Do metered-dose inhalers contain chlorofluorocarbons and, do they deplete the ozone?
Barry Make, MD — Metered-dose inhalers are “puffers” which hold a medication that can be inhaled into the lungs. Traditionally, these delivery devices do contain fluorocarbons that can harm the environment. Newer medications for the lungs are now becoming more widely available either in metered-dose inhalers which do not have fluorocarbons or which have medication in a powder form which also do not have fluorocarbons. Your doctor should know which agents are available and what new ones are coming on the market. LUNG LINE also knows about the available medication delivery systems; 1-800-222-LUNG (5864) at National Jewish Health.Barry Make, MD– Another common question is how to take an inhaled medication with a metered-dose inhaler. The proper technique is not easy! Remember to shake the canister first.
