Antihistamine OK: But bronchodilator may need to be discontinued depending on the purpose of the test. If it is used to assess how you are responding to the maintenance treatment, then avoid the rescue inhaler such as albuterol for at least 6 hrs. For diagnostic purpose, inhaled steroid ; singulair (montelukast) need be discontinued for 2 weeks and long-acting bronchodilator 24 hrs. Do talk to your doctor if you have question.
