Product proprietary name: MILUTIN
Dosage form and strength: Film coated tablet and 50/300/300 mg
A interaction study with the UGT1A1 inhibitor, atazanavir, did not result in a clinically
meaningful increase in the plasma concentrations of dolutegravir. Tenofovir, ritonavir,
lopinavir/ritonavir, darunavir/ritonavir, rilpivirine, boceprevir, telaprevir, prednisone, rifabutin and
omeprazole had no or a minimal effect on dolutegravir pharmacokinetics, therefore no
LUVIGEN dose adjustment is required when co-administered with these medicines.

Non-nucleoside Reverse Dolutegravir ↓
Etravirine decreased dolutegravir plasma
concentration, which may result in loss of
virologic response and possible resistance
to dolutegravir. LUVIGEN should not be

The recommended dose of LUVIGEN is 50
mg twice daily when co-administered with
efavirenz. Alternative combinations that do
not include efavirenz should be used
where possible in INI-resistant patients.
Co-administration with nevirapine has the
potential to decrease dolutegravir plasma
concentration due to enzyme induction and
has not been studied. Effect of nevirapine
on dolutegravir exposure is likely similar to
or less than that of efavirenz. The

Atazanavir increased dolutegravir plasma
concentration. No dose adjustment is
necessary.
