To use the inhaler:

• Shake the inhaler several times and uncap the mouthpiece. Breathe out fully and place your lips around the mouthpiece. Take a deep, slow breath as you push down on the canister. Hold your breath for several seconds, then exhale slowly.
• If you take more than one dose at a time, wait for at least 1 full minute, then repeat the procedure.
• Keep your inhaler clean and dry. Keep the mouthpiece capped to avoid getting dirt inside it. Clean your inhaler once a day by removing the canister and immersing the mouthpiece in warm water. Allow the parts to dry, then reassemble the inhaler.

To use the solution for nebulization:

• Measure the correct amount of medication with the dropper provided or select the prescribed number of ampules. Transfer the liquid into the medication chamber of the nebulizer. If your medication has a dropper, do not allow the dropper to touch any surface including your hands or the chamber of the nebulizer. Dilute the medication with normal saline if prescribed by your doctor.
• Attach the mouthpiece or face mask to the drug chamber. Then, attach the drug chamber to the compressor. Sit upright, in a comfortable position, and put the mouthpiece into your mouth or put the face mask on, covering the nose and mouth. Breathe slowly and evenly until all of the medicine has been inhaled (usually 5 to 15 minutes). The treatment is complete when no more mist is formed by the nebulizer and the drug chamber is empty.
• Clean the nebulizer after a treatment as directed by the manufacturer.

If you also use a steroid inhaler, use your isoetharine inhaler or nebulization solution first to open up your airways, then use the steroid inhaler as directed.
