Generic Name: lopinavir and ritonavir (loe PIN a vir and ri TOE na veer)
Brand Names: Kaletra
What is Kaletra?
Kaletra contains a combination of lopinavir and ritonavir. Lopinavir and ritonavir are antiviral medications that prevent the human immunodeficiency virus (HIV) from multiplying in your body.
Kaletra is used to treat HIV, which causes the acquired immunodeficiency syndrome (AIDS).
Kaletra is not a cure for HIV or AIDS.
Kaletra can cause a serious heart problem, especially if you use certain other medicines at the same time. Tell your doctor about all your current medicines and any medicine you start or stop using.
Call your doctor at once if you have a headache with chest pain, fast or pounding heartbeats, and severe dizziness.
Before taking this medicine
You should not use Kaletra if you have ever had a severe allergic reaction to lopinavir or ritonavir.
Some medicines can cause unwanted or dangerous effects when used with Kaletra. Your doctor may need to change your treatment plan if you use any of the following drugs:
midazolam (oral syrup), triazolam;
sildenafil (Revatio for pulmonary arterial hypertension);
St. John's wort; or
an ergot medicine (ergotamine, dihydroergotamine, methylergonovine).
To make sure Kaletra is safe for you, tell your doctor if you have ever had:
liver disease (especially hepatitis B or C);
heart disease, heart rhythm disorder, or a family history of long QT syndrome;
low levels of potassium in your blood; or
a bleeding disorder such as hemophilia.
It is not known whether Kaletra will harm an unborn baby. But HIV can be passed to your baby if you are not properly treated during pregnancy. Take all of your HIV medicines as directed to control your infection.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of Kaletra on the baby.
Kaletra can make birth control pills or patches less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking this medicine.
Women with HIV or AIDS should not breast-feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
Kaletra is not approved for use by anyone younger than 14 days old. Premature infants should not receive the medication until it has been 14 days after their original due date.

HIV/AIDS is usually treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice. Every person with HIV or AIDS should remain under the care of a doctor.

Kaletra liquid contains alcohol. Avoid drinking alcohol while using this medicine.
Taking this medication will not prevent you from passing HIV to other people. Do not have unprotected sex or share razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person.
