Viread (tenofovir disoproxil fumarate) is a prescription antiviral medication used to treat human immunodeficiency virus type 1 (HIV-1) and chronic hepatitis B virus (HBV) infection. It helps reduce the amount of virus in the body, allowing the immune system and liver to function more effectively and lowering the risk of complications associated with these infections.
Viread is used as part of a combination treatment regimen for HIV-1 infection in adults and children 2 years of age and older. HIV attacks the immune system, making it more difficult for the body to fight infections and certain illnesses.
When used together with other antiretroviral medications, Viread can help:
Although Viread can effectively control HIV, it is not a cure for HIV infection. Continued treatment is necessary to keep the virus under control.
Viread is also approved for the treatment of chronic hepatitis B virus (HBV) infection in adults and adolescents 12 years of age and older.
Hepatitis B is a viral infection that affects the liver and can lead to long-term complications if left untreated, including:
By lowering the amount of hepatitis B virus in the body, Viread can help reduce liver damage and support long-term liver health.
Viread belongs to a group of medications called nucleotide reverse transcriptase inhibitors (NRTIs). These medications work by interfering with the ability of viruses to make copies of themselves.
For both HIV and hepatitis B, Viread blocks an important viral enzyme that is required for viral replication. By preventing the virus from reproducing, the medication helps reduce the amount of virus circulating in the body.
As viral levels decrease, Viread can help:
While Viread does not cure HIV or hepatitis B, it can be an important part of a long-term treatment plan. Taking Viread exactly as prescribed and attending regular follow-up appointments can help ensure the medication remains effective and supports your overall health.
Viread should be taken exactly as prescribed by your healthcare provider. It is available as an oral tablet and is typically taken once daily, with or without food. Swallow the tablet whole with a glass of water.
To achieve the best results, take Viread at approximately the same time each day. Maintaining a consistent dosing schedule helps keep a steady level of medication in your body, which is important for controlling HIV or hepatitis B infection. Setting a daily reminder or using a pill organizer may help you remember your doses.
The appropriate dose of Viread depends on several factors, including your medical condition, kidney function, response to treatment, and, for children, body weight. Your healthcare provider will determine the dose that is most appropriate for your individual needs.
For adults and pediatric patients weighing at least 35 kg (77 pounds), the usual dose is:
Viread may be taken with or without food unless your healthcare provider instructs otherwise.
Taking Viread consistently is extremely important. Missing doses, stopping treatment, or changing your dose without medical advice can allow the virus to multiply and may make treatment less effective.
For people living with HIV, skipping doses can increase the risk of developing drug-resistant virus strains, which can make future treatment more difficult. For people with chronic hepatitis B, stopping Viread suddenly may cause the infection to worsen and could lead to serious liver complications.
For these reasons:
If you miss a dose of Viread, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule.
Do not take two doses at the same time to make up for a missed dose.
While taking Viread, your healthcare provider may regularly monitor your:
These tests help ensure that the medication is working effectively and allow your healthcare provider to identify any potential side effects early.
When taken consistently and as directed, Viread can help control HIV or chronic hepatitis B infection, reduce viral levels in the body, and support long-term health outcomes.
Viread (Tenofovir Disoproxil Fumarate) is available in the following forms and strength:
Before taking Viread, tell your healthcare provider about all of your medical conditions, especially if you have kidney disease, liver disease, hepatitis B, bone problems, or are taking other medications. Regular monitoring may be required during treatment to help ensure the medication remains safe and effective.
Although rare, Viread and other medications in the same drug class have been associated with lactic acidosis, a serious condition caused by a buildup of lactic acid in the blood. In rare cases, this condition can be life-threatening.
Viread has also been associated with severe liver problems, including enlarged fatty liver (hepatomegaly with steatosis).
Seek immediate medical attention if you experience symptoms such as:
If you have chronic hepatitis B, stopping Viread suddenly may cause the infection to worsen significantly. This can lead to serious liver complications and, in some cases, liver failure.
