Summary
Telavancin can prolong the QT interval, and epinephrine has sympathomimetic effects that may provoke arrhythmias. Systemic use together may add to the risk of ventricular arrhythmia, especially with hypokalemia. Inhaled racemic epinephrine has low systemic exposure, so the real-world risk is generally small.
What this interaction means in plain words
Epinephrine racemic and Telavancin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Additive proarrhythmic effects: telavancin prolongs ventricular repolarization while adrenergic stimulation increases arrhythmia susceptibility.
What to do
Obtain an ECG if systemic or high-dose epinephrine is needed and correct potassium and magnesium abnormalities. No action is usually needed for inhaled racemic epinephrine in patients without other QT risk factors.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
