What’s New?
The original formulation of the epinephrine inhaler was propelled by chlorofluorocarbons (CFCs). The original formulation was phased out in 2011 because the inhaler used CFCs to move the medicine out of the inhaler so patients could breathe the medicine into their lungs. The United States signed an international agreement, called the Montreal Protocol on Substances that Deplete the Ozone Layer, along with many other countries. In order to comply with the obligations made under the Protocol, participating countries agreed to phase out substances that deplete the ozone layer, including CFCs.
HERE’S WHAT’S NEW
The new inhaler is a CFC-free metered dose inhaler (MDI) that uses epinephrine as its active ingredient, the same active ingredient used in the previous inhaler. The new Primatene® MIST propelled by hydrofluoroalkane (HFA 134a) works differently from the old inhaler containing CFCs. Be sure to read the Consumer Information Insert for detailed directions on how to correctly use your new metered dose inhaler.
CHANGES TO THE ASTHMA MEDICINE CONTAINER:
The new medication container is a pressurized metal canister similar to canisters used in other metered dose inhalers available, instead of the glass container used in the previous inhaler propelled by chlorofluorocarbons (CFCs).
ADDITION OF A SPRAY INDICATOR:
The new Primatene® MIST has a built-in spray indicator that shows how many sprays of asthma medicine you have left in the container. A full container has 160 sprays. After every 20 sprays, the spray indicator number changes.
