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. Didanosine is always used in combination with other anti-HIV medicines.

Didanosine is a type of anti-HIV medicine called a nucleoside reverse transcriptase inhibitor (NRTI). NRTIs work by blocking HIV reverse transcriptase, an HIV enzyme. This prevents HIV from replicating and lowers the amount of HIV in the blood.

Didanosine does not cure HIV/AIDS. It is not known if didanosine reduces the risk of passing HIV to other people.
