- Carvedilol + Amiodarone— CYP2C9 and P-glycoprotein inhibitor increases S(-)-enantiomer concentrations at least 2-fold, enhancing beta-blocking ac…
- Carvedilol + Aripiprazole Lauroxil— Antihypertensive drug whose effect may be enhanced by aripiprazole's alpha adrenergic antagonism. Avoid concomitant use.
- Carvedilol + Clonidine— May cause hypotension and bradycardia; beta-blocker should be discontinued first when terminating concomitant therapy.
- Carvedilol + Digitalis Glycosides— Digitalis glycosides and carvedilol both slow atrioventricular conduction and decrease heart rate, increasing bradycardi…
- Carvedilol + Digoxin— Both drugs slow atrioventricular conduction and decrease heart rate, increasing risk of bradycardia; digoxin concentrati…
- Carvedilol + Fluconazole— CYP2C9 inhibitor may enhance beta-blocking activity when used with carvedilol, resulting in further slowing of heart rat…
- Carvedilol + Mao Inhibitors— May increase risk of hypotension and severe bradycardia due to catecholamine depletion.
- Carvedilol + Monoamine Oxidase Inhibitors (Maois)— May increase risk of hypotension and/or severe bradycardia through catecholamine depletion combined with beta-blockade.
- Carvedilol + Reserpine— Hypotensive agent that may increase risk of hypotension and/or severe bradycardia when combined with carvedilol.
- Carvedilol + Talazoparib— P-gp inhibitor that increases talazoparib concentrations; avoid coadministration or reduce talazoparib dose and monitor …
Moderate (14)
- Carvedilol + Cimetidine— Hepatic metabolism inhibitor that increases carvedilol AUC by approximately 30% with no change in Cmax.
- Carvedilol + Cinacalcet— CYP2D6 substrate; cinacalcet is a strong CYP2D6 inhibitor. Dose adjustment may be required for concomitant CYP2D6-metabo…
- Carvedilol + Cinacalcet Hydrochloride— Cinacalcet is a strong CYP2D6 inhibitor. Dose adjustments may be required for concomitant CYP2D6 substrate medications.
- Carvedilol + Cyclosporine— Carvedilol may increase cyclosporine trough concentrations; approximately 30% of patients required cyclosporine dose red…
- Carvedilol + Diltiazem— Calcium channel blocker may affect ECG and/or blood pressure when used with carvedilol.
- Carvedilol + Fluoxetine— CYP2D6 inhibitor expected to increase blood levels of carvedilol R(+) enantiomer, potentially increasing vasodilating ef…
- Carvedilol + Insulin Human— Carvedilol may enhance insulin action; monitor for hypoglycemia.
- Carvedilol + Paroxetine— CYP2D6 inhibitor expected to increase blood levels of carvedilol R(+) enantiomer, potentially increasing vasodilating ef…
- Carvedilol + Patiromer— Patiromer binds carvedilol, potentially reducing systemic exposure and clinical efficacy. Separate dosing by at least 3 …
- Carvedilol + Propafenone— CYP2D6 inhibitor expected to increase blood levels of carvedilol R(+) enantiomer, potentially increasing vasodilating ef…
- Carvedilol + Quinidine— CYP2D6 inhibitor expected to increase blood levels of carvedilol R(+) enantiomer, potentially increasing vasodilating ef…
- Carvedilol + Rifampin— May decrease carvedilol levels, potentially reducing therapeutic efficacy.
- Carvedilol + Ubrogepant— BCRP and/or P-gp inhibitor that may increase ubrogepant exposure. Dose adjustment recommended.
- Carvedilol + Verapamil— Calcium channel blocker may affect ECG and/or blood pressure when used with carvedilol.
