Learn about the common and serious side effects of Cabenuva, an injectable HIV treatment, and how to manage them. Includes information on injection site reactions, allergic reactions, liver issues, and mental health effects.

Cabenuva, a groundbreaking medication for HIV treatment, offers a long-acting alternative to daily oral pills. It consists of two injectable medications, cabotegravir and rilpivirine, administered by a healthcare professional into the gluteal muscle. This treatment is typically given every one to two months, providing a convenient option for many individuals managing HIV. While Cabenuva offers significant advantages in terms of adherence and lifestyle flexibility, like all medications, it can have side effects. This article aims to provide a comprehensive overview of the potential side effects associated with Cabenuva, how to manage them, and when to seek medical attention.
The most frequently reported side effects of Cabenuva are related to the injection site. These reactions are generally mild and temporary, resolving within a few days. They can include:
To help manage injection site reactions, healthcare providers may recommend applying ice to the area before and after the injection. It's important to limit the ice application to no more than 15 minutes at a time. Patients are typically observed for about 10 minutes after receiving their injection to monitor for any immediate reactions.
Other common, though generally mild, side effects that some individuals may experience include:
If these mild side effects are persistent or bothersome, it is advisable to consult with your doctor or pharmacist. However, it is crucial not to stop Cabenuva treatment without consulting your doctor first, as this can impact the effectiveness of the medication.
While less common, Cabenuva can cause serious side effects that require immediate medical attention. It is vital to be aware of these potential risks and to contact your doctor right away if you experience any of the following:
In rare instances, a severe allergic reaction known as Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported after starting Cabenuva treatment. DRESS can occur between 2 to 8 weeks after the first injection. Symptoms to watch out for include:
If you experience symptoms of a severe allergic reaction, such as swelling, difficulty breathing, a serious skin rash, or fever, call 911 or your local emergency number immediately. These symptoms can be life-threatening and require urgent medical care.
Cabotegravir, one of the active ingredients in Cabenuva, can potentially cause liver problems. Signs of liver issues may include:
If you notice any of these symptoms, contact your doctor immediately. Your doctor may perform blood tests to check your liver function.
Although rare, some individuals may experience reactions shortly after the injection that could be serious. These might include difficulty breathing or dizziness. If you experience such symptoms, it's important to inform your healthcare provider immediately.
Some individuals taking Cabenuva have reported changes in mood, including depression or suicidal thoughts. It is crucial to discuss any new or worsening mental health symptoms with your doctor promptly. If you experience thoughts of harming yourself, please reach out for immediate help:

Cabenuva is an injectable treatment, while Biktarvy (bictegravir sodium/emtricitabine/tenofovir alafenamide) is an oral tablet taken daily. Both are used to treat HIV. The choice between these medications often depends on individual preferences, lifestyle, and medical history. Cabenuva offers the convenience of less frequent dosing, whereas Biktarvy requires daily adherence.
Most side effects associated with Cabenuva are mild and manageable. However, it is essential to stay vigilant and communicate openly with your healthcare provider about any changes you experience.
If you experience a side effect while taking Cabenuva and wish to report it to the U.S. Food and Drug Administration (FDA), you can visit MedWatch or call 800-FDA-1088. Reporting side effects helps the FDA monitor the safety of medications after they are approved.
Cabenuva represents a significant advancement in HIV treatment, offering a long-acting injectable option. While common side effects like injection site reactions are usually mild and manageable, it's crucial to be aware of the potential for serious side effects, including severe allergic reactions, liver problems, and mental health changes. Open communication with your healthcare provider is key to managing these side effects effectively and ensuring the best possible outcome for your treatment. Always seek medical advice if you have concerns or experience any unusual symptoms.
