosine, don't cut down on, skip, or stop taking them unless your health care provider tells you to.
