From letter to CMAJ:

Recently Health Canada has approved a new combination inhaler , “Zenhale”, combining the ICS mometasone furoate and a rapid but long acting bronchodilator formoterol. This controller inhaler comes as a blue inhaler?
From Zenhale leaflet:
ZENHALE is used twice a day to help people 12 years of age or older who need treatment for asthma and the doctor recommends a combination product. ZENHALE is not a rescue medication. Your doctor should prescribe a rescue medication for you. Use the rescue medication if you have sudden asthma symptoms.
ZENHALE is for patients with asthma that:
• was not well controlled with other asthma controlling medications or
• is severe enough that the doctor recommends starting asthma treatment with two asthma medications
