Tear open the sealed foil wrapper along the jagged edge. To open your Seretide Accuhaler, hold the case in one hand and put the thumb of your other hand on the thumb grip. Push your thumb away from you until you hear a click. This opens the mouthpiece.
Hold the Accuhaler flat with the mouthpiece towards you. Slide the lever away from you until you hear a click. This places a dose of the medicine in the mouthpiece.
Hold the Accuhaler away from your mouth, breathe out as far as is comfortable. Seal your lips around the mouthpiece and breathe in steadily and deeply through your mouth as far as is comfortable. Remove the inhaler and hold your breath for up to 10 seconds (or as long as you comfortably can) and then breathe out slowly.
Close the Seretide Accuhaler by sliding the thumb grip towards you, ready for the next use. Rinse your mouth with water.
