Asthma Home > Is Ventolin Dangerous?

Some Ventolin Warnings and Precautions

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