7 DRUG INTERACTIONS Combination of sofosbuvir/velpatasvir/voxilaprevir or ledipasvir/sofosbuvir: Combination increases rosuvastatin tablets exposure. Use with rosuvastatin tablets is not recommended. ( 2.4 , 5.1 , 7.3 , 12.3 ) Cyclosporine and darolutamide : Combination increases rosuvastatin tablets exposure. Limit rosuvastatin tablets dose to 5 mg once daily. ( 2. 4, 5.1 , 7.1 , 7.4 , 12.3 ) Gemfibrozil : Combination should be avoided. If used together, limit rosuvastatin tablets dose to 10 mg once daily. (2.4, 5.1 , 7.2 ) Atazanavir/ritonavir, lopinavir/ritonavir, simeprevir or combination of dasabuvir/ombitasvir/paritaprevir/ritonavir, elbasvir/grazoprevir, sofosbuvir/velpatasvir and glecaprevir/pibrentasvir: Combination increases rosuvastatin tablets exposure. Limit rosuvastatin tablets dose to 10 mg once daily. ( 2.4 , 5.1 , 7.3 , 12.3 ) Regorafenib: Combination increases rosuvastatin exposure. Limit rosuvastatin tablets dose to 10 mg once daily.( 2.4 , 5.1 , 7.5 ) Coumarin anticoagulants : Combination prolongs INR. Achieve stable INR prior to starting rosuvastatin tablets. Monitor INR frequently until stable upon initiation or alteration of rosuvastatin tablets therapy. ( 5.4 , 7.6 ) Concomitant lipid-lowering therapies : Use with fibrates or lipid-modifying doses (≥1 g/day) of niacin increases the risk of adverse skeletal muscle effects. Caution should be used when prescribing with rosuvastatin tablets. ( 5.1 , 7.7 , 7.8 ) 7.1 Cyclosporine Cyclosporine increased rosuvastatin exposure and may result in increased risk of myopathy. Therefore, in patients taking cyclosporine, the dose of rosuvastatin tablets should not exceed 5 mg once daily [ see Dosage and Administration (2.4) , Warnings and Precautions (5.1) , and Clinical Pharmacology (12.3) ]. 7.2 Gemfibrozil Gemfibrozil significantly increased rosuvastatin exposure. Due to an observed increased risk of myopathy/rhabdomyolysis,combination therapy with rosuvastatin tablets and gemfibrozil should be avoided. If used together, the dose of rosuvastatin tablets should not exceed 10 mg once daily [ see Clinical Pharmacology (12.3) ]. 7.3 Anti-viral Medications Coadministration of rosuvastatin with certain anti-viral drugs has differing effects on rosuvastatin exposure and may increase risk of myopathy. The combination of sofosbuvir/velpatasvir/voxilaprevir which are anti-Hepatitis C virus (anti-HCV) drugs, increases rosuvastatin exposure. Similarly, the combination of ledipasvir/sofosbuvir may significantly increase rosuvastatin exposure. For these combinations of anti-HCV drugs, concomitant use with rosuvastatin tablets is not recommended. Simeprevir and combinations of dasabuvir/ombitasvir/paritaprevir/ritonavir, elbasvir/grazoprevir, sofosbuvir/velpatasvir and glecaprevir/pibrentasvir which are anti-HCV drugs, increase rosuvastatin exposure. Combinations of atazanavir/ritonavir and lopinavir/ritonavir, which are anti-HIV-1 drugs, increase rosuvastatin exposure [see Table 4 – Clinical Pharmacology ( 12.3 )] . For these anti-viral drugs, the dose of rosuvastatin tablets should not exceed 10 mg once daily. The combinations of fosamprenavir/ritonavir or tipranavir/ritonavir, which are anti-HIV-1 drugs, produce little or no change in rosuvastatin exposure. No dose adjustment is needed for concomitant use with these combinations [see Dosage and Administration ( 2.4 ) , Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.3 )] . 7.4 Darolutamide Darolutamide increased rosuvastatin exposure more than 5 fold. Therefore, in patients taking darolutamide, the dose of rosuvastatin tablets should not exceed 5 mg once daily [see Dosage and Administration ( 2.4 ) , Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.3 )] . 7.5 Regorafenib Regorafenib increased rosuvastatin exposure and may increase the risk of myopathy.

If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration of either drug. Niacin Clinical Impact: Cases of myopathy and rhabdomyolysis have occurred with concomitant use of lipid-modifying doses (≥1 g/day) of niacin with rosuvastatin tablets. Intervention: Consider if the benefit of using lipid-modifying doses (≥1 g/day) of niacin concomitantly with rosuvastatin tablets outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration of either drug. Colchicine Clinical Impact: Cases of myopathy and rhabdomyolysis have been reported with concomitant use of colchicine with rosuvastatin tablets. Intervention: Consider if the benefit of using colchicine concomitantly with rosuvastatin tablets outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration of either drug. Ticagrelor Clinical Impact: Concomitant use of rosuvastatin tablets and ticagrelor has been shown to increase rosuvastatin concentrations, which may result in increased risk of myopathy. Cases of myopathy and rhabdomyolysis have been reported in patients using both products concomitantly. Cases have occurred more frequently in patients taking 40 mg of rosuvastatin. Intervention: In patients taking concomitant ticagrelor, especially those with additional risk factors for myopathy and rhabdomyolysis, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration of rosuvastatin tablets. 7.2 Drug Interactions that Decrease the Efficacy of Rosuvastatin Tablets Table 6 presents drug interactions that may decrease the efficacy of rosuvastatin tablets and instructions for preventing or managing them. Table 6: Drug Interactions that Decrease the Efficacy of Rosuvastatin Tablets Antacids Clinical Impact: Concomitant aluminum and magnesium hydroxide combination antacid administration decreased the mean exposure of rosuvastatin 50% [see Clinical Pharmacology ( 12.3 )]. Intervention: In patients taking antacid, administer rosuvastatin tablets at least 2 hours before the antacid. 7.3 Rosuvastatin Tablets Effects on Other Drugs Table 7 presents rosuvastatin tablets effect on other drugs and instructions for preventing or managing them. Table 7: Rosuvastatin Tablets Effects on Other Drugs Warfarin Clinical Impact: Rosuvastatin significantly increased the INR in patients receiving warfarin [see Clinical Pharmacology ( 12.3 )]. Intervention: In patients taking warfarin, obtain an INR before starting rosuvastatin tablets and frequently enough after initiation, dose titration or discontinuation to ensure that no significant alteration in INR occurs. Once the INR is stable, monitor INR at regularly recommended intervals.
