What is Vocabria?

Vocabria is an antiviral medicine that prevents human immunodeficiency virus (HIV) from multiplying in your body. HIV is the virus that can cause acquired immunodeficiency syndrome (AIDS).

Vocabria is a prescription medicine used together with another antiviral called rilpivirine in adults with HIV. Cabotegravir and rilpivirine are to be used without any other antiviral medicines to treat HIV.

Vocabria and rilpivirine are given as a daily "lead-in dose" to help determine that you can safely use a combination form of these medicines given as a monthly injection.

Vocabria and rilpivirine may also be given short-term in place of the monthly injectable combination if you plan to miss an injection by more than 7 days.

Vocabria and rilpivirine is for use in adults who have already used other antiviral HIV medications that have controlled their viral load. These medicines are not a cure for HIV or AIDS.


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 Vocabria if you are allergic to cabotegravir.

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

To make sure Vocabria 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;

  • liver disease; or

  • mental illness.

Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether cabotegravir 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 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.

Vocabria is not approved for use by anyone younger than 18 years old.

How should I take Vocabria?

Take Vocabria exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Vocabria with rilpivirine is usually given once per day starting at least 28 days before you switch to the injectable combination.

Take Vocabria and rilpivirine with a meal. If you take the medicines at separate times, Vocabria may be taken with or without food.

On the last day you take Vocabria and rilpivirine tablets, you will receive your first injectable dose of these medicines.

If you take Vocabria with rilpivirine to replace a missed dose of the injectable combination, take Vocabria and rilpivirine tablets each day until your next monthly injection is due.

If you plan to miss a monthly injection by more than 7 days, start taking Vocabria and rilpivirine tablets about 1 month after your last injection was given. Keep taking the tablets each day until your next monthly injection is due.

If needed, daily Vocabria and rilpivirine tablets can replace the injectable combination for up to 2 months in a row.

You will need frequent medical tests.

You must remain under the care of a doctor while taking Vocabria and rilpivirine in tablet or injection form. 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 Vocabria and rilpivirine, you will need to start using other HIV medicines within 1 month to prevent your condition from becoming resistant.