Do not stop taking Viread without first consulting your healthcare provider. If treatment is discontinued, your healthcare provider may monitor your liver function closely for several months.
For people with HIV, Viread should be used as part of a complete antiretroviral treatment regimen. Using Viread alone in someone with undiagnosed or untreated HIV infection may increase the risk of the virus becoming resistant to treatment.
Your healthcare provider may perform HIV testing before starting Viread, particularly if it is being prescribed for hepatitis B treatment.
Viread can affect kidney function and has been associated with serious kidney-related side effects, including:
Your healthcare provider may perform blood and urine tests before and during treatment to monitor kidney health.
Tell your healthcare provider if you experience symptoms such as:
The risk of kidney problems may be higher if Viread is taken with other medications that can affect the kidneys.
Tell your healthcare provider about all medications you take, especially:
Viread has been associated with decreased bone mineral density, which may weaken bones over time and increase the risk of fractures.
People who may require closer monitoring include those with:
Your healthcare provider may recommend bone density testing if you are at increased risk.
As HIV treatment begins to improve immune system function, some people may develop immune reconstitution syndrome. This occurs when the recovering immune system begins responding to previously hidden infections, causing inflammation and new symptoms.
Contact your healthcare provider if you develop new symptoms after starting treatment.
People with existing liver disease or a history of hepatitis B should use Viread with caution. Additional monitoring may be needed to assess liver function throughout treatment.
Viread is generally not recommended for individuals with severe liver impairment unless specifically advised by a healthcare provider.
Viread may cause:
Regular laboratory monitoring can help identify these changes early and allow treatment adjustments if necessary.
Taking Viread exactly as prescribed and maintaining regular medical monitoring can help maximize the benefits of treatment while reducing the risk of serious complications.
The length of treatment with Viread depends on the condition being treated and your individual response to therapy. For people with chronic hepatitis B, treatment is often long term and may continue for several years. Studies have shown that long-term treatment can provide sustained suppression of the hepatitis B virus and may help improve liver health by reducing liver inflammation and slowing or reversing liver damage in some patients. For people living with HIV, Viread is typically used as part of an ongoing antiretroviral treatment regimen. Because HIV is a lifelong condition, treatment is generally continued indefinitely unless your healthcare provider recommends a change in therapy. Your healthcare provider will determine the most appropriate treatment duration based on your medical condition, laboratory results, and response to treatment.
Viread begins working soon after treatment starts by preventing the virus from making copies of itself. For people with HIV, a reduction in viral load may often be seen within the first four weeks of treatment. With continued use, many people experience a significant decline in viral load over the following months. In many cases, HIV viral levels may become undetectable within three to six months, depending on factors such as treatment adherence and individual response. For people with chronic hepatitis B, improvements in viral levels and liver function may also occur gradually over time. Regular blood tests help your healthcare provider monitor your progress and evaluate how well the medication is working.
Do not stop taking Viread without consulting your healthcare provider. For people with HIV, stopping Viread while continuing other HIV medications or interrupting treatment can allow the virus to multiply again. This may increase the risk of developing drug resistance, which can make HIV more difficult to treat in the future. For people with chronic hepatitis B, stopping Viread can cause the hepatitis B virus to become active again, potentially leading to severe liver inflammation, worsening liver disease, or permanent liver damage. If your healthcare provider decides that treatment should be stopped, they may closely monitor your liver function and viral levels for several months afterward.
Hair loss is not considered a common side effect of Viread. Most people taking the medication do not experience significant changes in hair growth. Although there have been occasional reports of hair loss with medications containing tenofovir, including some newer formulations, a direct relationship has not been clearly established. Hair loss can occur for many reasons, including medical conditions, nutritional deficiencies, stress, hormonal changes, and other medications. If you notice unusual hair thinning or hair loss while taking Viread, speak with your healthcare provider. They can help determine the possible cause and recommend appropriate evaluation or treatment if needed.
