Intentional overdose of dolutegravir/abacavir/lamivudine (Triumeq) in a 26-year-old man.

Triumeq is a single-tablet regimen for patients with HIV infection comprising dolutegravir, abacavir and lamivudine. Overdoses with Triumeq have not been reported previously. We present a case of a 26-year-old man who presented to our hospital after intentionally ingesting 30 tablets of Triumeq. An intoxication with Triumeq can lead to several side effects. An overdose of abacavir and lamivudine can cause mitochondrial toxicity and lactic acidosis. An intoxication with dolutegravir appears to be relatively harmless. As Triumeq will be used on a regular basis as treatment for patients with HIV-1 infection, these intoxications are expected to be encountered more often.
