Take the missed dose as soon as you remember. Skip the missed dose if it is the time for the next dose of the medication. Do not use additional medicine to compensate the missed dose.



overdoseThe objective and subjective symptoms of Advair Diskus overdose are tremors, headache, and tachycardia.

  • Inhalation of the doses higher than recommended may cause temporary suppression of the hypothalamic-pituitary-adrenal system. Usually, this condition does not require some emergency measures, as in most cases the normal adrenal function is recovered in a few days;
  • Prolonged inhalation of excessive doses may significantly suppress adrenal. There are rare reports of acute adrenal crisis, which occurs mostly in children receiving excessive doses of the drug (several months or years) for a long time. The acute adrenal crisis is manifested through hypoglycemia accompanied by confusion and/or convulsions. Situations which can be a triggering factor for acute adrenal crisis include trauma, surgery, infection.


Antidotes of an overdose are cardioselective β-blockers. In cases when it is necessary to neutralize the action of the drug due to an overdose, the patient should be prescribed the appropriate replacement corticosteroids.

Patients should be aware that it’s forbidden to take doses higher than recommended. Regular evaluation of the therapy effectiveness is important. Reduce Advair dose to the minimum effective one, if possible, to control your asthma symptoms.

In chronic overdose, it is recommended to control the adrenocortical function.
