Side Effects

Dizziness, diarrhea, or trouble sleeping may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: mental/mood changes (such as depression, anxiety, confusion), signs of kidney problems (such as a change in the amount of urine), unusual thirst, muscle cramps/weakness.

As your immune system gets stronger with HIV treatment, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including: unexplained weight loss, severe tiredness, muscle aches/weakness that doesn't go away, headaches that are severe or don't go away, joint pain, numbness/tingling of the hands/feet/arms/legs, vision changes, signs of infection (such as fever, chills, swollen lymph nodes, trouble breathing, cough, non-healing skin sores), signs of an overactive thyroid (such as irritability, nervousness, heat intolerance, fast/pounding/irregular heartbeat, bulging eyes, unusual growth in the neck/thyroid known as a goiter), signs of a certain nerve problem known as Guillain-Barre syndrome (such as unsteadiness, loss of coordination, trouble swallowing/speaking/chewing, trouble moving your eyes).

Rarely, this medication can cause severe (sometimes fatal) liver and blood problems (lactic acidosis). Tell your doctor right away if you develop symptoms of liver problems (such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine) or lactic acidosis (such as deep/rapid breathing, drowsiness, nausea/vomiting, unusual weakness).

Tenofovir may increase the risk of bone loss. Discuss the risks and benefits of treatment with your doctor, as well as the possible use of calcium and vitamin D to reduce this side effect. If you are at risk for bone loss, your doctor may monitor your bone mineral density. Tell your doctor right away if any of the following serious side effects occur: bone pain, easily broken bones.

Tenofovir can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Get medical help right away if you develop any rash.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

How long does it take for this medicine to take effect?

The onset of action for Viread, in terms of viral load reduction, can be observed within the first few weeks of treatment. However, it may take several weeks to months to see the maximal effect of the medication on viral load reduction and immune function improvement, as measured by CD4+ cell counts in HIV-1 infection or hepatitis B virus DNA levels in HBV infection.

How long do the effects of this medicine last?

Tenofovir disoproxil fumarate has a half-life of approximately 17 hours, but its antiviral effects last longer due to the sustained suppression of viral replication with continuous daily administration. The duration of the therapeutic effect is maintained with adherence to the prescribed daily dosing regimen.

Is it safe to consume alcohol while taking this medicine?

There are no direct interactions between alcohol and Viread reported. However, excessive alcohol consumption can exacerbate liver damage, particularly in individuals with hepatitis B or HIV/HBV coinfection. Patients are generally advised to limit alcohol intake to prevent additional liver stress.

Is this a habit forming medicine?

Viread is not habit-forming and does not have addictive properties. It is prescribed for its antiviral activity and does not produce euphoria or physical dependence.

Can this medicine be taken during pregnancy?

Viread is classified as FDA Pregnancy Category B, indicating that animal studies have not demonstrated a risk to the fetus but adequate and well-controlled studies in pregnant women are lacking. Tenofovir disoproxil fumarate is recommended for use during pregnancy only if clearly needed, and it has been used in pregnant women with HIV or HBV infection under medical supervision to prevent vertical transmission of the virus.

Can this medicine be taken while breast-feeding?

Tenofovir disoproxil fumarate is excreted into breast milk in small amounts. The World Health Organization (WHO) considers tenofovir to be compatible with breastfeeding in mothers with HIV infection when antiretroviral therapy is indicated for their own health. The decision to breastfeed while taking Viread should consider the potential benefits of breastfeeding, the mother's clinical need for the medication, and any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition.

Uses

This drug is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. Tenofovir belongs to a class of drugs known as nucleotide reverse transcriptase inhibitors (NRTIs).Tenofovir is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, continue to take all HIV medications exactly as prescribed by your doctor. Use an effective barrier method (latex or polyurethane condoms/dental dams) during sexual activity as directed by your doctor. Do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.Tenofovir is also used to treat a certain type of liver infection called chronic hepatitis B infection. It helps to decrease the amount of hepatitis B virus in your body by interfering with virus growth.

How to use Viread 40 Mg/Scoop (40 Mg/Gram) Oral Powder

Read the Patient Information Leaflet if available from your pharmacist before you start taking tenofovir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with food as directed by your doctor, usually once daily. The dosage is based on your medical condition and response to treatment. For children, the dosage is also based on weight.

Carefully measure the dose using the special measuring device/scoop provided. Do not use a household spoon because you may not get the correct dose. Mix tenofovir with 2 to 4 ounces (60 to 120 milliliters) of soft foods that can be swallowed without chewing (such as applesauce, baby food, yogurt). Do not mix tenofovir with liquid as this medication may float to the top of the liquid even after stirring. Take this medication right away after mixing to avoid bitter taste.

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 medications) 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.

For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time every day.

Warnings

If you have hepatitis B infection, your hepatitis symptoms may get worse or become very serious if you stop taking tenofovir. Talk with your doctor before stopping this medication. Your doctor will monitor liver tests for several months after you stop tenofovir. Tell your doctor right away if you develop symptoms of worsening liver problems.
