Arnuity Ellipta comes with a drug information leaflet with illustrations describing its use. Your doctor will also provide specific instructions. If you are unsure how to use the inhaler, speak to a doctor or pharmacist as proper use is necessary to receive the best results. You will have to inhale this deeply for the medication to reach the lungs. You may not taste anything or feel any sensation that is working. Do not exhale into the mouthpiece. If you need to take another inhaler to manage symptoms. Wait a minute before using a different inhaler. To prevent irritation or infection in your mouth or throat (thrush) from leftover medication, you should rinse your mouth out with water. Do not swallow any rinse water. You should not stop using Arnuity Ellipta unless instructed by your doctor. Symptoms can return even if you stop treatment prematurely If you miss your inhalation once daily dose, simply skip the missed dose and take the next one as expected. Do not take an extra dose to make up for the missed one as this will not improve your condition and may increase your risk of side effects. This can contribute to other eye problems including increased pressure in your eyes and glaucoma. You should have regular eye exams when taking this medication.
