1 interaction related to assay interference
Hawthorn (Crataegus) has digoxin-like positive inotropic activity, may modulate P-glycoprotein efflux, and can interfere with serum digoxin immunoassays. Concurrent use raises the risk of additive cardiac effects and erroneous digoxin level readings even though formal pharmacokinetic studies show little change in digoxin AUC.
