Safety Information

  • Do not use in combination with other LABA containing medicines for any reason.
  • People with asthma who take long-acting beta2-adrenergic agonist (LABA) medicines such as formoterol (one of the medicines in DULERA), have an increased risk of death from asthma problems. It is not known whether mometasone furoate, the other medicine in DULERA, reduces the risk of death from asthma problems seen with formoterol.
