What happens to the lungs when the patient gets just the propellent because of the medical staff failing to properly instruct the patient on this product? My husband got to much propellent because he didn't have instruction and his lungs seized up. Now he has trouble at least once a day with his breathing and he isn't doing anything.
The propellant in Proventil, HFA-134 (hydrofluroalkane) may act as an irritant to some asthmatics however studies have shown that HFA's are as safe as the older CFC (chloroflurocarbons).
It is common for first time users of inhalers to have problems initially. Side-effects from propellant overdose has not been a problem. As your husbands technique improves he should get more bronchodilator relief from his inhaler.
