(Generic available)

Tablets: lopinavir 100 mg/ritonavir 25 mg; lopinavir 200 mg/ritonavir 50 mg
Oral solution: lopinavir 80 mg/ritonavir 20 mg per mL (contains 42.4% alcohol)

Assessment ⬆ ⬇

Assess for change in severity of HIV symptoms and for symptoms of opportunistic infections during therapy.
Assess patient for signs of pancreatitis (nausea, vomiting, abdominal pain, increased serum lipase or amylase) periodically during therapy. May require discontinuation of therapy.
Assess patient for rash (mild to moderate rash usually occurs in the 2nd wk of therapy and resolves within 1–2 wk of continued therapy). If rash is severe (extensive erythematous or maculopapular rash with moist desquamation or angioedema) or accompanied by systemic symptoms (serum sickness-like reaction, Stevens-Johnson syndrome, toxic epidermal necrolysis), therapy must be discontinued immediately.

Lab Test Considerations:

Monitor viral load and CD4 counts regularly during therapy.
- Monitor triglyceride and cholesterol levels prior to initiating therapy and periodically during therapy.
- May cause hyperglycemia.
- Monitor liver function before and during therapy, especially in patients with underlying hepatic disease, including hepatitis B and hepatitis C, or marked transaminase elevations. May cause ↑ serum AST, ALT, GGT, and total bilirubin concentrations.
- Monitor serum lipase and amylase levels during therapy.
- Monitor blood glucose during therapy. May cause hyperglycemia.

Implementation ⬆ ⬇

Do not confuse Kaletra with Keppra.
PO: Tablets may be administered with or without food. DNC: Swallow whole, do not break, crush, or chew.
- Oral solution must be taken with food. Oral solution is light yellow to orange. Solution is stable if refrigerated until expiration date on label or 2 mo at room temperature. Oral solution should be avoided in premature babies until 14 days after their due date, or in full-term babies younger than 14 days of age unless a health care professional believes that the benefit of using Kaletra oral solution to treat HIV infection immediately after birth outweighs the potential risks. If oral solution is used in babies younger than 14 days, monitor for increases in serum osmolality, serum creatinine, and other signs of toxicity.
- Feeding Tube: Oral solution contains ethanol and propylene glycol. Use only compatible feeding tubes (silicone and polyvinyl chloride); avoid use with polyurethane feeding tubes due to potential incompatibility. Follow instructions for use of the feeding tube to administer the medicine.

Patient/Family Teaching ⬆ ⬇

Emphasize the importance of taking lopinavir/ritonavir as directed, at evenly spaced times throughout day. Do not take more than prescribed amount, and do not stop taking this or other antiretrovirals without consulting health care professional. Take missed doses as soon as remembered; do not double doses. Advise patient to read the Patient Information prior to taking this medication and with each Rx refill in case of changes.
Instruct parent/patient to measure oral solution carefully.
Instruct patient that lopinavir/ritonavir should not be shared with others.
Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications, especially St. John’s wort.
Inform patient that lopinavir/ritonavir does not cure HIV or prevent associated or opportunistic infections. Lopinavir/ritonavir may reduce the risk of transmission of HIV to others through sexual contact or blood contamination. Caution patient to use a condom during sexual contact and to avoid sharing needles or donating blood to prevent spreading HIV to others. Advise patient that the long-term effects of lopinavir/ritonavir are unknown at this time.
Instruct patient to notify health care professional immediately if rash, symptoms of lactic acidosis (tiredness or weakness, unusual muscle pain, trouble breathing, stomach pain with nausea and vomiting, cold especially in arms or legs, dizziness, fast or irregular heartbeat) or if signs of hepatotoxicity (yellow skin or whites of eyes, dark urine, light-colored stools, lack of appetite for several days or longer, nausea, abdominal pain) occur.
Inform patient that lopinavir/ritonavir may cause hyperglycemia. Advise patient to notify health care professional if increased thirst or hunger; unexplained weight loss; or increased urination occurs.
Caution patients taking sildenafil, vardenafil, or tadalafil of increased risk of associated side effects (hypotension, visual changes, sustained erection). Notify health care professional promptly if these occur.
Inform patient that redistribution and accumulation of body fat may occur, causing central obesity, dorsocervical fat enlargement (buffalo hump), peripheral wasting, breast enlargement, and cushingoid appearance. The cause and long-term effects are not known.
Rep: May cause fetal harm. Advise patients taking oral contraceptives to use a nonhormonal method of birth control during lopinavir/ritonavir therapy. Instruct patient to notify health care professional if pregnancy is planned or suspected and to avoid breastfeeding. Inform pregnant women exposed to lopinavir/ritonavir of pregnancy exposure registry that monitors pregnancy outcomes in women exposed to Kaletra during pregnancy. Enroll patient in the Antiviral Pregnancy Registry by calling 1-800-258-4263 to monitor maternal/fetal outcomes.
Emphasize the importance of regular follow-up exams and blood counts to determine progress and monitor for side effects.

Evaluation/Desired Outcomes ⬆ ⬇

Delayed progression of AIDS and decreased opportunistic infections in patients with HIV.
Decrease in viral load and improvement in CD4 cell counts.
