Cabotegravir - Intramuscular


Patient Medicine Information
Why do I need this medicine?
Cabotegravir is used together with other medicine to treat human immunodeficiency virus (HIV) infection which can lead to acquired immune deficiency syndrome (AIDS).

This medicine is not a cure for HIV infection. It only helps to keep the virus in check and can help improve the quality of life. This medicine does not prevent the spread of HIV to other people.
How do I use this medicine?
Cabotegravir injection is to be given intramuscularly (into the muscle), usually into the muscles of the buttocks).

Your doctor or nurse will administer the injection for you.

Use Cabotegravir at regular intervals. Do not skip any doses. You must complete the entire course of this medicine. If you don't, the infection will not be properly controlled.
What should I do if I have forgotten to use this medicine?
Ensure that you keep all appointments with your doctor so that you do not miss any doses. Your doctor also needs to regularly monitor your response to Cabotegravir.

If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.
When should I not use this medicine?
Do not use Cabotegravir if you ever had an allergic reaction (e.g. rashes, breathlessness, swollen eyes) to this medicine or any of its ingredients.

Do not take this medicine if you are breastfeeding.

Do not use Cabotegravir with medicines used to treat epilepsy (fits or seizures) or an infection known as tuberculosis. Please see the section "Can I take this with other medicines?" below for more information.
What should I take note of while using this medicine?
Inform your doctor if you have liver disease or hepatitis B infection (contagious liver infection caused by a virus that is spread through contact with infected blood or other body fluids).

Let your doctor know if you are pregnant.

Inform your doctor if you are breastfeeding. It is best that you do not breastfeed as HIV passes into the breast milk. Avoid breastfeeding in order to reduce the risk of passing HIV to your baby. It is recommended to give your baby commercial infant formula provided that you have access to clean water and facilities.

This medicine does not reduce your risk of passing HIV infection to others through sexual contact or contamination with infected blood. Ensure that you use proper precautions to avoid spreading HIV infection to others.

Both this medicine and HIV may weaken your immune system, leaving you more vulnerable to infections. Avoid crowded places or those who are sick to minimise the risk of catching an infection. While undergoing treatment, you may develop other infections or experience other health problems. Always keep your doctor updated on your condition and go for your appointed check-ups.

Why is it important to keep my appointments with the doctor?

Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medication regularly.
  • Routine tests (e.g. liver function) may be done while you are being treated with this medicine. Your doctor will advise you about how often you need to have these tests.
  • Regular monitoring signs of skin reactions, liver toxicity, or changes in mood may also be needed.
