Raltegravir

This form:

Pronounced

"RAL-te-GRA-vir"

Common brand names:

Isentress

Uses

Raltegravir 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. Raltegravir is known as an integrase inhibitor. It blocks the virus from growing and infecting more cells.

Raltegravir 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.

Other Uses

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This product may also be used to lessen the risk of HIV infection after contact with the virus (for example, due to a needle stick). Ask your doctor for more details.

How to Use This Medication

Read the Patient Information Leaflet if available from your pharmacist before you start taking raltegravir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once or twice daily.

The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

The manufacturer directs to swallow this medication whole. However, many similar drugs (immediate-release tablets) can be split/crushed. Follow your doctor's directions on how to take this medication.

Avoid using antacids that contain aluminum or magnesium while taking this medication. These antacids can make raltegravir work less well.

It is very important to keep taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not skip any doses.

Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.

Do not take less of this drug than prescribed or stop taking it (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 and/or make the infection more difficult to treat (resistant).

For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time(s) every day.

Do not switch between the film-coated tablet, the chewable tablet, or the powder packet for oral suspension forms of raltegravir without asking your doctor or pharmacist first.
