Triumeq Dosage

Screening for HLA−B*5701 Allele prior to Initiating TRIUMEQ

Screen for the HLA‑B*5701 allele prior to initiating therapy with TRIUMEQ or TRIUMEQ PD.

Testing prior to or When Initiating Treatment with TRIUMEQ

Prior to or when initiating TRIUMEQ or TRIUMEQ PD, test patients for HBV infection.

Overview of TRIUMEQ Dosage Forms

TRIUMEQ is available in two dosage forms. Do not substitute TRIUMEQ tablets and TRIUMEQ PD tablets for oral suspension on a milligram-per-milligram basis due to differing pharmacokinetic profiles for the dolutegravir component.

•

TRIUMEQ tablets: 600 mg of abacavir, 50 mg of dolutegravir, and 300 mg of lamivudine. TRIUMEQ is recommended in adults and pediatric patients weighing at least 25 kg.

•

TRIUMEQ PD tablets for oral suspension: 60 mg of abacavir, 5 mg of dolutegravir, and 30 mg of lamivudine. TRIUMEQ PD is recommended in pediatric patients weighing 6 kg to less than 25 kg.

•

Because TRIUMEQ PD is a fixed-dose tablet and the dosage of individual components cannot be adjusted, it may lead to a suboptimal dosing for patients weighing ≥25 kg. TRIUMEQ PD is not recommended in patients weighing 25 kg or more.

Recommended Dosage in Adults

TRIUMEQ is a fixed-dose combination product containing 600 mg of abacavir, 50 mg of dolutegravir, and 300 mg of lamivudine. The recommended dosage regimen of TRIUMEQ in adults is one tablet once daily orally with or without food. Do not use TRIUMEQ PD in adults.

Recommended Dosage and Administration Instructions for Pediatric Patients Weighing at Least 6 kg

The dosage and dosage form recommended for pediatric patients varies by weight as shown in Table 1 below.

Administer TRIUMEQ PD tablets for oral suspension with or without food. Instruct patients (or instruct caregivers) to fully disperse the tablets for oral suspension in 20 mL of drinking water (if using 4, 5, or 6 tablets for oral suspension) or 15 mL (if using 3 tablets for oral suspension) in the supplied cup; swirl the suspension so that no lumps remain. After full dispersion, administer the oral suspension within 30 minutes of mixing. Do not swallow the tablets for oral suspension whole, and do not chew, cut, or crush the tablets.

For children unable to use the supplied cup, an appropriate-sized syringe may be used to administer the oral suspension.

Administer TRIUMEQ tablet with or without food. Do not chew, cut, or crush the tablet.

Dosage Recommendation with Certain Concomitant Medications

The dolutegravir dose in TRIUMEQ (50 mg) and TRIUMEQ PD (5 mg) is insufficient when coadministered with medications listed in Table 2 that may decrease dolutegravir concentrations; the following dolutegravir dosage regimen is recommended.

Not Recommended Due to Lack of Dosage Adjustment

Because TRIUMEQ and TRIUMEQ PD are fixed-dose tablets and cannot be dose adjusted, TRIUMEQ and TRIUMEQ PD are not recommended in:

•

patients with creatinine clearance <30 mL/min and pediatric patients with a similar degree of renal impairment based on age-appropriate renal function assessment. There are no data available on the use of lamivudine, a component of TRIUMEQ and TRIUMEQ PD, in pediatric patients with renal impairment.

•

patients with mild hepatic impairment. TRIUMEQ and TRIUMEQ PD are contraindicated in patients with moderate or severe hepatic impairment.
