What is Viread?

Viread is an antiviral medicine that prevents human immunodeficiency virus (HIV) or hepatitis B from multiplying in your body.

Viread is used to treat HIV, the virus that can cause acquired immunodeficiency syndrome (AIDS). This medicine is not a cure for HIV or AIDS.

Viread is also used to treat chronic hepatitis B infection.

Viread is for use in adults and children at least 2 years old and weighing at least 22 pounds (10 kilograms).

Warnings

If you have hepatitis B, it may become active or get worse after you stop using Viread. You may need frequent liver function tests for several months.

Do not change your dose or stop using Viread without your doctor's advice. If you have ever had hepatitis B, stopping treatment with tenofovir can cause acute exacerbations of hepatitis B. You will need frequent blood tests to check your liver function.

Do not take Viread together with adefovir (Hepsera), or with combination medicines that contain tenofovir (Atripla, Biktarvy, Cimduo, Complera, Descovy, Genvoya, Odefsey, Stribild, Symfi, or Truvada).

Viread is not recommended in patients with end stage renal disease.
