Read the Medication Guide provided by your pharmacist before you start using didanosine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth usually once daily on an empty stomach, at least 1 and 1/2 hours before or 2 hours after a meal, or as directed by your doctor. Swallow the capsules whole. Do not crush, chew, or open the capsules. Doing so may decrease their effectiveness.
The dosage is based on your weight, medical condition, and response to treatment.
It is very important to continue taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not skip any doses. Do not increase your dose, take this drug more often than prescribed, or stop taking it (or other HIV medicines) even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.
This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same time(s) each day.
