Warning
Oral route (Tablet; Tablet for Suspension)
Hypersensitivity ReactionsSerious and sometimes fatal hypersensitivity reactions, with multiple organ involvement, have occurred with abacavir, a component of the abacavir, dolutegravir, and lamivudine combination. Patients who carry the HLA-B*5701 allele are at a higher risk of a hypersensitivity reaction to abacavir, although, hypersensitivity reactions have occurred in patients who do not carry the HLA-B*5701 allele.The abacavir, dolutegravir, and lamivudine combination is contraindicated in patients with a prior hypersensitivity reaction to abacavir and in HLA-B*5701-positive patients. All patients should be screened for the HLA-B*5701 allele prior to initiating therapy with abacavir, dolutegravir, and lamivudine or reinitiation of therapy with abacavir, dolutegravir, and lamivudine, unless patients have a previously documented HLA-B*5701 allele assessment. Discontinue abacavir, dolutegravir, and lamivudine combination immediately if a hypersensitivity reaction is suspected, regardless of HLA-B*5701 status and even when other diagnoses are possible.Following a hypersensitivity reaction to abacavir, dolutegravir, and lamivudine combination, never restart abacavir, dolutegravir, and lamivudine or any other abacavir-containing product because more severe symptoms, including death, can occur within hours. Similar severe reactions have also occurred rarely following the reintroduction of abacavir-containing products in patients who have no history of abacavir hypersensitivity.Exacerbations of Hepatitis BAll patients with HIV-1 should be tested for the presence of hepatitis B virus (HBV) prior to or when initiating abacavir, dolutegravir, and lamivudine combination. Emergence of lamivudine-resistant HBV variants associated with lamivudine-containing antiretroviral regimens has been reported. If abacavir, dolutegravir, and lamivudine combination is used in patients co-infected with HIV-1 and HBV, additional treatment should be considered for appropriate chronic HBV; otherwise, consider an alternative regime.Severe acute exacerbations of hepatitis B have been reported in patients who are co-infected with HBV and HIV-1 and have discontinued lamivudine, a component of abacavir, dolutegravir, and lamivudine combination. Closely monitor hepatic function in these patients and, if appropriate, initiate anti-HBV treatment.

For Healthcare Professionals
Applies to abacavir / dolutegravir / lamivudine: oral tablet, oral tablet dispersible.
General
The most common side effects were insomnia, headache, fatigue, nausea, and dizziness.
Many of the side effects listed occurred commonly in patients with abacavir hypersensitivity (e.g., nausea, vomiting, diarrhea, fever, lethargy, rash).[Ref]
Hypersensitivity
Hypersensitivity reactions were reported with abacavir and dolutegravir and shared some common features (e.g., fever and/or rash with other symptoms that indicated multi-organ involvement). In general, time to onset was 10 to 14 days for both abacavir- and dolutegravir-associated reactions.
Serious and sometimes fatal hypersensitivity reactions have been reported with abacavir. Such reactions have included multi-organ failure and anaphylaxis and usually occurred within the first 6 weeks of abacavir therapy; however, abacavir hypersensitivity reactions have occurred any time during therapy.
Patients with the human leukocyte antigen subtype B*5701 (HLA-B*5701) allele are at higher risk of abacavir hypersensitivity reactions; however, such reactions have occurred in patients without the HLA-B*5701 allele. Abacavir hypersensitivity was reported in about 8% of patients in 9 clinical trials with abacavir-containing products where patients were not screened for the HLA-B*5701 allele; incidence of suspected abacavir hypersensitivity reactions was 1% in clinical trials where HLA-B*5701 carriers were excluded.
Abacavir hypersensitivity reactions have been characterized by at least 2 of the following key signs/symptoms: (1) fever; (2) rash; (3) gastrointestinal symptoms (including nausea, vomiting, diarrhea, abdominal pain); (4) constitutional symptoms (including generalized malaise, fatigue, achiness); (5) respiratory symptoms (including dyspnea, cough, pharyngitis). Almost all reactions have included fever and/or rash (usually maculopapular or urticarial); however, reactions also reported without fever or rash. Signs/symptoms reported in at least 10% of patients with hypersensitivity reaction have included rash, nausea, vomiting, diarrhea, abdominal pain, dyspnea, cough, fever, fatigue/lethargy, malaise, headache, elevated liver function tests, and myalgia. Other signs/symptoms of hypersensitivity have included mouth ulceration, sore throat, adult respiratory distress syndrome, respiratory failure, edema, lymphadenopathy, hypotension, conjunctivitis, anaphylaxis, paresthesia, lymphopenia, hepatitis, liver failure, myolysis, arthralgia, elevated creatine phosphokinase, elevated creatinine, renal failure, abnormal chest x-ray findings (mainly infiltrates, which were localized), and death.
Symptoms of abacavir hypersensitivity reaction worsened with continued therapy and generally resolved when abacavir was discontinued. Restarting abacavir after a hypersensitivity reaction has resulted in more severe symptoms within hours and included life-threatening hypotension and death. Rarely, life-threatening reactions have occurred within hours after restarting abacavir in patients who stopped it for reasons other than symptoms of hypersensitivity (or who stopped it with only 1 key symptom of hypersensitivity).[Ref]

Renal
Dolutegravir was shown to increase serum creatinine due to inhibition of tubular secretion of creatinine without affecting renal glomerular function. Increased serum creatinine was reported within the first 4 weeks of therapy and remained stable through 144 weeks. In 1 trial, a mean change from baseline of 0.14 mg/dL (range: -0.25 to 0.81 mg/dL) was reported after 144 weeks of therapy in therapy-naive patients. Creatinine increases were similar in therapy-experienced patients.[Ref]

Cardiovascular
Several prospective, observational, epidemiological studies reported an association with the use of abacavir and the risk of MI. Meta-analysis of randomized, controlled clinical trials showed no excess risk of MI in abacavir-treated patients as compared with control subjects. Overall, available data from observational studies and controlled clinical trials showed inconsistency; evidence for causal relationship between abacavir and risk of MI was inconclusive.[Ref]
