Pharmacy Author:
Medical and Pharmacy Editor:

Amlodipine significantly increases blood levels of simvastatin (Zocor). The dose of simvastatin should be limited to 20 mg daily by patients taking amlodipine.

Ketoconazole (Nizoral, Extina, Xolegel, Kuric), itraconazole (Sporanox), ritonavir (Norvir) and other drugs that are strong inhibitors of amlodipine inactivation in the liver increase blood levels of amlodipine, resulting in excessive blood pressure reduction.

PREGNANCY: Generally, amlodipine is avoided in pregnancy, and by nursing mothers and children although there are no adequate studies of amlodipine use during pregnancy.

NURSING MOTHERS: It is not known whether amlodipine is excreted in breast milk. Generally, amlodipine is avoided in pregnancy, and by nursing mothers and children.
