AIDS Home > Viread Dosage

The recommended Viread dosage for the treatment of hepatitis B or HIV/AIDS in adults is 300 mg once daily. If you have kidney disease, your healthcare provider may suggest taking the medication less frequently (such as once a week instead of once daily). It is important that you remember to take each dose; missing doses can increase the chance of HIV developing resistance to Viread.

Viread Dosage: An Introduction

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

Viread Dosage for HIV/AIDS in Adults

The recommended dose of Viread for treating adults with HIV or AIDS is 300 mg once daily. If you have kidney disease, your healthcare provider may recommend that you take the medication less frequently (such as every other day, twice a week, or even once weekly), depending on the severity of your kidney problems.

Viread Dosage for HIV/AIDS in Children

For treating HIV in adolescents and children (age 2 to 18 years), the recommended dosage is based on weight. The dosage is approximately 8 mg per kg (about 3.6 mg per pound) once daily. Children weighing less than 37.4 pounds should take the oral powder form, while heavier children can take the powder or the tablets (depending on swallowing preferences).
For the powder (which is measured in scoops, with 40 mg per scoop), the dose is rounded to the nearest full or half scoop (smaller amounts cannot be accurately measured).
