Asthma Management: Possible Side Effects of Your Medications


  • Asthma medications, like most medications, can cause side effects.
  • When given a prescription for a new medicine, ask what side effects might be expected, which are uncommon, and which should be reported to your healthcare provider. Side effects can depend on the type of medication and device used to take it.
  • Side effects commonly associated with asthma medications are: an increased heart rate, dizziness, shakiness, feeling jittery or nervous, coughing, a sore throat, dry mouth or hoarseness, a bad taste in the mouth or thrush, which is a yeast infection in the mouth. Thrush and hoarseness can be prevented by rinsing your mouth and spitting out the water or brushing your teeth after using inhaled steroid medications.
  • Let your healthcare provider know about these or any other side effects you experience. Also mention if you notice a worsening of any asthma symptoms such as coughing, wheezing, or if your symptoms cause you to wake up at night.
  • And tell them if you suspect you have thrush. It can be treated with an oral anti-fungal medication. There may be a different medication you can take, or your dosage may be changed to help reduce the side effects.
  • Expected side effects are usually temporary. So if you experience them, don’t stop taking your medication. An unexpected side effect might be that your asthma symptoms worsen after taking your medication.
  • Being aware of possible medication side effects is an important part of managing your asthma. But if you experience any, don’t give up. Together you and your provider will find the right medications that work for you.
