Crestor (Rosuvastatin Calcium) - Drug Interactions, Contraindications, Overdosage, etc

 
 



DRUG INTERACTIONS

Cyclosporine

Cyclosporine significantly increased rosuvastatin exposure. Therefore, in patients taking cyclosporine, therapy should be limited to CRESTOR 5 mg once daily. [ see Dosage and Administration (2.5), Warnings and Precautions (5.1), and Clinical Pharmacology ].

Gemfibrozil

Gemfibrozil significantly increased rosuvastatin exposure. Therefore, combination therapy with CRESTOR and gemfibrozil should be avoided. If used, do not exceed CRESTOR 10 mg once daily. [ see Dosage and Administration (2.6) and Clinical Pharmacology ].

Lopinavir/Ritonavir

The combination of lopinavir and ritonavir significantly increased rosuvastatin exposure. Therefore, in patients taking a combination of lopinavir and ritonavir, the dose of CRESTOR should be limited to 10 mg once daily. The effect of other protease inhibitors on rosuvastatin pharmacokinetics has not been examined. [ see Dosage and Administration (2.5), Warnings and Precautions (5.1) and Clinical Pharmacology ]

Coumarin Anticoagulants

CRESTOR significantly increased INR in patients receiving coumarin anticoagulants. Therefore, caution should be exercised when coumarin anticoagulants are given in conjunction with CRESTOR. In patients taking coumarin anticoagulants and CRESTOR concomitantly, INR should be determined before starting CRESTOR and frequently enough during early therapy to ensure that no significant alteration of INR occurs. [ see Warnings and Precautions (5.3) and Clinical Pharmacology ]

Niacin

The risk of skeletal muscle effects may be enhanced when CRESTOR is used in combination with niacin; a reduction in CRESTOR dosage should be considered in this setting [ see Warnings and Precautions (5.1)]

Fenofibrate

When CRESTOR was coadministered with fenofibrate no clinically significant increase in the AUC of rosuvastatin or fenofibrate was observed. The benefit of further alterations in lipid levels by the combined use of CRESTOR with fibrates should be carefully weighed against the potential risks of this combination. [ see Warnings and Precautions (5.1) and Clinical Pharmacology ].

OVERDOSAGE

There is no specific treatment in the event of overdose. In the event of overdose, the patient should be treated symptomatically and supportive measures instituted as required. Hemodialysis does not significantly enhance clearance of rosuvastatin.

CONTRAINDICATIONS

CRESTOR is contraindicated in the following conditions:

  • Patients with a known hypersensitivity to any component of this product. Hypersensitivity reactions including rash, pruritus, urticaria and angioedema have been reported with CRESTOR [ see Adverse Reactions (6.1)].

  • Patients with active liver disease, which may include unexplained persistent elevations of hepatic transaminase levels [ see Warnings and Precautions ].

  • Women who are pregnant or may become pregnant. Because HMG-CoA reductase inhibitors decrease cholesterol synthesis and possibly the synthesis of other biologically active substances derived from cholesterol, CRESTOR may cause fetal harm when administered to pregnant women. Additionally, there is no apparent benefit to therapy during pregnancy, and safety in pregnant women has not been established. If the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus and the lack of known clinical benefit with continued use during pregnancy. [ see Use in Specific Populations (8.1) and Nonclinical Toxicology ]

  • Nursing mothers. Because another drug in this class passes into breast milk, and because HMG-CoA reductase inhibitors have the potential to cause serious adverse reactions in nursing infants, women who require CRESTOR treatment should be advised not to nurse their infants. [ see Use in Specific Populations ].
