Lenacapavir - injection
Lenacapavir - injection
Lenacapavir is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. Lenacapavir belongs to a class of drugs known as capsid inhibitors. It blocks the virus from growing and infecting more cells.
Lenacapavir is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, continue to take all HIV medications exactly as prescribed by your doctor. Use an effective barrier method (latex or polyurethane condoms/dental dams) during sexual activity as directed by your doctor. Do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.
Read the Patient Information Leaflet if available from your pharmacist before you start using lenacapavir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
This medication is given by injection under the skin as directed by your doctor, usually once every 6 months. It is given by injection into the stomach/abdomen area by a health care professional. At the beginning of treatment, you will also be using the tablet form of the medication for 2 or 3 doses. Follow your doctor's instructions carefully on when to take the tablet form of lenacapavir and when to get your injection of lenacapavir.
It is very important to keep using this medication (and other HIV medications) exactly as prescribed by your doctor. Do not skip any doses.
For the best effect, use this medication at evenly spaced times. To help you remember, mark your calendar to keep track of when to get the next dose.
Do not stop using this drug (or other HIV medicines) even for a short time unless directed to do so by your doctor. Doing so may cause the amount of virus to increase, make the infection more difficult to treat (resistant).
Injection site pain, swelling, redness, itching, bruising, or a hardened mass or lump may occur. Nausea may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including:
