- If the patient is a child, tell the child's doctor if his or her weight changes. The dose of Lopinavir/Ritonavir may need to be changed.
- When your medicine supply is low, get more from your doctor or pharmacist as soon as you can. Do not stop taking Lopinavir/Ritonavir, even for a short period of time. If you do, the virus may grow resistant to the medicine and become harder to treat.
- Lopinavir/Ritonavir is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.
- Lopinavir/Ritonavir does not stop the spread of HIV to others through blood or sexual contact. Use barrier methods of birth control (eg, condoms) if you have HIV infection. Do not share needles, injection supplies, or items like toothbrushes or razors.

- Hemophilia patients - Report all bleeding episodes to your doctor.
- Lopinavir/Ritonavir may raise your blood sugar. High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, or have a fruit-like breath odor. If these symptoms occur, tell your doctor right away.
- Diabetes patients - Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Lab tests, including cholesterol and triglyceride levels, viral load, and liver function, may be performed while you use Lopinavir/Ritonavir. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Caution is advised when using Lopinavir/Ritonavir in CHILDREN; they may be more sensitive to its effects, especially skin rash.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of taking Lopinavir/Ritonavir while you are pregnant.
