Patient Information

Important: Ask your healthcare provider or pharmacist about medicines that should not be taken with Odefsey. For more information, see the section Before taking Odefsey.

Read this Patient Information before you start treatment and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or treatment.

Important information

Odefsey can cause serious side effects, including:

  • Build-up of lactic acid in your blood (lactic acidosis). Lactic acidosis may happen in some people who take Odefsey or similar medicines (nucleoside analogs). Lactic acidosis is a serious medical emergency that can lead to death. Lactic acidosis can be hard to identify early, because the symptoms could seem like symptoms of other health problems. Call your healthcare provider right away if you get any of the following symptoms which could be signs of lactic acidosis:
    • feel very weak or tired
    • feel cold, especially in your arms and legs
    • have unusual (not normal) muscle pain
    • feel dizzy or lightheaded
    • have trouble breathing
    • have a fast or irregular heartbeat
    • have stomach pain with nausea or vomiting
  • Severe liver problems. Severe liver problems may happen in people who take Odefsey. In some cases, these liver problems can lead to death. Your liver may become large (hepatomegaly) and you may develop fat in your liver (steatosis). Call your healthcare provider right away if you get any of the following symptoms of liver problems:
    • your skin or the white part of your eyes turns yellow (jaundice)
    • light-colored bowel movements (stools)
    • nausea
    • dark “tea-colored” urine
    • loss of appetite
    • pain, aching, or tenderness on the right side of your stomach area
    You may be more likely to get lactic acidosis or severe liver problems if you are female, very overweight (obese), or have been taking Odefsey or a similar medicine containing nucleoside analog for a long time.
  • Worsening of Hepatitis B virus infection. Odefsey is not for use to treat chronic hepatitis B virus (HBV) infection. If you have hepatitis B virus (HBV) infection and take Odefsey, your HBV may get worse (flare-up) if you stop treatment. A “flare-up” is when your HBV infection suddenly returns in a worse way than before.
    • Do not run out of Odefsey. Refill your prescription or talk to your healthcare provider before your medicine is all gone.
    • Do not stop taking Odefsey without first talking to your healthcare provider.
    • If you stop taking Odefsey, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your HBV infection. Tell your healthcare provider about any new or unusual symptoms you may have after you stop treatment.

For more information about side effects, see the section Odefsey side effects.

What is Odefsey?

Odefsey is a prescription medicine that is used to treat Human Immunodeficiency Virus-1 (HIV-1) in people 12 years of age and older:

  • who have not received anti-HIV-1 medicines in the past and who have an amount of HIV-1 in their blood (this is called “viral load”) that is no more than 100,000 copies/mL, or
  • to replace their current anti-HIV-1 medicines:
    • in people who have been on the same anti-HIV-1 medicine regimen for at least 6 months, and
    • who have an amount of HIV-1 in their blood that is less than 50 copies/mL, and
    • have never failed past HIV-1 treatment.

HIV-1 is the virus that causes AIDS (Acquired Immune Deficiency Syndrome).

Odefsey contains the prescription medicines emtricitabine, rilpivirine and tenofovir alafenamide.

It is not known if this medicine is safe and effective in children under 12 years of age or who weigh less than 77 lb (35 kg).

Odefsey may help:

  • Reduce the amount of HIV-1 in your blood. This is called “viral load”.
  • Increase the number of CD4+ (T) cells in your blood that help fight off other infections.

Reducing the amount of HIV-1 and increasing the CD4+ (T) cells in your blood may help improve your immune system. This may reduce your risk of death or getting infections that can happen when your immune system is weak (opportunistic infections).

Odefsey does not cure HIV-1 infections or AIDS. You must keep taking HIV-1 medicines to control HIV-1 infection and decrease HIV-related illnesses.

Avoid doing things that can spread HIV-1 infection to others.

  • Do not share or re-use needles or other injection equipment.
  • Do not share personal items that can have blood or body fluids on them, like toothbrushes and razor blades.
  • Do not have any kind of sex without protection. Always practice safer sex by using a latex or polyurethane condom to lower the chance of sexual contact with semen, vaginal secretions, or blood.

Ask your healthcare provider if you have any questions about how to prevent passing HIV-1 to other people.

Who should not take Odefsey?

