Summary
Both products contain a long-acting beta2-agonist, so combining them duplicates therapy and increases beta-adrenergic effects such as tachycardia, tremor, hypokalemia and QT prolongation. The risk of arrhythmia is greater than with a single agent.
What this interaction means in plain words
Arformoterol and Fluticasone-vilanterol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Arformoterol belongs to Respiratory; Fluticasone-vilanterol belongs to Respiratory.
Why it happens
Duplicate beta2-adrenergic agonism producing additive cardiovascular and hypokalemic effects.
What to do
Avoid concurrent use of two long-acting beta2-agonists; keep only one LABA and stop the other. Monitor heart rate, ECG and serum potassium if overlap occurs.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
