Uses For Kaletra
Lopinavir and ritonavir combination is used with other medicines in the treatment of the infection caused by the human immunodeficiency virus (HIV). HIV is the virus responsible for acquired immune deficiency syndrome (AIDS). It is used to slow the progression of disease in patients infected with HIV who have advanced symptoms, early symptoms, or no symptoms at all.
Lopinavir and ritonavir combination will not cure or prevent HIV infection or AIDS. It helps keep HIV from reproducing and appears to slow down the destruction of the immune system. This may help delay the development of problems usually related to AIDS or HIV disease. Lopinavir and ritonavir combination will not keep you from spreading HIV to other people. People who receive this medicine may continue to have other problems usually related to AIDS or HIV disease.
This medicine is available only with your doctor's prescription.
Before Using Kaletra

Safety and efficacy have not been established. Kaletra® should not be used once a day in children. Kaletra® oral liquid should not be given to premature infants.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of lopinavir and ritonavir combination in the elderly.
