What Is This Medicine Exactly?
Simply put, this treatment is an antiviral medicine that fights the human immunodeficiency virus (HIV). It is widely known under the brand name Cabenuva. The biggest benefit of this treatment is that instead of swallowing pills every day, a doctor injects the medicine directly into your muscle.
You can receive this injection either once a month or once every two months, depending on what your doctor prescribes. This flexibility offers a wonderful relief for many people who struggle with daily pill routines.
Important to remember: This medicine does not cure HIV. Instead, its main job is to keep the virus under control in your body. Also, even though this injection lowers the risk of passing HIV to someone else, it does not stop transmission completely. You still need to practice safe sex and use protection.
Things to Tell Your Doctor Before Starting Treatment
Before you start receiving this injection, sharing a complete medical history with your doctor is vital. Tell your doctor right away if you have any of the following health conditions:
- Heart problems: If you have any current or past history of heart conditions or rhythm issues.
- Liver problems: If your liver does not function properly or if you have a history of hepatitis.
- Mental health concerns: If you have experienced depression, severe anxiety, or other mental health challenges.
- Allergies: If you have known allergies to Cabotegravir, Rilpivirine, or any other medicines, foods, or dyes.
- Pregnancy and breastfeeding: If you are pregnant, planning to become pregnant, or currently nursing a baby.
Your doctor uses this health information to decide safely if this injectable treatment is the right choice for you.

You cannot take this medicine at home by yourself. A trained doctor must give the injection into your muscle at a clinic or hospital.
The most crucial rule is to never miss your scheduled injection appointment. If you miss or delay your doses, the HIV in your body can adapt and build resistance to the medicine. When drug resistance happens, treating the virus becomes much harder. Keep taking your injections on time until your doctor tells you otherwise.

In certain special situations and under strict medical supervision, doctors may prescribe this treatment to young people and teenagers aged 12 and older. Close monitoring ensures it remains safe and effective for growing bodies.

Because doctors give this in a clinic, receiving an overdose is very rare. However, if you ever suspect you received too much, call your local poison control center right away or go to the nearest hospital emergency department (ER / A&E) right away.
This medicine is prescribed only for you. Never share your medicine or your clinic schedule with anyone else.
