Only chanced steroid inhalers from clenil to symbicort (budesonide and formoterol) and x4 in the mornings and evenings when should i see signs of improvement as still having problems sleeping at night what could i do till then?

Steroid inhalers: Steroid or steroid/long-acting bronchodilator combination inhalers for asthma do not take effect quickly,and are not used for immediate relief in asthma exacerbations. If an inhaled bronchodilator such as salbutamol (albuterol) used as-needed is not working well enough and Symbicort (budesonide and formoterol) or similar has not taken effect, oral steroids are sometimes given.This needs to be assessed by the prescribing doc.
