Kaletra is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults and children 14 days of age and older. Kaletra is always used in combination with other HIV medicines.
Kaletra contains the following two different medicines combined in one pill:
PIs block an HIV enzyme called protease. (An enzyme is a protein that starts or increases the speed of a chemical reaction.) By blocking protease, the two drugs in combination prevent HIV from multiplying and can reduce the amount of HIV in the body.
HIV medicines can’t cure HIV/AIDS, but taking a combination of HIV medicines (called an HIV treatment regimen) every day helps people with HIV live longer, healthier lives. HIV medicines also reduce the risk of HIV transmission.
If you are taking HIV medicines, including Kaletra, don’t cut down on, skip, or stop taking them unless your health care provider tells you to.
