If you are living with HIV and managing your condition with daily medication, you understand the commitment and occasional challenges involved. But advancements in medicine mean new treatment options are emerging. Today, we'll discuss a groundbreaking alternative to daily pills: a long-acting injectable therapy administered monthly or every two months. This is the combination of Cabotegravir and Rilpivirine.
What Exactly Is This Treatment?
This treatment combines two powerful antiretroviral medications, Cabotegravir and Rilpivirine. Both belong to a class of drugs that fight the Human Immunodeficiency Virus (HIV). The primary function of this injectable therapy is to control the replication of HIV within your body. Essentially, it works by limiting viral growth, providing relief to your immune system.
Important Note: This injectable therapy is not a cure for HIV or AIDS. Furthermore, even while on treatment, there remains a risk of transmitting the virus to others. Therefore, practicing safe sex is crucial. This treatment also does not protect against other sexually transmitted infections (STIs).
This medication is commercially available under the brand name CABENUVA.
Essential Information for Your Doctor Before Starting
Before determining if this treatment is right for you, your healthcare provider needs a complete understanding of your medical history. It's crucial to openly and honestly discuss any of the following conditions with your doctor:
Heart Conditions
Inform your doctor if you have any existing or past heart problems.
Liver Disease
Disclose any history of liver conditions, such as hepatitis.
Mental Health Issues
Share any past or current mental health conditions like depression, especially if you are currently receiving treatment for them.
Allergies
Mention any known allergies to Cabotegravir, Rilpivirine, other medications, foods, or substances.
Pregnancy Plans
Inform your doctor if you are currently pregnant or planning to become pregnant in the near future.
Breastfeeding
Let your doctor know if you are breastfeeding.
This information is vital for ensuring the treatment's effectiveness and your safety.
How Is the Injection Administered?
This is not a self-administered injection. It must be given by a trained healthcare professional in a clinical setting, typically injected into a muscle.
Adherence is Key
Missing doses can allow the HIV virus to develop resistance to the medication and other HIV treatments. This means the drugs may become less effective. Therefore, it's essential to receive your injections on schedule as prescribed by your doctor until they advise you to stop.
Use in Adolescents
In selected cases, this injectable therapy might be recommended for adolescents aged 12 and older, but requires careful medical supervision.
What If I Miss a Dose or Have an Emergency?
Overdose
If you suspect an overdose, immediately contact the National Poisons Information Centre or go to the nearest hospital's Emergency Treatment Unit (ETU).
Missed Dose
If you miss your scheduled injection, contact your doctor or clinic immediately for guidance on rescheduling.
This medication is prescribed specifically for you. Never share it with anyone else.
Potential Drug Interactions
Certain other medications can interfere with the effectiveness of this injectable therapy. It's crucial to inform your doctor about all medications you are taking, including prescription drugs, over-the-counter medicines, herbal remedies, and dietary supplements.
| Drug Class | Examples and Details |
|---|---|
| Certain Anti-Seizure Medications | Carbamazepine, oxcarbazepine, phenobarbital, phenytoin. |
| High-Dose Dexamethasone | A corticosteroid. |
| Certain Tuberculosis Medications | Rifabutin, Rifampin, Rifapentine. |
| St. John's Wort | An herbal supplement. |
| Some Antibiotics | Azithromycin, clarithromycin, erythromycin (use with caution under medical guidance). |

What Should I Monitor While on This Treatment?
Regular Medical Check-ups
Your doctor will monitor your progress with regular appointments and blood tests to assess the treatment's effectiveness, how it affects your body, and viral load levels.
Preventing HIV Transmission
As mentioned earlier, this treatment does not cure HIV. The virus can still be transmitted through blood or sexual contact. Discuss effective prevention strategies with your doctor.
Serious Skin Reactions
A serious skin reaction can occur within weeks or months of starting treatment. Contact your doctor immediately if you develop a rash, especially if accompanied by fever or flu-like symptoms. The rash might be red or purplish, potentially blistering and peeling. A red rash with fever and swollen lymph nodes is also a sign to seek immediate medical attention.
