Cabenuva: A Comprehensive Guide to This Promising HIV Medication

Cabenuva is a medicine that combines two different drugs, cabotegravir and rilpivirine, which are antiviral medications that target a virus known as human immunodeficiency virus type 1 (HIV-1). People infected with this virus are at risk of developing acquired immune deficiency (AIDS), a condition in which a person is unable to fight back against infections. The two HIV medicines, cabotegravir and rilpivirine, are slowly released into your body and keep the HIV level low enough that it won’t be detected using normal screening methods. 

What Should I Know About Being Treated With Cabenuva?

Cabenuva can be given to people aged 12 years or older with a weight of at least 35 kg. It is an intramuscular injectable drug that can only be administered by a healthcare provider. This injection is usually given in the muscles of the buttocks (gluteal region). There are two options for beginning Cabenuva. Your healthcare provider may start you on oral tablets for one month before switching to Cabenuva, or they may begin Cabenuva right away. 

If started on the tablets, you will take two medications by mouth: Vocabria (cabotegravir) and Edurant (rilpivirine). These are the same two medications that make up Cabenuva. These two tablets will be swallowed daily, with a meal, for approximately 28 days. The last day of oral tablets will correspond with the first injection of Cabenuva.

If no oral tablets are used as a lead-in, Cabenuva will be given on the last day of your current antiviral therapy. 

Cabenuva is injected in two parts, with one part containing cabotegravir and the other part containing rilpivirine. They will be administered in separate gluteal sites, at least two centimeters apart. It is common for injections to be given in opposite gluteal muscles (left and right). Cabenuva can be given once a month or once every 2 months. Your healthcare provider will help determine the best treatment schedule for you.

Where To Begin

It is important that you always consult your physician at any time before starting Cabenuva and especially during the course of the treatment. If you have been using any previous medication,  have not taken the necessary tests first, or have any other active illness, then your physician will first determine if the treatment is suitable for you or not. Your physician will guide and instruct you on the precautions, expectations, and appointment schedule. 

It is also important that you show up for every appointment and do not miss any injections; otherwise, this may lead to treatment failure. Cabenuva is unique in that it has a flexible treatment window. Your injection can occur within 7 days before or 7 days after your designated appointment date. However, if you do miss out on a scheduled injection or intentionally want to discontinue treatment temporarily, you must contact your healthcare provider immediately to discuss further treatment options.

Who Should Not Use Cabenuva?

Not everybody will be able to tolerate this drug. A certain percentage of people develop an allergy to different substances or medicines. If you previously have used cabotegravir or rilpivirine and have experienced an allergic reaction to either medication, Cabenuva should not be used.

If you are currently taking any of the medicines listed below, you should not use Cabenuva as it may interact with the other medicines and potentially cause a reaction. These medicines include anticonvulsants, barbiturates, antituberculous antibiotics, and corticosteroids, among others. Some important ones to note are as follows:

• Carbamazepine
• Oxcarbazepine
• Phenobarbital 
• Rifabutin
• Rifampin
• Rifapentine
• Dexamethasone

Lactating mothers should also avoid breastfeeding their babies, as cabotegravir and rilpivirine can build up in the infant and may cause adverse effects. HIV-positive mothers are also advised not to breastfeed at all, even while not taking Cabenuva, as HIV-1-infected mothers can pass on the virus to their kids. 

It is currently unknown how this drug can affect fetuses within the mother’s womb. Pregnant women are advised not to take Cabenuva until it has been properly tested in clinical trials. 

Efectos secundarios

Typically, the most common side effects of Cabenuva are reactions at the injection site either due to improper administration or sensitivity to the drug.

Patients have reported the following on the injection site:

• Pain
• Tenderness
• Swelling
• Redness
• Itching

 

Aside from this, a patient may experience the following symptoms:

• Náuseas
• Fiebre
• Rash
• Dolor de cabeza

What To Do If You Experience Severe Side Effects

If you experience any form of a severe allergic reaction, contact your healthcare provider immediately. These symptoms include the following: 

• Dyspnea (difficulty breathing)
• Wheezing
• Blisters or sores on the body 
• Redness of the eyes 
• Swelling of any part of the face, lips, or tongue

Your liver might also be vulnerable to damage when on Cabenuva, especially if you have a history of liver disease such as hepatitis B or hepatitis C virus infection. This is why it is important to get your liver health checked before taking the drug. This can be done by giving a blood test known as a liver function test (LFT). This test should also be done regularly once on Cabenuva so that the health of your liver can be monitored. If there is any abnormality in your test before or during treatment, your healthcare provider will step in and may stop the usage of Cabenuva.

A few signs and symptoms of liver toxicity are as follows: 

• Jaundice (yellowing of the skin or eyes)
• Dark-colored urine
• Light-colored stool
• Loss of appetite
• Abdominal pain
• Generalized nausea

Your mood is also liable to change while on the drug. If you start feeling sad, anxious, restless, or have suicidal ideation, then you might have entered a state of depression. Do not hesitate to contact your healthcare providers and inform them of these changes.
