What is Cabenuva?

The Cabenuva injection kit contains cabotegravir and rilpivirine is separate single-dose vials. Cabotegravir and rilpivirine are antiviral medicines that prevent human immunodeficiency virus (HIV) from multiplying in your body. HIV is the virus that can cause acquired immunodeficiency syndrome (AIDS).

Cabenuva is a prescription medicine that is used without any other antiviral medicines to treat HIV. Cabenuva is not a cure for HIV or AIDS.

Cabenuva is for use in adults who have already used other antiviral HIV medications that have controlled their viral load.

Warnings

Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact, and some drugs should not be used together.

Before taking this medicine

You should not use the Cabenuva injection kit if you are allergic to cabotegravir or rilpivirine.

Many drugs can interact and cause dangerous effects. Some drugs should not be used together with Cabenuva. Your doctor may change your treatment plan if you also use:

Cabenuva can stay in your system for 12 months or longer. If you stop using Cabenuva, follow your doctor's instructions about using any other medicines during the first year afterward.

To make sure the Cabenuva injection kit is safe for you, tell your doctor if you have ever had:

  • a skin rash or an allergic reaction after taking medicine that contains cabotegravir or rilpivirine;

  • liver disease, including hepatitis B or C (cabotegravir and rilpivirine can affect the results of your liver function tests);

  • mental illness; or

  • long QT syndrome (in you or a family member).

Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether cabotegravir and rilpivirine will harm an unborn baby. However, HIV can be passed to your baby if the virus is not controlled during pregnancy. Your name may be listed on a registry to track any effects of cabotegravir and rilpivirine on the baby.

Women with HIV or AIDS should not breastfeed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.

How should I use the Cabenuva injection kit?

Use the Cabenuva injection kit exactly as prescribed by your doctor. Follow all directions on your prescription label. At least 28 days before your first injection, you will take cabotegravir and rilpivirine in tablet forms once per day with a meal. This "lead-in dose" will help determine that you can safely use these medicines together.

On the last day you take the tablets, you will receive your first injectable dose of this medicine. Cabenuva is injected into a muscle once per month. A healthcare provider will give you this medicine as 2 separate injections in opposite sides of your buttocks.

One month after your first injectable dose, you will begin regular monthly Cabenuva injections. You will be watched closely for about 10 minutes after each injection, to make sure you do not have a serious reaction.

The timing of your monthly injections is very important to the success of your HIV treatment. Your doctor may set a calendar day as your "target treatment date" to help keep you on schedule. If needed, you may receive an injection early or late, up to 7 days before or 7 days after your target date.

You must remain under the care of a doctor while receiving Cabenuva injections. Stay on schedule to get the most benefit. Missing doses can increase your risk of HIV that is resistant to medication.

If you stop using Cabenuva, you will need to start using other HIV medicines within 1 month to prevent your condition from becoming resistant.

You will need frequent medical tests. Cabenuva can have long lasting effects on your body (up to 12 months after your last dose). You may still need medical tests for a short time after you stop using this medicine.

What happens if I miss a dose?

Call your doctor for instructions if you miss an appointment for your Cabenuva injection.

If you plan to miss an injection by more than 7 days, you may need to take cabotegravir and rilpivirine tablets each day until your next monthly injection is due. You should start taking the tablets about 1 month after your last injection was given. If needed, daily tablets can replace Cabenuva injections for up to 2 months in a row.

If you miss an injection by more that 7 days and you have not started taking the medicine in tablet form, your doctor may need to decide whether or not Cabenuva is the best treatment for you.

What should I avoid while using Cabenuva?
