PRECAUTIONS: Before taking this product, tell your doctor or pharmacist if you are allergic to either lopinavir or ritonavir; or to other HIV protease inhibitors such as amprenavir, indinavir or saquinavir; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver disease, diabetes, pancreatitis, high blood fat levels (cholesterol/triglycerides), heart problems (coronary artery disease, heart attack), bleeding problems (e.g., hemophilia), previous infection with certain diseases (e.g., hepatitis B infection, hepatitis C infection, tuberculosis).

Lopinavir/ritonavir may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that require immediate medical attention. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions section). Before using lopinavir/ritonavir, tell your doctor or pharmacist if you have any of the following conditions: certain other heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using lopinavir/ritonavir safely.

This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.

Because this product contains alcohol, severe nausea and vomiting may occur if you are also taking disulfiram or metronidazole with lopinavir/ritonavir solution. Consult your doctor or pharmacist before taking either of these medications.

Caution is advised when using this product in children. The alcohol in this product may cause an accidental overdose that could be serious. The propylene glycol in this product may also cause serious side effects in children (especially in newborns less than 14 days old).

This medication should be used only when clearly needed during pregnancy. Discuss the risks and benefits with your doctor.

It is not known if this medication passes into breast milk. Because breast milk can transmit HIV, do not breast-feed.
