What is Cabenuva?

Cabenuva is a revolutionary long-acting injectable medication designed specifically for the treatment of HIV-1 infection.1Overview| Researched based study from This medication is used to prevent HIV infection in adults and children under the age of 12. Unlike traditional medications that require patients to adhere to a daily dosage schedule, Cabenuva offers a remarkable alternative.

It is a two-drug combination therapy comprising two intramuscular injections, cabotegravir and rilpivirine, which have been proven to provide sustained effectiveness over an extended period. Remarkably, Cabenuva only needs to be administered once a month, significantly reducing the treatment burden for patients.1Overview| Researched based study from

It functions by preventing the HIV from replicating, lowering the viral load, and assisting in the long-term maintenance of viral suppression

Cabenuva is a revolutionary long-acting injectable medication designed specifically for the treatment of HIV-1 infection. This medication is used to prevent HIV infection in adults and children under the age of 12.


What is the primary use of Cabenuva?

The most common uses of Cabenuva are explained below:

  • Cabenuva is prescribed to patients who have already experienced viral suppression, it helps by keeping the viral load low and stopping the spread of the infection.1Uses| Researched based study from
  • Cabenuva is given by a medical professional once a month as it provides a convenient treatment option. For people with HIV, this long-acting injectable formulation eliminates the need for daily oral medications.
  • Cabenuva may aid in raising treatment compliance. It guarantees steady drug levels in the body and lowers the chance of missed doses, improving medication compliance overall.


What is the typical dosage of Cabenuva?

Cabotegravir and rilpivirine, two different injectable medications, make up the dosing regimen for Cabenuva. Cabenuva dosage recommendations are as follows:

Phase I

  • It’s crucial to achieve viral suppression with an oral antiretroviral therapy (ART) regimen before taking Cabenuva.
  • For approximately one-month (typically 28 days), oral cabotegravir (30 mg) and oral rilpivirine (25 mg) tablets must be taken once daily. This stage assists in determining whether the drugs are well-tolerated and successful in sustaining viral suppression.

Phase II

  • Following the conclusion of the initiation phase, the maintenance phase starts. Cabenuva is given as a long-acting injectable therapy during this stage. Every four weeks (once per month), cabotegravir and rilpivirine are administered intramuscularly. A medical professional typically administers the injections in the buttocks. To keep the desired therapeutic levels of the medications in the body during the maintenance phase, it’s crucial to administer the injections consistently and on time.

Which medications and drug combinations can interact with Cabenuva?

It is advised to disclose any ongoing medication to your healthcare provider before proceeding with Cabenuva treatment.

The following are some examples of drugs and medical procedures that could interact with Cabenuva:

Drugs that stimulate or suppress liver enzymes

  • Rilpivirine, a substance in Cabenuva, is metabolized by liver enzymes. The levels of rilpivirine in the body can be impacted by medications that either stimulate or inhibit these enzymes.
  • Examples include the antifungal drugs rifampin, rifabutin, carbamazepine, phenytoin, and St. John’s wort. To prevent interactions, your doctor may need to change the dosage or think about using different medicines.

Drugs that lower stomach acid

  • Drugs that lower stomach acid, like proton pump inhibitors (PPIs) or H2 blockers, can interfere with the absorption of rilpivirine.
  • To maximize absorption, taking Cabenuva with food is generally advised. For detailed instructions on taking medications that reduce acid, speak with your doctor.

Drugs that alter heart rhythm

  • Cabenuva contains rilpivirine, which can lengthen the QT interval, an indicator of the electrical activity of the heart.
  • Certain antibiotics, antifungals, and some psychiatric drugs may raise the risk of abnormal heart rhythms because they also affect the QT interval. This interaction will be taken into account by your healthcare provider as they keep an eye on your cardiac health.

Other antiretroviral drugs

  • There may be concerns about possible drug interactions or overlapping drug effects when switching from other antiretroviral therapies to Cabenuva. To keep track of the effect of Cabenuva on your overall body, the healthcare professional will look for daily changes, and keep a track of it for understanding your case.
