Asthma Home > Important Safety Concerns With Proair HFA

Some Proair HFA Warnings and Precautions

Following are some warnings and precautions to be aware of with Proair HFA:
  • Tell your healthcare provider immediately if you are using Proair HFA more frequently than usual. Asthma symptoms can worsen very quickly and can become a medical emergency.
  • Using Proair HFA alone is rarely the best asthma treatment. Your healthcare provider should consider prescribing additional asthma medications.
  • Rarely, Proair HFA can make bronchospasms (spasms of the airways) worse, which is exactly the opposite of what should happen. Tell your healthcare provider immediately if Proair HFA makes your asthma worse.
  • Proair HFA can have a stimulatory effect on the heart and blood pressure. As a result, a fast heart rate (tachycardia), high blood pressure (hypertension), or irregular heart rhythms (arrhythmias) may occur -- though low blood pressure (hypotension) is also possible. Make sure your healthcare provider knows (prior to treatment with Proair HFA) if you have heart disease or high blood pressure. He or she may wish to use caution if he or she recommends Proair HFA in your case.
  • People with an overactive thyroid (hyperthyroidism), diabetes, or epilepsy should use caution when taking Proair HFA, since Proair HFA may worsen these conditions or increase the risk of side effects.
  • Do not puncture the Proair HFA canister or keep it near an open flame, as the contents are under pressure.
  • Proair HFA can interact with certain other medications (see Proair HFA Drug Interactions).
  • Proair HFA is considered a pregnancy Category C medication. This means that Proair HFA may not be safe to use during pregnancy. Talk with your healthcare provider about the risks and benefits of using Proair HFA during pregnancy (see Proair HFA and Pregnancy for more information).
  • It is not known whether Proair HFA passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, be sure to talk with your healthcare provider about using Proair HFA (see Proair HFA and Breastfeeding for more information).
