This combination product contains two medications: lopinavir and ritonavir. This product is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. Both lopinavir and ritonavir belong to a class of drugs known as HIV protease inhibitors. Ritonavir increases ("boosts") the levels of lopinavir. This helps lopinavir work better.

Lopinavir/ritonavir is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, continue to take all HIV medications exactly as prescribed by your doctor. Use an effective barrier method (latex or polyurethane condoms/dental dams) during sexual activity as directed by your doctor. Do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This product may also be used to lessen the risk of HIV infection after contact with the virus (for example, due to a needle stick). Ask your doctor for more details.

Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking lopinavir/ritonavir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once or twice daily. Swallow the tablets whole. Do not crush, break or chew the tablets.

The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Children's dosage is also based on age and body size. Once-daily dosing of this medication is not recommended for children younger than 18 years of age.

If you are taking didanosine in addition to this product, you can take it at the same time as this product, but take them both without food.

It is very important to keep taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not skip any doses.

For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time(s) every day.

Do not take more or less of this drug than prescribed or stop taking it (or other HIV medicines) even for a short time unless directed to do so by your doctor. Doing so may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.

Diarrhea, nausea, vomiting, stomach upset, gas, headache, and trouble sleeping may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including:

• unexplained weight loss
• severe tiredness
• muscle aches/weakness that doesn't go away
• headaches that are severe or don't go away
• joint pain
• numbness/tingling of the hands/feet/arms/legs
• vision changes
• signs of infection (such as fever, chills, swollen lymph nodes, trouble breathing, cough, non-healing skin sores)
• signs of an overactive thyroid (such as irritability, nervousness, heat intolerance, fast/pounding/irregular heartbeat, bulging eyes, unusual growth in the neck/thyroid known as a goiter)
• signs of a certain nerve problem known as Guillain-Barre syndrome (such as unsteadiness, loss of coordination, trouble swallowing/speaking/chewing, trouble moving your eyes)

Tell your doctor right away if you have any serious side effects, including:

• nausea/vomiting that doesn't stop
• increased thirst
• increased urination
• confusion
• stomach/abdominal pain
• yellowing eyes/skin
• dark urine

Get medical help right away if you have any very serious side effects, including:

• symptoms of a heart attack (such as chest/jaw/left arm pain, shortness of breath, unusual sweating)
• severe dizziness
• fainting
• slow/fast/irregular heartbeat

Changes in body fat may occur while you are taking this medication (such as increased fat in the upper back and stomach areas, decreased fat in the arms and legs). The cause and long-term effects of these changes are unknown. Discuss the risks and benefits of treatment with your doctor, as well as the possible use of exercise to reduce this side effect.

This medication may cause an increase in blood fat levels (cholesterol and triglycerides). Cholesterol and triglyceride testing should be done before and occasionally during treatment with this medication. Consult your doctor or pharmacist for more information.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:

• rash
• itching/swelling (especially of the face/tongue/throat)
• severe dizziness
• trouble breathing

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Before taking this product, tell your doctor or pharmacist if you are allergic to either lopinavir or ritonavir; 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 (such as hemophilia)
• previous infection with certain diseases (such as hepatitis B infection, hepatitis C infection, tuberculosis)

Lopinavir/ritonavir may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using lopinavir/ritonavir, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions:

• certain 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.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).

Tell your doctor if you are pregnant before using this medication. Treatment can lower the risk of passing HIV infection to your baby. Discuss the risks and benefits with your doctor.

This medication passes into breast milk. Because breast milk may transmit HIV, consult your doctor before breastfeeding.
