Didanosine, also known as ddI, is a medication used in the treatment of HIV infection. It belongs to a class of drugs called nucleoside reverse transcriptase inhibitors (NRTIs), which work by blocking the enzyme needed for the virus to replicate. Didanosine is typically used in combination with other antiretroviral medications to effectively manage HIV and improve the immune system function.

It is important to take didanosine exactly as prescribed by your healthcare provider to ensure its effectiveness and minimize the risk of developing drug resistance. This medication is available in both tablet and powder form, and should be taken on an empty stomach at least 30 minutes before or 2 hours after a meal.

Like all medications, didanosine can cause side effects. Common side effects may include nausea, diarrhea, headache, and fatigue. It is important to discuss any side effects with your healthcare provider, as they may be able to provide recommendations to help manage them.

It is also important to inform your healthcare provider of any other medications or supplements you are taking, as they may interact with didanosine and affect its effectiveness or increase the risk of side effects.

Overall, didanosine is an important medication in the treatment of HIV infection and can help individuals living with the virus to manage their condition and improve their quality of life. If you have any questions or concerns about didanosine or its use, do not hesitate to speak with your healthcare provider.
