Common, usually harmless effects
- A brief increase in coughing as the mist reaches your airways and loosens mucus — it often settles within a minute or two.
- A mild taste of the medication or saline.
- Cool mist or slight residue on the face when using a mask — this is normal.
- Mild shakiness or a faster heartbeat with bronchodilators like albuterol, which typically passes quickly.
Effects tied to specific medications
Bronchodilators (such as albuterol) can cause jitteriness, a faster pulse, or restlessness. Inhaled steroids (such as budesonide) can occasionally cause a hoarse voice or oral thrush — rinsing your mouth after a steroid treatment helps prevent this. Discuss any bothersome effect with the prescriber rather than stopping on your own.How to reduce side effects
Sit upright, breathe slowly and steadily, and keep treatments to the prescribed dose and frequency. Clean the device per the cleaning guide so residue and bacteria don’t build up. If a mask irritates the skin, make sure it fits well and wipe the face afterward.When to call a doctor
Contact your doctor if you notice a pounding or irregular heartbeat, chest pain, worsening wheeze or breathlessness during treatment, or symptoms that aren’t improving as expected. Treat severe breathing difficulty as an emergency and call 911.Is the nebulizer itself ever the problem?
Rarely. If mist output is weak, the device sputters, or treatments take much longer than usual, it’s usually a cleaning or hardware issue — see troubleshooting — not a side effect.
