Medically reviewed by Drugs.com. Last updated on Sep 21, 2021.

Applies to the following strengths: 75 mg/mL; 150 mg/mL

Usual Adult Dose for Hyperlipidemia

75 mg subcutaneously every 2 weeks OR 300 mg subcutaneously once every 4 weeks
-For inadequate LDL-C (low density lipoprotein) response, may adjust dose to 150 mg subcutaneously every 2 weeks
Maximum dose: 150 mg subcutaneously every 2 weeks

Patients with Heterozygous Familial Hypercholesterolemia (HeFH) undergoing LDL Apheresis: 150 mg subcutaneously once every 2 weeks; dose may be administered without regard to the timing of apheresis

Comments:
-Assess LDL-C when clinically appropriate, the LDL-C lowering effect may be measured as early as 4 weeks after initiating therapy.
-In some patients, LDL-C can vary considerably during 4-week dosing intervals, therefore measure LDL-C just prior to the next scheduled dose.
-If LDL-C reduction is inadequate, consider adjusting dose to 150 mg every 2 weeks starting new dose on the next scheduled dosing date.

Uses:
-As an adjunct to diet, alone or in combination with other lipid-lowering therapies for the treatment of primary hyperlipidemia including HeFH to reduce LDL-C.
-To reduce the risk of myocardial infarction, stroke, and unstable angina requiring hospitalization in adults with established cardiovascular disease.
