Dosing and administration chart

For PsA patients at high risk for joint damage according to clinical judgement, a dose of 100 mg every 4 weeks may be considered1

In PsA clinical studies, an increased incidence of liver enzyme elevations was observed in patients treated with TREMFYA® q4w compared to patients treated with TREMFYA® q8w or placebo. When prescribing TREMFYA® q4w in psoriatic arthritis, it is recommended to evaluate liver enzymes at baseline and thereafter according to routine patient management. If increases in ALT or AST are observed and drug-induced liver injury is suspected, TREMFYA® should be temporarily interrupted until this diagnosis is excluded1