Do not take Odefsey if you also take a medicine that contains:

  • carbamazepine (Carbatrol, Epitol, Equetro, Tegretol, Tegretol-XR, Teril)
  • dexamethasone (Ozurdex, Maxidex, Decadron, Baycadron)
  • dexlansoprazole (Dexilant)
  • esomeprazole (Nexium, Vimovo)
  • lansoprazole (Prevacid)
  • omeprazole (Prilosec, Zegerid)
  • oxcarbazepine (Trileptal)
  • pantoprazole sodium (Protonix)
  • phenobarbital (Luminal)
  • phenytoin (Dilantin, Dilantin-125, Phenytek)
  • rabeprazole (Aciphex)
  • rifampin (Rifadin, Rifamate, Rifater, Rimactane)
  • rifapentine (Priftin)

  • have liver problems, including hepatitis B or C virus infection
  • have kidney problems
  • have a history of depression or suicidal thoughts
  • have bone problems
  • have any other medical conditions
  • are pregnant or plan to become pregnant. It is not known if Odefsey can harm your unborn baby. Tell your healthcare provider if you become pregnant during treatment.
    Pregnancy Registry: There is a pregnancy registry for women who take antiviral medicines during pregnancy. The purpose of this registry is to collect information about the health of you and your baby. Talk with your healthcare provider about how you can take part in this registry.
  • are breastfeeding or plan to breastfeed. Do not breastfeed if you take Odefsey.
    • You should not breastfeed if you have HIV-1 because of the risk of passing HIV-1 to your baby.
    • At least one of the medicines in Odefsey can pass to your baby in your breast milk. It is not known if the other medicines can pass into your breast milk.
    Talk with your healthcare provider about the best way to feed your baby.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Some medicines may interact with Odefsey. Keep a list of your medicines and show it to your healthcare provider and pharmacist when you get a new medicine.

  • You can ask your healthcare provider or pharmacist for a list of medicines that interact with Odefsey.
  • Do not start a new medicine without telling your healthcare provider. Your healthcare provider can tell you if it is safe to take Odefsey with other medicines.

How should I take Odefsey?

  • Take Odefsey exactly as your healthcare provider tells you to take it. Odefsey is taken by itself (not with other HIV-1 medicines) to treat HIV-1 infection.
  • Take Odefsey one time each day with a meal.
  • Do not change your dose or stop treatment without first talking with your healthcare provider. Stay under a healthcare provider’s care during treatment.
  • Do not miss a dose.
  • If you overdose, call your healthcare provider or go to the nearest hospital emergency room right away.
  • When your supply of medicine starts to run low, get more from your healthcare provider or pharmacy. This is very important because the amount of virus in your blood may increase if the medicine is stopped for even a short time. The virus may develop resistance to Odefsey and become harder to treat.

Odefsey side effects

Odefsey may cause serious side effects, including:

  • See Important information.
  • Severe skin rash and allergic reactions. Skin rash is a common side effect. Rash can be serious. Call your healthcare provider right away if you get a rash. In some cases, rash and allergic reaction may need to be treated in a hospital.

    • feel anxious or restless
    • have thoughts of hurting yourself (suicide) or have tried to hurt yourself
  • Change in liver enzymes. People with a history of hepatitis B or C virus infection or who have certain liver enzyme changes may have an increased risk of developing new or worsening liver problems during treatment. Liver problems can also happen during treatment in people without a history of liver disease. Your healthcare provider may need to do tests to check your liver enzymes before and during treatment.
  • Changes in body fat can happen in people who take HIV-1 medicine. These changes may include increased amount of fat in the upper back and neck (“buffalo hump”), breast, and around the middle of your body (trunk). Loss of fat from the legs, arms and face may also happen. The exact cause and long-term health effects of these conditions are not known.
  • Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV-1 medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider right away if you start having any new symptoms after starting your HIV-1 medicine.
  • New or worse kidney problems, including kidney failure. Your healthcare provider should do blood and urine tests to check your kidneys before you start and during treatment. Your healthcare provider may tell you to stop treatment if you develop new or worse kidney problems.
  • Bone problems can happen in some people who take Odefsey. Bone problems may include bone pain, softening or thinning (which may lead to fractures). Your healthcare provider may need to do tests to check your bones.

The most common side effects of rilpivirine, one of the medicines in Odefsey, include depression, trouble sleeping (insomnia), and headache.

The most common side effect of emtricitabine and tenofovir alafenamide, two of the medicines in Odefsey, is nausea.
