  • Shake the inhaler bottle to mix the medication and aerosol propellant.

  • Remove the mouthpiece and cap. Note: Some metered dose inhalers have a spacer built into the inhaler. Pull the spacer away from the section holding the medication canister until it clicks into place.

  • Insert the metal stem on the bottle into the small hole on the flattened portion of the mouthpiece. Then turn the bottle upside down.

  • Have the patient exhale; then place the mouthpiece in his mouth and close his lips around it.

  • As you firmly push the bottle down against the mouthpiece, ask the patient to inhale slowly and to continue inhaling until his lungs feel full. This action draws the medication into his lungs. Compress the bottle against the mouthpiece only once.

  • Remove the mouthpiece from the patient's mouth, and tell him to hold his breath for several seconds to allow the medication to reach the alveoli. Then instruct him to exhale slowly through pursed lips to keep the distal bronchioles open, allowing increased absorption and diffusion of the drug and better gas exchange.

  • Have the patient gargle with normal saline solution, if desired, to remove medication from the mouth and back of the throat. (The lungs retain only about 10% of the inhalant; most of the remainder is exhaled, but substantial amounts may remain in the oropharynx.)

  • Rinse the mouthpiece thoroughly with warm water to prevent accumulation of residue.

Using a turbo-inhaler

  • Hold the mouthpiece in one hand, and with the other hand, slide the sleeve away from the mouthpiece as far as possible.

  • Unscrew the tip of the mouthpiece by turning it counterclockwise.

  • Firmly press the colored portion of the medication capsule into the propeller stem of the mouthpiece.

  • Screw the inhaler together again securely.

  • Holding the inhaler with the mouthpiece at the bottom, slide the sleeve all the way down and then up again to puncture the capsule and release the medication. Do this only once.

  • Have the patient exhale and tilt his head back. Tell him to place the mouthpiece in his mouth, close his lips around it, and inhale once—quickly and deeply—through the mouthpiece.

  • Tell the patient to hold his breath for several seconds to allow the medication to reach the alveoli. (Instruct him not to exhale through the mouthpiece.)

  • Remove the inhaler from the patient's mouth, and tell him to exhale as much air as possible.

  • Repeat the procedure until all the medication in the device is inhaled.

  • Have the patient gargle with normal saline solution, if desired, to remove medication from the mouth and back of the throat. Be sure to provide an emesis basin if the patient needs one.

  • Discard the empty medication capsule, put the inhaler in its can, and secure the lid. Rinse the inhaler with warm water at least once a week.

Using a nasal inhaler

  • Have the patient blow his nose to clear his nostrils.

  • Shake the medication cartridge and then insert it in the adapter. (Before inserting a refill cartridge, remove the protective cap from the stem.)

  • Remove the protective cap from the adapter tip.

  • Hold the inhaler with your index finger on top of the cartridge and your thumb under the nasal adapter. The adapter tip should be pointing toward the patient.

  • Have the patient tilt his head back. Then tell him to place the adapter tip into one nostril while occluding the other nostril with his finger.

  • Instruct the patient to inhale gently as he presses the adapter and the cartridge together firmly to release a measured dose of medication. Be sure to follow the manufacturer's instructions. With some medications, such as dexamethasone sodium phosphate (Turbinaire), inhaling during administration isn't desirable.

  • Tell the patient to remove the inhaler from his nostril and to exhale through his mouth.

  • Shake the inhaler, and have the patient repeat the procedure in the other nostril.

  • Have the patient gargle with normal saline solution to remove medication from his mouth and throat.

  • Remove the medication cartridge from the nasal inhaler, and wash the nasal adapter in lukewarm water. Let the adapter dry thoroughly before reinserting the cartridge.
