Vilanterol trifenatate is a long-acting beta 2 agonist. It causes bronchodilation by relaxing the muscles in the breathing passages.


Do not use vilanterol in these cases:

  • Known hypersensitivity to vilanterol or any ingredient in the formulation.

  • Known severe hypersensitivity to milk proteins

Do not use for relief of acute symptoms.  Use a short-acting bronchodilator in these cases - they work more quickly.

Use vilanterol with caution:

  • in patients with seizure disorders
  • in patients with heart disorders
  • in patients with overactive thyroid

Drug interactions:

  • ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, clarithromycin, conivaptan, indinavir, itraconazole, lopinavir, nefazodone, nelfinavir, saquinavir, telithromycin, troleandomycin, voriconazole). They may increase the blood levels of vilanterol
  • MAOI medications (e.g., phenelzine)
  • tricyclic antidepressants (e.g., amitriptyline, nortriptyline)
  • Beta-blockers (e.g. propranolol, acebutolol)
  • Diuretics or "water pills" (e.g. furosemide, hydrochlorothiazide)

Use in pregnancy: May interfere with uterine contractility. Carefully weigh benefit versus risk.  Consult with your doctor or pharmacist before use.
