Stimulants Excess

High caffeine or stimulants may counteract heart-calming effects

Stimulants increase heart rate and blood pressure · minor significance

Medication interactions

Discuss these with a pharmacist before combining

heart-medications Moderate

May enhance effects of cardiac glycosides and heart medications

What to do: Monitor heart function and medication levels

blood-pressure-medications Moderate

May enhance hypotensive effects of blood pressure drugs

What to do: Monitor blood pressure closely and adjust medications

blood-thinners Minor

May increase bleeding risk with anticoagulant medications

What to do: Monitor bleeding parameters and clotting times
