Why is this medication prescribed?
The combination of lopinavir and ritonavir is used with other medications to treat human immunodeficiency virus (HIV) infection. Lopinavir and ritonavir are in a class of medications called protease inhibitors. They work by decreasing the amount of HIV in the blood. When lopinavir and ritonavir are taken together, ritonavir also helps to increase the amount of lopinavir in the body so that the medication will have a greater effect. Although lopinavir and ritonavir will not cure HIV, these medications may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other life-style changes may decrease the risk of transmitting the HIV virus to other people.
How should this medicine be used?
The combination of lopinavir and ritonavir comes as a tablet and a solution (liquid) to take by mouth. It is usually taken twice a day, but may be taken once a day by certain adults. The solution must be taken with food. The tablets may be taken with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lopinavir and ritonavir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole; do not split, chew, or crush them.
If you are using the solution, shake it well before each use to mix the medication evenly. Use a dose-measuring spoon or cup to measure the correct amount of liquid for each dose, not a regular household spoon.
Continue to take lopinavir and ritonavir even if you feel well. Do not stop taking lopinavir and ritonavir without talking to your doctor. If you miss doses, take less than the prescribed amount, or stop taking lopinavir and ritonavir, your condition may become more difficult to treat.
