The Duolin Inhaler is used to treat chronic obstructive pulmonary disease (COPD) (a lung disorder in which the flow of air to the lungs is blocked). It aids in the relaxation of the muscles of the airways, making breathing easier. It alleviates coughing, wheezing, and shortness of breath.
Your doctor will advise you on how frequently you should use your inhaler. The effects of this medication may be felt after a few days, but they will peak after a few weeks. This prescription must be taken on a regular basis to be successful, so even if you don’t have any symptoms, keep taking it.
