Important Safety Information¹

What is the most important information I should know about KALETRA?

KALETRA may cause serious side effects, including:

• Interactions with other medicines. It is important to know the medicines that should not be taken with KALETRA. For more information, see “Who should not take KALETRA?”
• Side effects in babies taking KALETRA oral solution. KALETRA oral solution contains alcohol (ethanol) and propylene glycol. Call your healthcare provider right away if your baby appears too sleepy or their breathing changes.
• Inflammation of your pancreas (pancreatitis). KALETRA can cause pancreatitis, which may be serious and may lead to death. People who have high levels of a certain fat (triglycerides) have a risk for developing pancreatitis. If you have advanced HIV-1 disease, you may have an increased risk of high triglyceride levels in your blood and pancreatitis. If you have a history of pancreatitis, you may have an increased risk of it recurring during treatment with KALETRA. Tell your healthcare provider if you have any signs or symptoms of pancreatitis including nausea, vomiting, and/or stomach area (abdominal) pain.
• Liver problems. Liver problems, including death, can happen in people who take KALETRA. Your healthcare provider should do blood tests before and during your treatment with KALETRA to check your liver function. If you have hepatitis B, hepatitis C, or other liver problems, you may have an increased risk for developing new or worsening liver problems during treatment with KALETRA. Tell your healthcare provider right away if you have any signs or symptoms of liver problems including loss of appetite, yellowing of skin or eyes (jaundice), dark-colored urine, pale-colored stools, itchy skin, and/or stomach area (abdominal) pain.
• Changes in your heart rhythm and the electrical activity of your heart can occur when taking KALETRA. These changes can lead to serious heart problems. Your risk for these problems may be higher if you already have a history of abnormal heart rhythm or other types of heart problems, or if you take other medicines that can affect your heart rhythm while you take KALETRA. Tell your healthcare provider right away if you experience dizziness, lightheadedness, fainting, and/or a sensation of abnormal heartbeats.

• If you take KALETRA during pregnancy, you should talk with your healthcare provider about how you can take part in an Antiretroviral Pregnancy Registry.
  • KALETRA oral solution contains alcohol (ethanol) and propylene glycol. You should not take KALETRA oral solution during pregnancy because there is no safe level of alcohol exposure during pregnancy. Tell your healthcare provider if you become pregnant during treatment with KALETRA.
  • KALETRA may reduce how well hormonal birth control works. Females who may become pregnant should use another effective form of birth control or an additional barrier method of birth control during treatment with KALETRA.

Do not breastfeed if you take KALETRA. You should not breastfeed if you have HIV-1 because of the risk of passing HIV-1 to your baby.

Tell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Many medicines interact with KALETRA. Keep a list of your medicines to show your healthcare provider and pharmacist. Do not start taking a new medicine without telling your healthcare provider. Your healthcare provider may need to change the dose of other medicines while you take KALETRA.

What are the possible side effects of KALETRA?

KALETRA can cause serious side effects including:
Diabetes and high blood sugar (hyperglycemia). You may develop new or worsening diabetes or high blood sugar during treatment with KALETRA. Tell your healthcare provider if you get any of the following signs or symptoms: urinate more often than usual, increased hunger or thirst, unusual weight loss, increase in your blood sugar levels. Your healthcare provider may need to start you on medicine to treat high blood sugar, or change your diabetes medicines.

Changes in your immune system (immune reconstitution syndrome) can happen when you start taking HIV-1 medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Call your healthcare provider right away if you start having new symptoms after starting your HIV-1 medicine.

Kidney stones have been reported in patients taking KALETRA.

Common side effects of KALETRA include diarrhea, nausea, vomiting, and increased fats in blood (triglycerides or cholesterol). These are not all of the possible side effects of KALETRA.
