Warnings and precautions

Liver icon

Elevation of aminotransferases1

Treatment with SKYCLARYS can cause an elevation in hepatic transaminases (ALT and AST).

Monitor ALT, AST, and total bilirubin prior to initiation of SKYCLARYS, every month for the first 3 months of treatment, and periodically thereafter.

If transaminases increase to levels greater than 5 times the ULN, or greater than 3 times the ULN with evidence of liver dysfunction (eg, elevated bilirubin), immediately discontinue SKYCLARYS and repeat liver function tests as soon as possible.

If transaminase levels stabilize or resolve, SKYCLARYS may be reinitiated with an appropriate increased frequency of monitoring of liver function.

Maximum increases in ALT and AST occurred within 12 weeks after starting SKYCLARYS. Increases in serum aminotransferases were generally asymptomatic and reversible following discontinuation of SKYCLARYS.

Heart icon

Elevation of B-type natriuretic peptide (BNP)1

Treatment with SKYCLARYS can cause an increase in BNP, a marker of cardiac function. Elevations in BNP may indicate cardiac failure and should prompt an evaluation of cardiac function. Check BNP prior to initiation of SKYCLARYS.

Monitor patients for the signs and symptoms of fluid overload, such as sudden weight gain (3 pounds or more of weight gain in one day, or 5 pounds or more of weight gain in a week), peripheral edema, palpitations, and shortness of breath. Management of fluid overload and heart failure may require discontinuation of SKYCLARYS.

Lipid abnormalities1

Treatment with SKYCLARYS can cause changes in cholesterol.

Mean increases were observed within 2 weeks of initiation of SKYCLARYS and returned to baseline within 4 weeks of discontinuing treatment. Assess lipid parameters prior to initiation of SKYCLARYS and monitor periodically during treatment.
