Videx Dosage

Your Videx dosage will depend on several factors, such as age, weight, other medical conditions you have, and other medications you are taking. For treating adults (18 years old and older), the recommended starting Videx dose is 400 mg once daily (for those weighing at least 132 pounds). It is important to take your Videx dose as prescribed, as missing doses can cause the HIV virus to build up a resistance to the medication.

 

Videx Dosage: An Introduction

The dose of Videx® (didanosine) your healthcare provider recommends will vary depending on a number of factors, including:
 
  • Your weight
  • Your age
  • Other medical conditions you may have
  • Other medications you may currently be taking.
     
As always, do not adjust your Videx dose unless your healthcare provider specifically instructs you to do so.
 

Videx Dosing for Adults

The recommended Videx dose for treating adults (18 years old and older) with HIV or AIDS is based on weight. For people weighing 132 pounds or more, the recommended starting dose is Videx EC 400 mg once daily. For people who weigh less, the recommended dose is Videx EC 250 mg once daily. If you choose to take the liquid form of Videx (instead of the Videx EC capsules), the recommended starting dose is Videx 200 mg twice daily (for adults weighing 132 pounds or more) or Videx 125 mg twice daily (for adults weighing less).
 
Your healthcare provider may recommend a lower Videx dose if you have kidney disease, if you are taking certain other medications, or if you develop bothersome Videx side effects.
 

Videx Dosing for Adolescents and Children

Your child's healthcare provider will determine the Videx dose based on your child's age and body surface area (which is calculated using your child's height and weight). When treating children with Videx, healthcare providers typically recommend using Videx oral solution twice a day. The long-acting Videx EC capsules contain too much Videx for most children.
