TRELEGY is a prescription medicine used long term to prevent and control symptoms of asthma for better breathing and to prevent symptoms such as wheezing.
TRELEGY is not used to relieve sudden breathing problems and will not replace a rescue inhaler.
TRELEGY should not be used in children younger than 18 years of age. It is not known if TRELEGY is safe and effective in children younger than 18 years of age.
Important Safety Information
TRELEGY contains vilanterol. Long-acting beta2-adrenergic agonist (LABA) medicines such as vilanterol, when used alone, increase the risk of hospitalizations and death from asthma problems. TRELEGY contains an inhaled corticosteroid (ICS), an anticholinergic, and a LABA. When an ICS and LABA are used together, there is not a significant increased risk in hospitalizations and death from asthma problems.
Do not use TRELEGY to relieve sudden breathing problems. Always have a rescue inhaler with you to treat sudden symptoms.
TRELEGY should not be used in children younger than 18 years of age. It is not known if TRELEGY is safe and effective in children.

Do not use TRELEGY more often than prescribed.
Do not take TRELEGY with other medicines that contain a LABA or an anticholinergic for any reason.Tell your healthcare provider about all your medical conditions and about all the medicines you take.
Call your healthcare provider or get medical care right away if your breathing problems get worse, if you need your rescue inhaler more often than usual or it does not work as well to relieve your symptoms.
