Smiley face Smiley face

Monitor/Modify Tx

Smiley face Smiley face cranberry extract (cranberry (Vaccinium spp.)) + warfarin (generic)

Caution Advised

Smiley face Smiley face cranberry extract (cranberry (Vaccinium spp.)) + Dexedrine (dextroamphetamine)

Caution Advised

Additional Considerations

Smiley face Smiley face dextroamphetamine in Dexedrine

add MAO inhibitor to Interaction Check if recent (14 days) use

avoid combo with beverages or products containing ethanol and Mydayis; combo may incr. dextroamphetamine release rate, levels, risk of adverse effects, decr. duration of efficacy

Smiley face Smiley face infliximab

caution advised with narrow therapeutic index drugs; chronic inflammatory conditions may alter metabolic enzyme formation; tx with immune modulators may reverse this effect, resulting in altered levels of concomitant drugs

Smiley face Smiley face warfarin

monitor INR more frequently when starting, adjusting, or stopping other drugs, including short-term therapies, OTC drugs, herbal supplements; drug interaction mechanisms do not always predict anticoagulation effects due to high inter- and intra-patient variability
