 Precautions

Pregnancy: Category C. Lactation: HIV-infected mothers should not breastfeed their infants. Zidovudine: Excreted in breast milk. Abacavir and Lamivudine: Undetermined. Children: Safety and efficacy not established in children weighing less than 40 kg. Elderly: Select dose with caution, reflecting greater frequency of decreased hepatic, renal, or cardiac function and comorbidity. Bone marrow suppression: Use with caution in patients who have bone marrow compromise evidenced by granulocyte count less than 1000 cells/mm³ or hemoglobin less than 9.5 g/dL. Hypersensitivity: Fatal hypersensitivity reactions have been associated with abacavir use and have occurred within hours after reintroduction of abacavir in patients who have no identified history or unrecognized symptoms of hypersensitivity. If hypersensitivity cannot be ruled out, do not restart therapy. Renal function impairment Because this is a fixed-dose tablet, do not use for patients requiring dosage adjustments (eg, Ccr less than 50 mL/min or patients experiencing dose-limiting adverse effects). Lactic acidosis/Severe hepatomegaly: Steatosis have been reported.

Drug Interactions ::

 Interactions

Doxorubicin, ribavirin, stavudine: Antagonistic relationship has been demonstrated between these agents and zidovudine. Ganciclovir, interferon-alpha, other bone marrow suppressive or cytotoxic agents: May increase the hematologic toxicity of zidovudine. Trimethoprim/sulfamethoxazole: Serum concentrations of lamivudine may be elevated, increasing the pharmacologic and adverse effects. Zalcitabine: Lamivudine and zalcitabine may inhibit the intracellular phosphorylation of each other.

Drug Assesment ::

 Assessment/Interventions

• Obtain patient history, including drug history and any known allergies. Note patient’s weight and history of renal impairment (Ccr less than 50 mL/min) or liver impairment.
• Ensure that patient is not receiving abacavir, lamivudine, or zidovudine in other dose forms.
• Do not administer to patient weighing less than 90 lbs.
• Ensure that CBC is obtained prior to starting and periodically during therapy.

Discontinue use and notify health care provider immediately if skin rash or 1 or more symptoms from at least 2 of the following groups are noted: fever; nausea, vomiting, diarrhea, abdominal pain; fatigue, muscle aches, malaise; sore throat; shortness of breath; cough. If hypersensitivity reaction is documented then ensure that reaction is reported to Abacavir Hypersensitivity Register as noted in the package insert.
