What are the side effects of using my CPAP machine?

You might experience some discomfort while adjusting to your CPAP therapy.

The main adverse effects that people mention from CPAP therapy are skin irritation from the mask, as well as dry eyes, nasal congestion and airway dryness from the air. Most people will tell you that the most difficult part of CPAP therapy is getting used to using it initially. You’ll need time and patience to adapt to CPAP, but you should start to notice the benefits within 2 weeks of using it all night.1
